Do any companies offer an exchange service so that I buy a modified remote with an upgraded antenna and send them my old one after I get theirs? That way I wouldnt have to be without one for 2 weeks?
Presumably you have a P4P since that's where you are posting this question. If that's true, try flying with 5.8ghz AUTO with a windsurfer on your antennas. You can get over 4miles, limited by battery. You must have LOS connection to get this distance, no trees or mountains between the RC and the craft. I really don't see any need to buy an antenna upgrade with P4P, unless you have a battery mod to get more flight time.
If you have a P4, or P4A, completely different story. Call Jake at Maxx UAV.
I have this set Amazon.com: SKYREAT Copper Parabolic Antenna Signal Range Booster for DJI Phantom 4/4 Pro/Phantom 3 Pro/Advanced/4k/ Inspire 1 Controller Transmitter Signal Extender (2 Pcs): Electronics
and it helps a little but I cant get more than 6500ft in my neighborhood.
So is there a company that sells pre-modified remotes out there?
That does sound like a nice setupI met a guy awhile back where I flew. He moded his Phantom, and would stick antenna's on his car's roof and sit in his car while he flew. Seems super luxurious to me, and as time has gone by, I've become more jealous of his set up.
