Wrt54g with 2 external antennas?

I want to know if I can attach two external antennas to my wrt54g router. I have to cover two opposite areas from the building where I have my wrt54g router and instead of using an omnidirectional antenna I am thinking if I can use 2 sectorial antennas as they are cheaper than omnidirectional antennas and range covered are longer too.
Can I use two external antennas in my wrt54g router to cover two aerial sectors that do not overlap?
Thanks

not sure whether u can use more than one external antenna on the router....however if u need more help go through this links

Linksys WRT54G with Cisco Aironet antennas

Hi Cisco users,
I've got a small project:
I need to provide a wireless network from a farmhous to a piggery:
Distance about 40 metres, no obstructions
Equipment: Linksys WRT54G v3.1
When i place the wrt54g to the most far point of the house (towards the piggery) i get a fairly stable signal of around 11Mbps
I want to strengthen the signal via an external antenna, preferrably outdoor.
i'm thinking of this antenna:
Cisco Aironet 8.5-dBi Patch Antenna (AIR-ANT2485P-R)
http://www.cisco.com/en/US/docs/wireless/antenna/installation/guide/ant2485.html
or the same one as above only with 6 dBi.
http://www.cisco.com/en/US/docs/wireless/antenna/installation/guide/ant2460.html
Both the linksys and cisco aironet antenna's has RP-TNC connectors.
My questions:
1: Can cisco aironet antenna's work with a linksys wrt54G, based on the same connectors.
2: Is the antenna strong enough? can i cover a distance of 40/50 meters with this antenna, or with the 6dBi version?
3: it's a directional antenna. the piggery is straigh ahead of the farm house. How much beam width do i have on the end of the signal for coverage?
4: maybe i need an extension cable. is this the right one?
Cisco Aironet 5-ft, low-loss, 2.4-GHz RF cable with RP-TNC connectors (AIR-CAB005LL-R)
http://www.comegacity.com/networking-wireless-b-bn/antennas-cables/cisco-air-cab005ll-r-aironet-5-low-loss-cable
Thanks in advance.

The connector has to be the same but also the impedance. Cisco APs are at 50 ohms. Not sure about linksys ...
Otherwise if you put the antenna outdoor and there is no obstacle, 40/50m should be reached with those antennas. Take the lowest length of cable possible to put the antenna outdoor though as cable brings loss.
I can't comment about if the 6dbi will be enough as this would require experience with the same hardware which I don't have.

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.

Nokia 3315 with cradle and external antenna(car an...

I have an old 3315 and I use it on a boat with an external antenna to get a better calling range.
My old 3315 is now having repair problems and I want to buy (on eBay) a more modern phone but still use the cradle and external antenna. A problem with the 3315 is that they are becoming uncommon and the ones that are available have been well used and often have tech problems now.
I see that the 3310 has a similar shape and no doubt the cradle fits it also. I have the antenna on a long piece of coax cable and pull it up the mast on the sailboat to improve the reception.
Can anyone give me some help with this? The more modern I go the more features I get (eg mp3 player,radio reception) however I still want to retain the existing external antenna setup as it is great for camping and boating to stay in touch.
Thanks
Peter

Also, what is the length of the cable, and what is the model No of the cradle?
I have a 3310 and can test how well it works with your setup.

Problem on Cisco AP 1240AG and External Antenna

Hi all :
I am setting and configure the Cisco AP 1240AG with 5GHz External Antenna extension. The whole product is called iWap. The problem now is that the wireless signal amplitude only can reach 3 bars instaed of ful 5 bars.
Please help below few questions I have for this setup and configuration :
1. What is the default or original frequency of antenna of Cisco AP1240AG? Can a 5GHz antenna work with the AP 1240AG whereby it is run with 802.11a and 802.11g?
2. If 5GHz antenna can work with 802.11a or 802.11g, what is the setting or configuration needed to be done at the Cisco 1240AG? Or, no setting or configuration needed because it will automatically work by default?
Many Thanks in advance and best regards,
tangsuan

1240 is the product "line," 1242 is the specific model. The come in both G and AG variants. The link below is a picture of an AG variant (with both an 2.4 Ghz "A" radio and a 5 Ghz "G" radio). The two antenna ports on the top in the blow image are for the 5 Ghz radio, and there should be some blue text indicating as much.
http://www.cisco.com/en/US/prod/wireless/ps5678/ps6521/prod_large_photo0900aecd8031d92d.jpg
If you don't have the two antenna ports on top, and just have two near the ethernet and console ports, then you have a "G" model, which only have a 2.4 Ghz radio. See my pic below. G model on the left, AG on the right.

Usb wi fi external antenna

We live on a small (26') sailboat and are presently in a marina at Joe
Wheeler State Park in Alabama. Currently we are on the fringes of both
the verizon network and the marina wi fi. Very frustrating to sit on
the boat and not get either connection.
So. I am hunting for an antenna that I can mount outside and plug into the Verizon 760 and a
seperate one I can use for wi fi through USB. My mast is 34 ft. tall and the
spreaders are at about 20 ft. so would need about 20+ feet of wire. I
could mount them lower but it might get hung up in the sail.

