One may also ask, How do you use a SWR meter?

In like manner, How do I test a VHF radio output? Remove the connector on the antenna cable from the back of your radio.

How do I test a VHF antenna with a multimeter?

Touch one lead of the multimeter to the metal part of the antenna and touch the other lead to the metal core of the cable. The ohms reading should be zero. If the resistance is greater than that, the antenna or cable is damaged, which is preventing a signal from reaching the reception device.
