I know, I know, you're not supposed to be watching TV BUT sur is nice for the games on a rainy day. My question is I am thinking of installing a 17" flat screen but I am on a mooring and have two batteries. How easy is this to do or is it feasible.

power for LCD TV
I believe all (or almost all) flat panel LCD TVs operate at 12VDC. It's simple to tell by looking at the power cord - if you see a power block in the cord, it's function is to step down and rectify AC at 120V to 12VDC to the TV - just remove it and plug the TV directly into your 12V system. One caution however - the Sharp models are pretty sensitive to voltage spikes so it would be safer to use a good quality 12V surge protector or a 12V UPS if you can find one. These TVs are not repairable if you have a voltage surge. They draw between 1 and 3 amps at 12V so the drain on the batteries is negligible given a typical duty time. Don

Yes the majority of these LCD are 12V
using an A/C adapter to be able to operate on 120V. Our's is a magnavox 15 inch. At 12V it draws about 3 amp/hours which is not a whole lot but you may want to keep track of the usage on top of the other components. Also the cable gauge of your 12V connector should be adequate for the run length. We have an omnidirectional antenna on a pole mounted on the stern rail and it provides great reception. It is great to be under sail while being able to watch the games or keep the little ones entertained in the cabin.

Where can you buy
the 12 volt surge protector or 12 volt UPS. They both sound like a great idea. George s/v French Kiss

voltage spikes
If you need a good 12 volt surge suppressor you are better off making your own. The commercial ones are really inefficient as they convert 12 V dc to AC and suppress the voltage then convert back to 12 V dc. All you need is a hand wound inductor and a capacitor. Supplies for both can be found in any electronics parts catalogue. Look for inductors under chokes or ferrite rings. If you are really interested drop me a line at roosaw@verizon.net and I can walk you through the design process.

Thanks Jerry!
That's what I had in mind. One concern; Dish network. We are an HD customer of theirs. Great service but the bill proves it. I also pay for a hard disk receiver that is rarely used. What I'm getting at is 'Dish coverage'. We are on the fringe. The service would be used even further north in Canada. They are the way to go for me because I'd just use my extra receiver and it wouldn't even cost me the extra $5 a month. That's better than the extra XM receiver on the boat. Free-er is good. Now,,,,,,how much do these things cost? I saw the video. It's NOT a disposable antenna.