Hi Harry and Barbara,
With an external antenna (if at all applicable), signal loss in the antenna cable could be considerable.
A plain USB cable extension has its limitations, too:
http://www.usb.org/about/faq/ans5
Alternatively, for the Wi-Fi part, you could possibly experiment with a method where a properly positioned wireless Ethernet bridge (also known as a gaming adapter) is used. The device would have to be made weather-proof to begin with. With Ethernet and low-voltage power cables connected, the unit should be able to act as a remote transceiver, thus allowing you to gain access to the local Wi-Fi network.
Examples:
http://homestore.cisco.com/en-us/adapters/linksys-WET610N_stcVVproductId65221232 VVcatId543809VVviewprod.htm?icid=All-Linksys-Products-Bridges&src2=home_linksys_ bridge_all
http://www.netgear.com/home/products/wireless-adapters/high-performance/WNCE2001 .aspx
For the mobile broadband, a mobile broadband router (with support for the USB modem stick in question) could make it easier to find a position with better reception. It might even be possible to, somehow, connect the wireless Ethernet bridge to the router.

To determine the required height of an antenna tower over a hypothetically flat, spherical Earth, it's necessary to calculate the effect of the Earth's curvature, and then add a distance equal to 60% of the radius of the First Fresnel Zone. The table below shows the result of these calculations. Values have been rounded up to the nearest foot.
Line of Sight Distance Between Antenna Towers
Height of Tower to Avoid Flat Earth Curvature
Tower Height Required Over Tallest Obstacle In Line-of-Sight to Provide
60% Fresnel Zone Clearance
2.4GHz 802.11b/g
5.8 GHz 802.11a

It can be seen in the table above that a wireless link between two points separated by 26 miles would require an antenna tower with a minimum height of 103 feet for an 802.11b/g radio and 95 feet for an 802.11a radio. In practice the heights would typically be 20 feet higher, or more. This is because the Earth is not smooth and flat and the tower height must be raised to compensate for buildings, trees, hills, or other obstacles. For example, in a suburban setting, with houses and small offices, it may be necessary to add 20 to 40 feet to the tower height to get over the homes, offices, and trees that would be in the line-of-sight between the two towers.

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.

Car Cradle for Charging and External Antenna Compatible with Tour

Is there a car kit that allows easy charging and connection to external antenna for the Tour? I had Comfort Cradles by Bury for my last two BlackBerrys, but I just was disappointed to learn that Bury does not have or even plan one for the Tour. Any suggestions? If I had known this before, I probably would have stayed with my 8830. Thanks.

To answer my own query - I just spoke to someone at Smoothtalker and was informed that Smoothtalker will be releasing a charging cradle, with external antenna conttection, for the "Tour" in "about a month."
I still would be interested in hearing from anyone else with any information concerning this.
Thank you,.

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.

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.

Treo 700P external antenna jack

I just recently purchased a Treo 700P and a external antenna adaptor, the adaptor does not fit my phone. When I was shopping for my phone I looked at a new Treo 700P at the Verizon store and saw that it had a external antenna jack. The jack on the new phone was much smaller than the one that is on my phone. Did Palm at some point in time change the dimensions of the external jack? My jack is gold colored and has the appearance of a mini rca jack with a center hole that takes a thick center conductor.

gjkozy, the fault is with the Vendor who sold you the phone and didn't give you a disk with it, not Palm's...
Palm supplies a disk with every new phone that is sold. Did the vendor lie to you when the phone was sold? Or was it listed as "Phone and charger Only"?
The disk cannot be downloaded for free due to the fact there are third-party, copywritten programs on each one. These are not "free for the taking" by anyone wanting to click on a download link.
There are dozens of free Solitaire games available on www.freewarepalm.com. There are lots of Voice Dial programs for sale on the internet. Instead of spending money for the old disk, why not just purchase an updated Voice dialing program?
BTW, I'm assuming you know that no PalmOS phone can Voice dial through a BlueTooth earpiece. It's a limitation of the OS. If that is the goal of getting Voice Dial software, save your money!
I'm sorry about the antenna problem, I have no suggestions for that.

External antenna or weather proof Airport Express

Does anyone have a solution for connecting an external antenna to an Airport device, be it an Express or Extreme via coax. With the insulation on my house having a metallic cladding the signal is attenuated significantly and outdoor reception is poor to non-existent (iPhone to iPad respectively). The other solution would be a weather proof box? or the like. Freezer bags don't make it.

solution for connecting an external antenna
Be sure to check with your HOA (Home Owners Association) first. Most HOAs restrict antennas in various ways.
Some HOAs do not allow any type of radio transmission.

External antenna needed --help!

My friend in the baja is sharing his connection w/ me but his router is in a concrete building, and my place is located about 100 feet from his place and am wondering what kind of external antenna would help me connect better? Here is the equipment he has! Where canI get one pronto???? Thanks
LINKSYS,BEFW11S4, IT TAKES AN,RP-TNC, CABLE CONNECTOR, IT HAS A SCREW CONNECTOR WITH A CENTER PIN

The Distance between you computer and router is around 100fts, i think if you are planning to buy an antenna i think it wont help you. Its better you go for a WRE54G, I think this will solve your Problem.
