Default 2 antennas, 1 vhf radio

2 antennas, 1 vhf radio, Can you hook 1 radio to 2 antennas at once?

I don't think so. What you CAN do (and I did this before) is use an antenna switch to change which antenna you're using, rather than the typical use of the switch to run two different VHFs off one antenna. I had the primary 8' antenna and an 'emergency' antenna wired up that way. No reason you couldn't run two 8-footers through the switch that way.

It's called "co-phasing" have experimented with CB radio and Ham but not with VHF. Why would you want to do this ?

Yes, I did this on my Grady 2 years ago. The only reason I did was I liked the physical appearance. I bought the switch from Mount Pleasant Radio in Mount Pleasant Southy Carolina. It did not give me any more range or add to the performance of the vhf.

Buy a second VHF. Connect it to the second antenna. Power it from a different source than the first VHF.

Redundancy is a fine thing.... especially offshore.

phasing a couple of verticals was common in Ham Radio and a few folks like myself did it with CB radio. When you phase two antennas together you end up with a directional antenna, not a good thing on the water when your heading is changing all the time. You do end up with around 3 db of directional gain phasing two antennas together. Going from a 4 foot to an 8 foot VHF antenna gives you 3 db of omni coverage, a better choice.

This switch I purchased maintained independency between the antennas. If I had to do it over,OCNSLR makes a great point. Instead of buying a switch, I would buy a second radio.
