It may be the ant. if so, it is probably located at the top of the mast (at least mine is and a buddy of mine has his at the top of the mast as well).
It may also be the wire or connection at the back of the unit. I replaced the piece of coax that runs to the ant. It was surfaced mounted in some areas where I have stowed things on top of the wire and over time this wore thru the wire, so i just bought a new piece of RG-6 quad shielded coax and some new compression fitted (not crimp on) F-connectors and hooked up the new wire. It solved the problem.
You could also get rid of the VHF unit and buy a handheld unit. I got one from my father about 3 months ago and I do not seem to ever use the unit on the boat anymore, always on the handheld.

Pura Vida,
Zach

Also check your through-deck connection and fitting under the antenna. They may badly corroded or broken.

The typical thru-deck bulkhead connector is a frequent cause of signal loss. I switched to a 'Cable Clam", and moved the threaded coax junction below decks. A true fanatic would have a single unbroken run from antenna to radio. (And when that fanatic needs help stepping or unstepping his mast, I'm going to be somewhere else.)

Wow. The cable clam is such a wonderful thing; I put one on my boat last spring. Do these fanatics still exist on such a small boat that is designed to have its mast raised and lowered on a regular basis?

Running new coax through the cabin was a royal pain in arse. That's when I realized how small a 25' sail boat actually is. I would NOT want to undo that every time the mast came down.

I did what Leon did using Ancor Wire Seals(pg.557 in the West Marine 2006 catalog)at the mast and deck for all my wiring and VHF cable.Easy, cheap and no more pin connectors!Connections are in a junction box above the head.
