Hey Phil, don't you think that the TV satellite dish creates a lot of potential windage on top of your mast? I would be wary of it on a mast sized for the C 22 through C 27. Really I wouldn't want it on top of any mast. Remember it is a sailboat after all. I do also love electronics to imrove the boating experience, but I gave up on trying to create a house on water a long time ago. A 12 v. TV/DVD will kill a typical group 24 marine battery pretty quickly.
Windage? Nope. Cross-section of the antenna, (just a UHF UFO antenna, not satellite) when on the resting on her lines is less than a spreader. Think about all the other stuff world cruisers hang up high; this antenna is nothing.
Kill a group 24? Maybe. That is why I have a large house bank built from group 27 cells on the C27, to power the AV system with surround sound and subwoofer, as well as the pressurized water, galley sump, LED mood lighting, electric head, running lights and instruments.
I sailed the C22 for three seasons and charged with nothing but a 1.5A solar panel. The TV was used freely with never a depleted battery issue and that boat was equipped with a single group 27.
Be a purist, 'cause I am too. When I am sailing, you know what? I am sailing. I have a tiller boat because I want to feel the wind and water; feel the experience of working with Mother Nature. When I am drinking a beer, by golly, I probably will have two. When I am on the hook though in the fall and want to watch my OSU Cowboys on local network TV I am gonna.
Does it take power? Yea, but so does an anchor light when camping overnight on the hook. So does any other "luxury" use of battery power. Plan for it and execute your plan. If you know you are going to watch TV, just build your system around knowing you will as well as how much. At the dock on shore power? Who cares!
I digress, but back to point. In scope and scale of the dynamic elements, the masthead antenna does not noticeably affect anything in terms of heeling, weather helm, or windage. You are talking about something that would have about the same effect as a Wal Mart sack stuck in your rigging.
Sorry you gave up on "creating a house on the water". I hope it wasn't a dream quashed or unfulfilled. It is a challenge, but it is fun for me. Adding creature comforts to make the boat more enjoyable when I am not sailing is a nice diversion. I still have that goal of installing the ice-powered AC by the way.... I know, I may need to add to the house bank, but i do so knowledgeably in consideration of the probable load.
Don't talk me out of my inspired goals and I promise to continue to share my successes, as well as my "that didn't work so well" moments...
