chuckySK Its becouse receive quality of signal is how in -dB when 0dB is direct connection between TX and RX with cable/also this connection have from -0,5 to -3dB lower signal/. dB is logarithm function... -60dB is much more greater signal than -90dB....3dB on log. scale is double....This 30dB signal boost is very very good....even the best omni antenas usable for RC have only 8-9dB...

I tried range tests with the booster in line, and then with just the antenna and the booster removed. With just the antenna I am seeing 90db With the booster as well I am seeing only 60db The booster is supplied with 5v and its blue LED is showing. This is not an amplifier it is an attenuator !!!! Very unimpressed with this - what a waste of money.
