Default Testing VHF antenna with ohm meter

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



Why do you suspect the antenna is shot?

Are you measuring at the end of 70 feet of coax attached to the antenna
or directly at the antenna terminals?

Try to get a SWR meter. This will mesure the power that go's and gets
back to your transmitter.
