Can my transmitter and receiver share the same antenna ?
They both run on the same frequency.

Thanks in advance,
Mark

In Simplex mode yes, in full duplex mode not!

It's easy, when the Tx transmit the receiver is off, and when the RX is ON the TX is OFF, like a CB radio.

Not a good idea if they aren't designed for it.

In extreme cases, the transmitter can fry the receiver if you simply tie them together.

Two-way radios have special hardware to allow the TX and RX to share an antenna.
