18% OFF 2.4G 2W Radio Signal Booster & Antenna & Feeder For DJI Phantom Multirotor TX Extend Range 33,20€ 40,59€ View It

Overall:

BG557213862 11/06/2017

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.

padcom Be aware that some units are broken and the SWR skyrockets making it dangerous for your transmitter! Best measure the SWR (for example using Taranis radio or using a regular SWR meter) to see if you have a working unit

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...
