RF range problem

[Ron Marcus]

What modules are you using?

[George]

LINX 418-LR modules - i ended up running three diodes to the supply of the RX module to drop the voltage - also have a 4.7 Tant to help level supply. The thing works great - I can get 300m now line of sight with just a couple bits of wire for an aerial. I have a 1/4 wave with a very small ground plane on the TX and a full wave with no ground plane on the RX
