Default Testing VHF antenna with ohm meter

Vinny wrote:
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?



Thanks in advance,

Vin


Don't mess around with meters. If you are near a chandlers, buy an emergency
antenna. Try it out, if that does the trick, take it back and exchange it
for a permanent antenna. Any chandlers will oblige. Problem solved!
