Seen very expensive signal boosters and cannot see how to justify the price for local flying.
All im looking is local to where I live but I live in dense spot with hills and lakes not wanting to fly stupid distance just want keep control of my bird up to 2k away which cannot ATM.
I saw this claiming 16dbi and watch videos and seems to work better than the fitted manufacturer antennas
Seen these also 10dbi and wee bit more expensive both look similar.
