Why are handheld radios(FRS, CB, Amateur) antennas just one wire? How can that work to receive and transmit if it’s just one wire? I mean the antenna should be TWO wires, just like the antennas on the big stations, or the TV antennas. It should be a closed circuit((- and +) OR (- and ground)?).
That brings me to my next question:
I have a FRS radio. I used a TV antenna cable, and connected the radio wire to the inside wire of the cable. The cable goes up to my roof, which is only about 40 feet high, but did not work at all. If I go to the top of the roof with the radio on my hand the reception/transmission is great, HOW CAN I EXTEND THE SHORT FRS ANTENNA TO THE ROOF IN AN EFFECTIVE WAY, JUST LIKE IF I WAS UP ON THE ROOF WITH THE RADIO ON MY HAND???
