AIR-ANT2506

Hi,
I have installed an access-point 1242 and for arise signal I have installed also antenna AIR-ANT2506 instead of AIR-ANT4941.
Have to I modify some parameter on configuration ?
best regards
Lorezo

Hi Lorenzo,
You probably want to set the Left or Right Primary (I'm not on site right now so I can't see or remember) and take the setting out of Diversity;
Use the antenna configuration interface command to configure the radio receive or transmit antenna settings. Use the no form of this command to reset the receive antenna to defaults.
[no] antenna {receive | transmit} {diversity | left | right}
Syntax Description
receive
Specifies the antenna that the access uses to receive radio signals
transmit
Specifies the antenna that the access uses to transmit radio signals
diversity
Specifies the antenna with the best signal
left
Specifies the left antenna
right
Specifies the right antenna
Defaults
The default antenna configuration is diversity
Examples
This example shows how to specify the right receive antenna option:
AP(config-if)# antenna receive right
This example shows how to set the receive antenna option to defaults:
AP(config-if)# no antenna receive

AIR-ANT2506 problem

i have AIR-ANT2506 installed on ap's for outside and it seems as though i am loosing signal strentgh on them when i investigate the ant is filling up with water due to the lip that is on them. is there a model better suited for my needs.

that is probably why they collected water, antennas are designed to be installed with the cable exiting the bottom. there is no drain hole when they are mounted inverted.
when used indoors you would mount them inverted but outdoors right side up.

Cisco AIR-ANT2506 Compatibility

Hi,
I need an omni antenna with the specifications of AIR-ANT2506 for a Lighweight AP 1242 for outdoor installation. The AP is compatible with the antenna, but the description of the antenna says that it is a 2.4 GHz Bridge Antenna. Does this mean that it is not suitable or even unusable for ordinary Lighweight implementation, but only for Bridge installations. I should cover an area around the entrance of a store...
Thanks in advance for any suggestions!

I am trying to get internet into a number of properties on an estate. I am not sure of the best solution as we are also quite remote / rural, hence why we have a satellite internet set up and not using internet through a telephone exchange as we are too far away from it.
I am looking for the cheapest solution, and am happy to have the properties hard wired laying ethernet cable to each property, but if I can achieve internet in each property with wireless then that is probably a better solution.
I have attached a birds eye view diagram of the properties, showing where the current satellite modem is located, and where the antenna is mounted (It is about 1 metre above the roof line, but on each property the roofing is corrugated iron)
I have line of site with the antenna to at least 3 of the properties (Crag house, Sams, The Bothy and probably The Barn & maybe just about Oak)
I therefore need internet access internally in these properties. I do, as a separate project and if possible, a property 1.2miles across a loch that we have line of site with that if possible we would like internet to be broadcast across there, but the first port is to get the properties on the estate hooked up with wireless.
If you have any suggestions of what Access Points would work, they do not have to be whizzbang because we only have broadband speed currently of 512k, upscalable to 3MB.
I also do not understand how being able to run 50-100ft coax cable from the antenna to the AP works, when I was told that for every 10ft of cable, you lose about 2dBi from the antenna, is this true??
I have just attached a photo of 2 antennas on the corner of the white building (1 is the AIR-ANT2506, the other taller one is an itellite 12dBi antenna which I haven't yet tried)
You can see the white building to the left that needs to be wireless, the building in the middle of the picture, and the 2 just to the right of this building. There is a further one behind the grass you see in the middle of the picture, and a final property that isn't in the picture, but if you look at the excel spreadsheet you should be able to work out the buildings)

Antenna mounting question - AIR-ANT2506

I was told by a wifi tech that the "pipe bomb" antenna [air-ant2506] should be installed upside down when installing inside a building, ie warehouse.
When I go to the hardware installation page for the antenna, Cisco makes no statement regarding this....they clearly show the antenna with the metal end at the bottom, not top.
http://www.cisco.com/en/US/docs/wireless/antenna/installation/guide/ant2506.html
Ultimately does it really matter which end is up if you are mounting inside? Just as long as it's vertical correct?

You are right.... as long as they are verticle you should not have any issues. The reason why they might ask you to face it downward is due to code in some area's..... code sometimes states that there will not be any objects facing upward.... just in case someone falls. So it is more of a safety aspect.

Cisco AIR-ANT2506

Hi everybody
I have a question about installing a wireless solution with the AIR-ANT2506 connected to the acces point 1242AG-A-K9 (LWAPP) and the goal is register the ap to the controller 2504.
This antenna is supported by the controller?
Thanks.

In general, the WLC does not care what type of antenna you use with the AP, so long as they can connect. The
AIR-ANT2506, is a RP-TNC connector which works on the 1242.
Keep in mind, that under the AP Radio config for 2.4, you'll want to specify the dBi values for the antenna, so that RRM can be calculated correctly.
HTH,
Steve

AIR-ANT2506 ... Can it be mounted up-side-down?

