This antenna does NOT include cabling. You must select a length of cable from the list (for the ultra-low-loss cabling, we bundle the connector you'll need to connect the cable to your adapter). If you already have a compatible cable you plan to use (this antenna has an N/Female connector), you may select the "I already have a cable" option at the bottom of the list.

How much cable should you use? Unless you plan on using an amplifier as well, we recommend using LESS THAN 50' OF CABLE to minimize signal loss. The longer the cable you use, the more signal you lose. Mounting the antenna outside and reasonably high up is recommended, but using long lengths of cable for the express purpose of mounting the antenna higher up is NOT worth it - you will lose more signal from the cable than you will gain from mounting it up higher. For example, using a 20' cable and mounting the antenna at the roof line would be better than using a 50' cable and running the antenna high up a pole on the roof.

So far so good. I got some real slow signal in the Shenandoah Mountains where I have never been able to get into my remote desktop before. The real test will be next month in the Adirondack Mountains.....fingers crossed.

Tried the T-mobile version of the signal booster, it didn't work. After spending quite a few hours "tweaking" modem/router setup I came across an external antenna setting that was enabled. This setting was not listed/shown in the router manual. Trying everything possible, I disabled this setting and my signal reception improved to the point where I no longer need the antenna. Now I still do get better reception with the Modem sitting outside on the window sill, but I can pretty much leave it inside the house for the most part. So never fails there is always some obscure setting that needs to be enabled or disabled to get things working.

Using this for T-Mobile wireless broadband. Was hoping this antenna would help improve my signal without having to place the actual modem out on the window sill. When I place modem outside on window sill I get great signal/speeds (without using the antenna), but once I move the modem inside the window & close the window I lose a significant amount of the signal, (with the antenna connected). Rather frustrating to say the least. Just trying to "carry" the outside signal reception to the inside. Have also tried the wilson exterior flat panel directional with limited success. I believe that I may be competing with 2 - different towers & the modem can't seem to lock on to either one, accept when it is sitting outside on the sill. (using the Netgear 340U modem). BTW - I have also tried the T-Mobile signal boosters setup they have, thumbs down on that idea. Any suggestions? Simply trying to get the same reception with modem inside hooked up to the Omni antenna as I do with modem sitting outside on the window sill with no antenna attached. pretty confusing huh? thanks. jim

Thank you very much! We got exactly the parts we needed, and so far, the omni booster has been a big help! Can’t wait to get to an area where we can try the directional booster as well. You made the process very easy.
