Default Grounding the Antenna?

A blowboat know-it-all was saying that I must run a ground wire to the SS base of my radio antenna.

I had never heard of this being necessary for VHF. Was he referrring to the Single Side Band radios? Is it necessary at all? I wish Thom was here -- he'd know.

No you dont have to ground the base for a VHF radio. It doesnt take Thom to know that either.

In Thom's absence - here's the poop on grounding your VHF antenna. If your PL-259 antenna cable connector is installed properly (the PL-259 connector is the metal connector on the end of your antenna cable that screws onto the back of your radio) then the grounding wire that's in the antenna cable will be grounded to the frame on the VHF radio In 99% of installations that is all the grounding that is necessary in todays VHF radios. If you want to carry grounding one step further you can ground the radio's frame to what we call "earth," that is, you run a small grounding wire to the water thru a grounding plate, a thru hull fitting, a transom mounting bolt on your outboard, and a few others - but remember it's not necessary on most of todays VHF radios.

Blow-boaters are a little more concerned with grounding electrical items on their boats because of that big lightning rod they have sticking up towards the sky - and it is often important on a blow-boat to ground their radios. And FYI when the lightning starts, somethimes getting up close and personal to a blow-boater can have it's advantages in getting underneath their "umbrella of protection."

Yes, what all of above have said, HOWEVER, I have seen problems with UN-Grounded VHF antenna's, new ones and old ones. Ussually it is an RF problem (noise to or from other devices). But this is VERY rare and you'll know it when it happends.
