Testing VHF antenna with ohm meter
"Vinny" wrote in message . .. Hello, I suspect that my VHF antenna is shot, I think it's open circuit. I'm looking for a quick and easy way to verify it with an ohm meter. I know that the 50 ohm impedance is an AC impedance at RF frequencies. But I'm guessing a DC ohm meter should measure something between a few 10s of ohms to a few hundreds of ohms if the antenna was good. I'm measuring ~ 10 meg ohms. Time for a new antenna? Depending on the design, the VHF antennas that I'm familiar with will read either "open" or "shorted" with an Ohmmeter. 10 megohms is a strange reading for an antenna. Almost sounds like one that is supposed to read "open" but has a little (or a lot) of water/corrosion someplace where it doesn't do any good at all. Old Chief Lynn, W7LTQ |
