Yeehaw... First post and this is right up my alley.
Long time lurker here but reason to chat now as I am doing the same thing.
I'm using this for the 2 wifi channels.
Sunhans Dual antenna WiFi Signal Booster 1000mW 2.4 GHz 2T2R / 300Mbps Amplifier
And this for the 5.8 (just because I got it cheap from DBS)
2016 Sunhans eSunRc 2W 5.8GHz mini-Wifi Signal Booster, 1-3 day shipping
1watt each for the wifi, and 2watts for the control signal
I will be seeing pretty soon what gains this will get me. I have already made almost 3 miles with just the panel alone (along the beach , no interference)
Now just looking for simple, reliable, small, rechargeable, strong battery to power it. Nothing big, just needs to last through a morning of flying maybe 4 or 5 batteries.
I feel like I'm getting retarded with this though and only adding stuff because I need more **** to do

. The Itelite panel already gets me out way farther than I am comfortable. But then I see some of the setups on here and get all tweaked
Battery mod next and who knows WHAT else right?
