hi
i'm just new to this field and i need some help on it and i appreciate
any help...
my aim is to make a 315 or 433 transmitter and receiver so what ics is
the best for that and where can i buy them and so for the antennas(but i
would like to build them)...
thanks-


For the antenna use a piece of wire, a length of lamda/4 is fine.

w.

is it a straight wire or curved ? shouldn't i look at it's impedance and
make matching with it ?
what about it's ICs




Use lots of ICs. It doesn't matter which ones. Just put a lot in.
