View Full Version : Advice on transmission method

Hi everybody. I need advice on which transmission method to consider before investing.
I live in a remote area ( no telephone comm.). I need to control a relay distant about 1.5km.,
without line of sight due to heavy vegetation. It will be MCU for some security.
Can anyone recommend whether to use FM, RF or whatever. Antenna? Yagi? or other light weight.
Thanks for responses.

Whats your budget for this solution. Because 1 km no line of sight will get expensive.

I really donīt have any budget. I do have some FM and RF circuits but I would like to know in what direction to go.
I wouldnīt like buying or building anything unless there is reasonable hope that my circuit will work.
Any suggestions; Thanks.
