TV Antenna

Post by Dimitri-2000X-Tampa »

I got my portable TV/DVD yesterday and now I'm contemplating what to do about an antenna. The FM radio was easy, a little wire that goes around the top of the head compartment gets fabulous reception in Tampa Bay.

But the TV antenna part is a bit more challenging.

First, have any of you folks ever tried adapting the VHF antenna for use as a TV antenna also? Perhaps a little coax cable with the right connectors on both sides would work. Not sure if VHF for radios and VHF for TV's is the same, anyone know?

Of course, I suppose that won't work for the UHF channels but I think most football games are on VHF.

The other idea is to spend some money (about 80 bucks) for one of these boatenna's that can hoist up a halyard. Of course, my VHF antenna is already on top of the mast so that is why that came to mind.

Anyone ever tried one of these?

I made one of those from copper tubing and stuff I had laying around and a 40 foot piece of Radio Shack 300 Ohm twin lead with a transformer at the TV end. I used twinlead because it's light weight, cheap and you can close the hatch on it. I think you can get it at Home Depot too. I haven't had a lot of time to evaluate my antenna. Compared to an unknown type of antenna that the sound people installed somewhere in the foam in the V berth overhead, my home made one doesn't seem to work a lot better.

One is described here:

I've never tried the VHF antenna on TV. I don't think you'd have very good luck on TV. TV uses a horizontally polarized signal for reduced noise while the VHF is going to be vertically polarized. That's aside from the fact that the VHF is a designed for a narrow frequency range that doesn't include the TV bands. You may have some luck using it on FM.

Hope this doesn't double post...here it is again. We chose the Triax brand antenna which is mounted near the mast head. We posted a mod last season....under electrical and lighting...seems like it was titled Mast Head ...etc. The Triax comes with a small amplifier which we placed inside the head, opposite our swivel mounted LCD TV which is on the salon side of the forward head wall. We also use a short 'jumper' cable which allows use while parked on road trips. The mount we chose allows 90-deg swivel to reduce road drag. We are pleased with the performance....now, if there was something of merit on the TV...
Take a look at the mod. 8) Tahoe Jack