Hi,
Just wondering if I'd lose any signal strength if I was to mount the AIR-ANT2506 in the up-side-down position.
The reason I want to do this is that currently we have an AIR-ANT2506 mounted to the side of an outdoor enclosure, where it sits raised above the enclosure. But I feel that the enclosure is mounted a bit too high, so I thought about mounting the antenna in the 'hanging' position from the enclosure to lower the position of the antenna.
Can the AIR-ANT2506 be mounted in this way without any consequence?

Hi David,
The 2506 can be mounted in an inverted position but you do run the risk of it filling up with water if exposed to moisture;

AIR-ANT2506 External Antenna Coverage Range

I've got an AIR-ANT2506 external antenna mounted on the side of a metal building. Hand-held Teklogix scanners connect to the AP and scan material outside. What kind of coverage range can I expect from the AP? Also, what's the recommended height for the AP to be mounted?

I've got an AIR-ANT2506 external antenna mounted on the side of a metal building.
Oh nuts. This is not gonna sound good.
The ANT2506 is a 2.4Ghz omni-directional antenna. If you point the antenna to your face, for instance, the signal is a near perfect circle, however, pair this with "the side of a metal building" and you've just literally turned an omni-directional antenna to a directional antenna.
Also, what's the recommended height for the AP to be mounted?
Maximum height is 10 feet. Make sure your antenna has clear line-of-sight. Any metalic or concrete obstruction can disperse the wireless signal.

Does AIR-ANT2506 Ship with A Mast Mounting Kit?

Does the antenna ship with a Mast Mounting Kit or does that have to be ordered separately? If a separate kit is required, what's the part number?

It comes with one.... take a look at the one that it comes with and see if that will work for you.

If you need something different, Sparco Technologies can custom make a mount for you. They also have different type of mounts.

AIR-ANT2451NV-R

Hi guys,
I have another question about the AIR-ANT2451NV-R antenna: is it compatible with the Aironet 1250?
In the documentation for the antenna it says:
“This antenna is designed for indoor use with any Cisco Aironet 802.11N radio device that uses a RP-TNC connector.”
But the ANT2451NV-R is not listed in the Aironet’s 1250’s supported antenna list :
AIR-ANT5959
AIR-ANT2422DG-R
AIR-ANT4941
AIR-ANT2430V-R
AIR-ANT1728
AIR-ANT2506

This document outlines the specifications for the AIR-ANT2451NV-R dual band MIMO low profile ceilng mount antenna and provides instructions for mounting it. The antenna operates in the 2.4- and 5-GHz frequency ranges and is designed for indoor use.
Yes. That's the reason why this model has six (6) pig-tails. It's in the release notes of the IOS.

Wall mount bracket for AIR-ANT5160V-R

Hi all,
I am looking for a wall mount bracket reference, for these 2 models of antennas :
- AIR-ANT5160V-R
- AIR-ANT2506
Something like that :
I was not able to find any reference in cisco product list. Does anyone have an idea ?
Thank you

Hi Scott,
Thanks for your reply.
The picture I am showing is an example of what I have seen.
I am going to deploy lots of wireless sites, that's why I am looking for a reference of wall mount bracket I could buy to deploy easily the outdoor antennas.
It seems this accessory is not part of Cisco's product list ?

Wireless bridge design for 3 buildings

Hey all, I need some assistance picking hardware for the following:
Site A is the main office. Site B is about 500 yards away, direct line of sight, and will only connect to Site A. Site C is about 100 yards away, direct line of sight, and will only connect to Site A. All buildings are single story, and I have full access to rooftops to mount anything.
I was thinking (3) Aironet 1300's, but I've only ever deployed access points for end users, not for point to point bridging.
Which antenna's do I want to use? Two antennas at Site A, or is there a multipoint antenna that I can use? Any issue with placing the AP's inside the buildings and running cable out to the antennas? Aironet 1300's support this type of config?
Thanks!

So I want:
(3) AIR-BR1310G-A-K9-R - Cisco Aironet 1300 Series Outdoor Access Point or Bridge with RP-TNC type connector.
(3) AIR-ACCRMK1300= - Roof Mount Kit.
(1) AIR-ANT2506 - Cisco Aironet 2.4-GHz, 5.2-dBi omnidirectional mast-mount antenna.
(2) AIR-ANT2410Y-R - Cisco Aironet 2.4-GHz , 10-dBi Yagi antenna.
And just to clarify, the connections look like this:
Wall Power -> Power Module -> Power Injector -> Dual Coax to Ground Block -> Dual Coax to AP -> AP to antenna.
AP mounts directly on mast with antenna?
Looks like the roof mount kit includes everything I would need, as long as the power injector is within 50 feet of the ground block, and the ground block is within 20 feet of the AP.
Does this all sound correct?
I appreciate the help!

