Cell Phone Booster with a twist

Interestingly enough, I used the Sleek before getting the great deal on the Wilson amp/antenna(100.00) and still in original packaging...looks brand new. Anyways, I was pretty happy with the Sleek operation but couldn't pass on the Wilson.

Guess I should have mentioned the antenna, it is one of the "trucker" type antenna's with the radial arms. So in my limited knowledge, that's a half way decent one. I kinda figured it would not be beneficial but thought it was worth a question anyways. Thank You all.

You are unlikely to gain any appreciable signal level due to the issues mentioned. A Yagi is a pain and may not actually help much. You really need a clear line of site for a yagi to help much.

Based on 40 yrs in the two way radio field I have found that a good Omni gain will often outperform a yagi when in real difficult terrain or foliage issues.

As an avid Rver and telecommunications technician I have experimented with many variations of antennas and amplifier. I was the first to make telephone calls in some extremely difficult places in California. Spending more hours than I can remember with different antennas, painters poles included, yagis, amps, etc., my opinion is you are going to spend some money on coax and antennas that just will not give you much improvement over a good Omni antenna with a Wilson Sleek.

Not knowing which type of antenna you have, the clamp on like thisTrucker mount or the magnetic type like this Mag mount might make some difference. I use the magnetic one and mount it on an 8" diameter piece of steel laying on top of the RV. I'm sure "height is might" but you may loose more than you can gain through a longer cable. Sometimes just moving the antenna a couple feet makes a difference. If I was really hard up I'd go with a Yagi like this Yagi directional Only drawback is you need a clear line of sight and know where the cell tower is.
Ha, looks like someone else was typing faster than me..:B

This is tricky. The big problem with antenna's is cable loss. Adding an add on cable will guarantee you about 1db loss for the connector itself. I believe the Wilson use LMR100 which is just under 4db loss per 10 feet of length. So if you have the stock little stubby antenna which claims about 3-4db gain, adding a 10 foot extension will add 4 db loss plus 1db loss for the connector, thus giving you less that what you started with before adding the extension.

I would recommend one of a few options to maximize signal:
1) get a higher gain antenna like the Wilson 311125 antenna, it will get you up to 6db gain, you can also get directional antennas that if you want to point it, can get you much higher gain. A Yagi antenna can deliver up to 25db real world gain, but only has about a 15 degree margin for aiming it right.
2) having a custom cable made with RG-58 or LMR195, it is under 2db loss per 10 Ft but is double the thickness.
3) cut your cable length as opposed to lengthen it, as long as you clear the roof of your rig with absolutely minimal length.
