So +11dB gain sounds about right and the construction is decent considering the price.

Overall I give it 4 stars for providing just the necessities required to boost your signal modestly at a decent price point, and I thank them for it

The booster package is a decent price compared to other boosters that charge a premium just to have multiple bands/ frequency's with the hardware

This was purchased to help improve reception on our local P25 Simulcast System.

This thing considerably boosted my reception.

got excellent reception boost for my drone operating at 915mhz

This booster really works

The booster worked very good after I aimed antenna to a T Mobile tower

The only down side is that it took me three tries to get the right booster, even with the advise from customer service

This thing considerably boosted my reception.

So just to clear things up, this is very much a 4G Band 4 LTE setup

So +11dB gain sounds about right and the construction is decent considering the price.

Construction is good, but at these frequencies RG58 pigtail should be a better class of cable.

Solved my problem as I can aim at just one tower and receive a single strong clear signal that overrides the other two.

First is whether this booster has the right frequency band that your phone mainly connects to, Mine is band 4 1700/2100 MHz, on the Metro/T-mobile Towers, make certain you get the right equipment/booster for your signal, you can check via app 'LTE Discovery"

You need to be sure what frequencies and band you service is working on and exactly where the nearest cell tower is that they are transmitting from

This antenna is an excellent performer, with excellent directional performance demonstrated in use with a scanner receiving an APCO 25 digital regional simulcast trunking system

I tried it for a week and found that my old Radio Shack center-loaded portable whip has better performance.

The rest of the install went smooth, and it works as advertised.

Worked as described

worked great and very directive..

Overall I give it 4 stars for providing just the necessities required to boost your signal modestly at a decent price point, and I thank them for it

Either I bought the wrong product or installed it incorrectly.

its definitely directional but very good, not the best quality but hard to beat for the price....great product
