hi there, new user.....
a friend helped me build a system using arduino nano and this transmitter and receivers:
my problem is the range, it just isn't enough. just a few meters and i need more.
the transmitter antenna is 1/4 wave length strait wire...
i would like to extend the range by replacing the transmitter and if need the receiver units.
taught of using something like this:
but i don't know if its compatible and how to actually connect it and make it work with my system.
would love your input and suggestions on what to use and how....
thank you very much,
