Yes it did and the 2 7dba square panel go on either side and the long one goes in the middle and looked on Amazon the same setup for the extender is about 65 bucks
Ha yip I try those back in 2019,slightly different on the model number but same thing .,



Yip they were cheap and get what you pay for,Those panels never change my issue and I ended up trying another cheap Argtec triple antennas which improved and work like stock should work,,out to 1km without no issues(far enough 4 me) ,,these panels non boosted unlike upmarket ones like Sunhams which have own power supply to actually amplify and boost or they hopeless
500ft pretty sad for a phantom,easy to open remote and check they plugged in correct plug,
Yeh sounds like your mate was trying to improve it aswell,,lots of Brands about ,maybe have look around at something in your budget and get something apart from the panels to try,,I'm sure you see improvement, panel might be ok for close activity but no good for any distance (that's my opinion)
Just add Itelite good trusted brand,,can get p3s kits,Had one on the p4 ,already did the Argtec on p3s or that would have got one too,,
Have look at Argtec sets and try find something like my triples , then you dont have to open remote,just screw them onto existing terminals on remote,,if you change kit you need to open remote and change antenna wires and mounting,it look like my remote with extra holes from previous attempts
