[QUOTE="Brojon, post: 59302, member: 11898"] I've actually tested some of the parabolics with mixed results. I have one for my Phantom 4 that actually gives me consistently better range - maybe another 500-800 feet through trees and such. I have yet to find one for the Mavic that doesn't actually *hurt* performance. The Phantoms have a much larger remote and as such the antennas are literally twice as long as the Mavic or Spark's antenna and I suspect this is the reason for them being more amenable to parabolic focusing. Now just to clarify I'm not saying boosted planar antennas are junk - what I said was not one of these people are willing to provide test results. Without test results you have no idea what you're buying nor any clue whether any effort was made to optimize their operation. The thing that concerns me is that if the mismatch between the internal transmitter and antenna is severe enough it can damage the transmitter. Poor design can also result in spurious emissions outside the band which reduces your power and causes interference. They may well help somewhat but I'm *very* skeptical of the extreme claims - remember Dji claims much greater range than they can actually deliver too ;) Marketing y'all. [/QUOTE]