NCS antenna and RF prediction problem

so...
we bought a bunch of cisco 3600 series aps with external antennas
went to http://www.cisco.com/en/US/prod/collateral/wireless/ps5678/ps11983/data_sheet_c78-686782.html
followed the link 802.11n antennas
and choosed the right antenna for our purposes 5dbi omnidirectional 2.4Ghz only
the selection is AIR-ANT2506 3x AP
mounted the access points
connected to the wlc 5508
Then opened Ncs and created a new campus and a new map
positioned aps and...
result? the AIR-ANT2506 is not in the list so the only option is to chose "other"
and .... BAM
Ncs refuses to predict RF coverage cause the antenna is set to "other" and thus not compatible....
THIS IS BAD

Most likely TAC will tell you that your antenna is not supported in the 3600 since the AP requires dual band antennas and the 2506 is 2.4Ghz only.
I would suspect that the 2506 would be supported on a 3500 series access point in NCS since it does not use dual band RP-TNC. The use of that particular antenna with a 3600 seems very odd and possibly a poor choice for that AP. If that antenna is a requirement, RMA your 3600 and save some money and a headache with the 3500.

Why does the Antenna range differ a lot between 1728 and 2506

Hello,
I'm wondering about the documented approximate range of these two Cisco antennas, that differ a lot.
Can someone explain the big difference in range between these two antennas that have both the same antenna gain of 5.2 dBi and beam width 360Â°H and 38Â° V
AIR-ANT1728 Indoor antenna
Indoor range at 54 Mbps: 114ft, 35meters
AIR-ANT2506 Outdoor antenna
Range at 54 Mbps: 0.21miles, 340meters
Can we use the 2506 also for Indoor applications ?
Please advise and explain.
Thank You in advance.
Winfried

I would assume that the outdoor range is measured in free air ie with no obstacles where the indoor range is indoors and takes account of walls etc.
I may have seen something on the test methodology but it may have related to clients rather than antennas.
The 2506 is fine indoors as it says in the installation document
https://www.cisco.com/en/US/docs/wireless/antenna/installation/guide/ant2506.html
However the range will be the same as the 1728 as the RF characteristics are the very similar.

External Antenna for N Series 1252

Hello All,
Can someone please let me know which externally mounted antenna is the correct part to use with a AIR-AP1252 N-Series, (6dBm gain or more, its to cover a playing field)
I've been scouring the Cisco web site for days to find a definative answer and am getting confused.
Ideally it needs to cover both radio bands but if it only does 2.4Ghz, I'll settle for that as my life is ticking away.
Any idea on the wall mounts too.
All help appreciated
Regards Tony

Keep in mind that you can use any 2.4GHz antenna on the 1252. Some antennas have three cables for convenience, but in reality there are three individual antennas inside the casing. You can attain the same effect by purchasing three of the same kind of antenna and connecting them to the 1252.
The AIR-ANT2506 is a good outdoor antenna and would be fine for use with clients as long as it's installed close to the ground. Omnidirectional antennas are quite deceptive in how they work - they actually form a donut-type coverage that gets "squashed" as gain is increased. A 5.2dBm isn't too bad, but if you install it too high then the signal will go right over the heads of the users. I guess I mention all that to say that you shouldn't install it on a 20-foot pole on top of a roof. :)
To take full advantage of 802.11n, you'll need three antennas. Otherwise, one or two would suffice fine if you're in an 802.11g environment.

1252 AP - Bridge Mode

Hi there,
We have two buildings that are about 80 meters between them, in line of sight.
The point-to-point link will transfer from "building A" a file about 0.5 GB for every 30 minutes to a server in "building B". I thought to use two 1252 in bridge mode to take advantage of the N standard's data rate in this short range (1300 or 1400 for long range and only G standard) with the 2.4 GHz band.
1) Do you agree with me on the choice of the AP?
2) If so, what kind of antenna should I use to take advantage of MIMO, omni like "Rubber Duck" or directional Yagi and Patch?
3) I have seen these models to serve 2.4 GHz -> ANT24120 AIR-, AIR-ANT2410Y-R, AIR-ANT2506, AIR-ANT2460NP-R, which do you recommend?
4) I'd use all three antennas for MIMO, one or two would not be enough, and I would not have enough data rates, right?
5) I do not have PoE switch, is there any advantage of using Cisco power supply or the Power Injector like AIR-PWRINJ4, in terms of loss?
6) If I install the APs outside, there is some original housing from Cisco?
7) If I install the APs inside, a cable as CAB020LL-AIR-A would give a significant loss on the data rate?
Thanks for your support.
Regards

Andrea,
the AP itself should be fine, the only thing is it goes End Of Sale 1/30/2012.
For the antenna, I would tend to want a patch, like AIR-ANT5160NP-R=, vs an omni, due to the distance you are needing to shoot the signal. WIth that in mind, if you can use the 5GHz, you can then do a 40MHz channel, and get increased throughput, if you are using all three of leads on the above antenna.
There is an similar antenna for the 2.4GHz if you can't use 5.
The AP itself would need to go in an enclosure, I'd look at terrawave for one if you needed to mount the AP outside. But, you should be able to mount the AP inside, and use the Low Latence LMR (CAB020LL), to extend the antennas outside the building, while leaving the AP protected.
HTH,
Steve
