Seems there are a number of threads that amplifiers are being discussed. When I get the chance, I'll try to update this thread with links to helpful info in other threads. Of course there is the "More Powerful Repeater" monster thread, that does have good info in it, but is too large and really focuses more on antennas and / or replacing the repeater. viewtopic.php?f=7&t=3880 There is also the "Phantom Vision WIFI" thread focused on talk of amplifying the P2V (quad). viewtopic.php?f=7&t=7448 There is the "Controller modifications" thread where some talk of modifying the controller with battery power for amplifiers. viewtopic.php?f=7&t=8652 The three categories to cover are (will add links to amp options, but don't want to be prejudice towards any one supplier or brand): 1) Amplifying the P2V (quad) WIFI (2.4ghz) (believed to be MIMO). 2) Amplifying the repeater (range extender) WIFI (2.4ghz) (believed to be MIMO). 3) Amplifying the controller (5.8ghz).
