i have ts832 transmitter and a rs832 receiver. i tried to build a radio receiver to pick up radio signals from the ts832 transmitter,. i measured the ts832's antenna. it was 8.8 centimeters. so i cut a piece of copper wire 8.8 centimeters long. i connected the bottom of the copper wire to two other wires. 1 wire was connected to the black prong of a multimeter. the other wire was connected to the red prong of the multimeter. i set the multimeter to 200 milliamps. i don't think i got a signal. most of the time the multimeter read zero. sometimes the multimeter, read 0.1 or 0.2 or 4. it uses the 5.8 cm band. how do i build an antenna that can pick up a radio signal from this ts832?
