Testing VHF antenna with 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?

This will mesure the power that go's and gets back to your transmitter. -- Geert Maene. |
