VHF antenna connection

[chris-s]

I am fitting a vhf radio to the boat this winter and have purchased a Banten whip antenna. After fitting the cable to it earlier today, I thought I’d do a continuity check with the multimeter and was surprised to find continuity between the whip and the base with nothing connected to the other end. I removed the cable and checked the antenna itself and it still showed the same reading on the meter.

Took it back home for a closer look just in case there something stuck up inside but it all looks clear to me.

Have I misunderstood this?

Thanks

Chris

It might be capacitance coupled - in which case you won't see DC connectivity.

Probably fine.
There are often components a bit like a transformer connecting the socket to the actual aerial, so tests at DC are of very limited use.

If you get stuck, drop Tony Brooks a line - he is very generous with his help.

It's OK probably fitted with inductive coupler.
