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.

Cisco 1300 Series with AIR-ANT24120 external antenna

Here,
I am using Cisco 1300 Outdoor Access Point/Bridge. I connect AIR-ANT24120 omni antenna to the Right Primary connector but i'm not sure whether the AIR-ANT24120 is working or not because i find no difference in range before and after i deploy my AIR-ANT24120. Please could anyone confirm the working configure for this AIR-ANT24120 on my case. The 1300 Access Poiny/Bridge running C1310 Software Version 12.3(8) JA2.

Thanks for the advice. Things now is much clear now. i am connecting a client to the 1310. For a bridge link i can definetly associate from few kilometers away. But i was thinking that it is also possible to associate from few kilometer away using my labtop also. In orther words i am trying to connect a client to the 1310. Please if you have additional words on this, please i am really appreciate that co's i am sure it would help clarify more on this issue. Especially the limitation of clients or how far can i connect my client to the 1310, Or are there any special configuration on the 1310 plus my 12 dbi omni external antenna attach to it that would increase the range for my clients or is it only 100M-200M the maximum range for client irregardless of the external high gain antenna and all.
thanks.

External Antenna Mount for AIR-ANT5160NP-R

I about to embark on a project to create a wireless bridge using a pair of Cisco Aironet 1252's, which will be mounted internally, and a pair of Cisco Aironet 5-GHz MIMO 6-dBi Patch Antenna (AIR-ANT5160NP-R), which will be mounted externally.
Could anyone suggest the best way to mount the antenna? Both will be mounted to steel upper wall of the building (its brick below this). I couldn't find any specific mounting kits.

My bad on the metal wall mounting, it was late and I was tired.
Now that I have slept some here is what I am thinking. Why use the MIMO patch antenna? On such a short link you can use an omni stick. Then mount this to a wall mount antenna bracket such as this - http://www.google.com/products/catalog?q=wall+mount+antenna+brackets&oe=utf-8&rls=org.mozilla:en-US:official&client=firefox-a&um=1&ie=UTF-8&cid=6140961992914474386&ei=NCXlTKHiIYKglAfVw6XjCw&sa=X&oi=product_catalog_result&ct=result&resnum=1&ved=0CC8Q8wIwAA#
You would only need one bracket for each location and can secure the bracket to the metal wall with either large self tapping screws or using butterfly bolts.
If you are worried about your signal propogation then make sure your link is encrypted with AES and that your power is at minimum to establish the 54M link.
I would use the AIR-ANT5160V-R antenna.

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.

External antenna to extend the range of an Airport Extreme 802.11g

What is the best external antenna for extending the range of my Airport Extreme? My studio is in an old metal building and I want to send the single to my house which is about 50' away. The metal blocks the signal so I believe I need some kind of directional antenna. Any advise?

Here are a few you can check out ...

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.

AP1240 with AIR-ANT2566P4W-R antenna

Hi guys,
Would you use AIR-ANT2566P4W-R antenna with AP 1240? This AP supports 802.11a/g and has 4 external antenna ports (2ports for 2.4GHz and 2 for 5GHz band).
Ant2566 is for dual-band AP...
For me it looks like not the best practice, but to buy two single band directional antennas is not a cost efficient solution.

Hi,
If this AP supports dual band ? The 1242AG access point supports a wide range of antennas that you can connect to the RP-TNC connectors on the 2.4-GHz and 5-GHz radios.
I think you can use this antena(AIR-ANT2566P4W).

802.11N external antenna configuration

Newbie question.
I want to deploy a WAP with an outside antenna to improve my range. After a few hours googling and reading,
can I ask some questions.
It seems that I will need an 1250 WAP, which requires 3 antennas to work correctly.
Trawling the Cicso antenna options, the only 2 that seem relevant are the AIR-ANT1728, which says it is inside/outside,
and the more promising AIR-ANT2506 which is a mast mount option. Unfortunately, they do not offer an outside mulitple
antenna mounting kit.
So if I have to fabricate something.... what sort of configuration do I use. I have checked out some of the hobbyist
web sites and there are some "spectacular" designs ;-)
Do I have to have all of the antennas in a row ? Or it does not matter.
Is the spacing between the antennas important ? If so .. what are the measurements ?
The antennas offered by Cisco have short "pigtails". So if mounting outside, I will have to use a cable
extension. How do I waterproof the join ? One of the installation guides "helpfully" mentions some
coaxial sealant. Just looks like some sort of "silastic" to me.
Your thoughts. ?
TIA
Peter

What we've done is mount the AP and antennae units higher than the cable run. That way moisture won't go UP the AP or antennae enclosures. You can also get weather enclosures to protect either the AP or antennae (or both separately).

