Wilson 50ohm Interior Panel Antenna - 311135

In Stock

Item Number: 603
Model: 311135



Check Router Compatibility

This antenna is for use as the interior rebroadcasting antenna in a wireless repeater setup. For use as a standalone antenna for a 3G or 4G modem or router, we recommend the 304452 model, which includes suction cups so that it can be mounted in a window facing the cell tower.

This high-quality 50ohm panel antenna is designed to use in cellular repeater setups as a rebroadcasting antenna. It is compatible with all frequencies currently used by U.S. and Canadian cellular carriers (and many worldwide carriers too). The Wilson Interior Panel Antenna has a built-in ground plane for versatile mounting with any 50ohm wireless amplifier system. It is a directional repeater antenna that can be mounted on a wall to aim horizontally at a specific area or aiming down from a ceiling for a more general rebroadcast.

The Wilson 311135 antenna can be used a replacement part for existing wireless repeater systems or as an add-on for a multi-antenna system. Note that it has not been weather-proofed and therefore is for indoor use only. All mounting hardware is included for installation. Wherever you mount your indoor panel antenna, make sure it is pointed away from the outdoor antenna to prevent interference and oscillation.

In March I purchased these products due to no service where we parked our motor home. Verizon Droid Razor phones and MiFi 4620. Phones from time to time 1x voice mail and some e-mail nothing for the MiFi 4620. With the Wilson products make and receive phone calls and MiFi 4620 three bars. We are south of Jourdanton, Texas twenty-three miles and louse 3 G service on the phones traveling south about six miles. Service varies with atmospheric and weather. Buster

The antenna made the difference in being able to receive Verizon 4gLite vs. just 3g. I am using the very short coax on the antenna and it is placed along with the modem and Cradlepoint MBR95 router near a window for good reception. I suggest a searching the site with just the modem and a laptop prior to the installation to enable the bast location.

The unit did not increase the data availability in my remote ranch. We are on the border of 3G and I get 3G with my phone. I had already installed a cell booster and it provides some improvement on the interior of the home. I did not notice any increase in the data signal with the antenna.

I use this antenna only as part of a repeater setup for my Verizon wireless data connection, with my USB modem rubber-banded directly to the front of it. It handles 3G and 4G signals equally well -- does everything I need.

This antenna boosted my signal about 7db. I am very happy with it!

The antenna is fantastic. It raised my RSS from 10 to 15 points and has given me very reliable service. There was 1 problem, though. In the description it stated that the antenna was designed to be mounted in the window facing out. When the antenna arrived it only had a flat wall mount and no instructions about mounting it in the window. I now have it taped in the window where it needs to be. This works well, but is a little bit less than elegant. Overall, though, I am very satisfied with the antenna. It is great! the shipping and delivery from 3G Store were nothing less than superb.

I ONLY gave it 3 stars, because the back mounting hardware is a joke. Its soft and will bend too easily. As for Performance I will have to give it a 5 star rating. We performed a live webcast from a remote beach on the island of Maui using the Pantech from Verizon. "normal" cell phone customers are lucky to get ANY 3G signal... we were running at 3/4 4G signal. 15Mbps on the donw and 13 on the up - stunning. Watch out for kincked cables though, they will kill you!

We will pass on your comments to Wilson. Glad that the product is a 5 star when it comes to performance - that is usually the key.

The antenna's performance at boosting DBI is good. The attachment hardware is very weak. It should be made out of steel, not aluminum.

I gave this one star because it didn't help get a better 4G signal. We're in a fringe area and I was hoping to be able to get 4G.

5Gstore Comments:
It depends how far out you are, it doesn't work in areas with zero signal, This is why we offer a 14 day return period which starts from delivery day.

If the Wilson 311135 antenna uses N Female, does that mean I need a cable with N Male connector?

Yes, that is correct. The N Female spec refers to the connector that is found on the end of the antenna, so you would need a cable with an N Male connector.
