I have a stereo in my cabin that is currently attached to a $8 rubber coated antenna from Wal-Mart, which doesn't get very good reception.

I was wondering if anyone has ever tried or had any opinion regarding using the mast as an antenna?

Would it be as simple as bolting a wire to the mast and splicing into the Antenna wire?

Also is there any reason why I couldn't or shouldn't splice my stereo antenna into my VHF antenna?

Hi Carlos,

I think the mast is made of alumimin which is not a great conductor of electricity. You could try just taking a piece of wire and touch it to the radio's antenna input and then to the mast and see what you get for reception.

Do not splice into your marine radio antenna. As soon as you transmit, you will blow out your stereo receiver.

Carlos, I assume you are listening to FM radio. If so, the problem with using the mast is that it is not the correct length. FM radio antennas need to be a certain length, about 3', IRRC. A proper antenna for FM is not very expensive. Perhaps your antenna could be mounted on top of the mast for better reception, although in SoCal, I can't imagine that you can't get great reception of a couple dozen stations with very little antenna.

If you are concerned with AM radio, the mast should work just fine.

Gentlemen;
The mast and rigging on boats is--or should be-- groun ded back to the water. When you get a lightening strike or if it is just static charge leakage, all the rigging should be tied together electrically. It is not to much of a problem in So. Cal. because there are few thunder and lightening storms. Here in Texas and the mid west they are the rule of the day for most rain that we get comes in thunder storms. A friend at our yacht club found that he had been hit by lightening because fittings were lightly welded together at their points of contact. Very strange, no other boats in the yard seem to have had that problem, his boat, with others, was store near trees; it was strange but most of us make sure that all our rigging is connected and to the keel. when sitting on a trailer it is insulated from ground, obviously, so we're not sure why we don't get hit more than we do, but do not use your mast for an antenna. And as pointed out above, if it is FM you need a dipole type for best results.
For what it's worth, Al Ge

I have something like a 6' length of antenna cable strung under the cockpit seats with no antenna attached and I get local S.F. stations with no trouble at all. You may want to try something like that.

I have a rubber coated whip FM antenna mounted to the corner of the transom on the engine side. It works great and never gets in my way. It came with the boat but I don't think they're too expensive.