External antennas and gain settings

Cisco AIR-AP1242AG-E-K9.
In the web interface, if one goes to:
Network Interfaces/Radio0-802.11G/Setting tab
half way down the page there's a section called External Antenna Configuration and you can enter an Antenna Gain in the box.
The access point came originally with two small plastic antennas, about 6 inches long but I took these off and connected two external antennas, one is 3db, the other 6db. Should I enter 6db in the box or does the access point set the gain automatically? At the moment all antenna settings are at default.

In the case of a Dish, yes, it would absolutely impact your throughput.
It would be better to put the dish on one port and disable the other port.
The dual ports are for diversity; in an inside environment, having two antennas a small distance apart reduces the effects of "multipath" and "nulls" ... multipath is when there are several images of the same transmission (from multiple reflections), nulls occur when you combine a series of waves (like a primary wave and a near reflection) and the combined waves, added together, result a greatly diminished signal (like a "plus" 35 meeting a "minus" 35 ... the result is a null, or no signal).
For point-to-point, or point-to-multipoint diversity is generally not desired or needed.
The way the antennas are used does not permit efficient operation for coverage of more than one specific area.
Good Luck

When I use a GSI external antenna for WiFi I first get a message that "Firefox is already running but not responding etc", and then Firefox crashes. Can anyone help please?

Because of weak WiFi signal I need to use an external antenna (GSI USB wireless WIFI long range network adapter). My computer can see the signal clearly and shows that I am connected to the right network. But when I try to launch Firefox I get a message that "Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system." When I click "OK" Firefox tries to load websites but gives up and reports "Problem Loading". It looks like Firefox is having trouble "seeing" the signal from the external antenna. What do I need to do please?

Try Ubuntu support, I don't think your problem is with Firefox - it will use the connection that the Operating System "makes". I'm a real noob with Ubuntu myself, and don't think I can help you figure out the problem.

Has anyone had any success with an external antenna on a UMW190?

Although I am getting good service from my UMW190 without an external antenna, I am in a low signal area and would like to have rock solid coverage.
I have tried a 1900Mhz yagi, a blade antenna, an omni, and a grid antenna. I am not seeing any difference in signal strength at all regardless of whether or not an antenna is connected and which way it is pointed. I have also tried two different pigtails form two different sources, and even borrowed a second UMW190 and tried it, all with no success. I know exactly where the tower serving my house is located, but I did try each of the directional antennas in a full 360 degree circle, stopping every few degrees to see if the RSSI improved. I tried both polarities too, although I understand it should be vertical.
When I contacted Verizon customer support they had very little information about it. I contacted Pantech, and they told me that support for this device is now handled by UTstarcom. UTStarcom told me that support for this device is now handled by Personal Communication Devices. When I contacted them the response was (and I quote) "We don't have any information on any external antenna support of our devices".
So I throw myself on the mercy of the Gurus here in the forum.
Am I missing something obvious? Is there a command that "activates" the external antenna connector? Does the connector even have anything connected to it inside the modem?
Any guidance on this would be greatly appreciated!
-Rick

Usually the external antenna works best where service is obstructed by certain materials and the external antenna is placed in a different area . If the signal is steady for the external antenna and the UMW190 in the area where you are using the devices, that would be the general signal strength of that area.

External Antenna for WRT300N

I have the WRT300N Router and want to install an external antenna to increase my range. I cannot find a method of unscrewing one of the three existing antennas so I can hook up the extending cable. Do I have to break open the case and hardwire it? What connector should I use to solder onto the Router? Uncle Dannie

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.

The 1310's either have an external antenna connector or an integrated antenna. They don't have both.
The part number AIR-BR1310G-x-K9-R requires and external antenna. AIR-BR1310G-x-K9 has the integrated antenna.

Cisco 1941W - with external antenna cable

Hello guys!
I would like to ask, maybe you know or maybe you have tried to use these cables from Cisco :
Feature AIR-CAB020LL-R AIR-CAB050LL-R AIR-CAB100ULL-R AIR-CAB150ULL-R
Cable Length
20 ft (6 m)
50 ft (15 m)
100 ft (30 m)
150 ft (46 m)
Transmission Loss
1.3 dB
3.4 dB
4.4 dB
6.6 dB
for Cisco 1941W router with external antennas?

How far are you trying to extend the antennas? Those will work to reduce the attenuation if trying to extend the placement of the antennas. Basically they are LMR cables.
