I am building a small, Square Rig (Hermaphrodite Brigantine), two masted, Sailing Ship: and am putting a HF transceiever aboard (Icom HF-730).

I am in the final throes of antenna selection. The masts are fiberglass, twelve feet long, and the hull (a San Francisco Bay Pelican), is wood and also 12' long.

For convenience I am looking at an inverted L up one mast and accross to the other and a smart auto tuner.

I am also looking at a good quality Screwdriver antenna 80-10 meters.

My question is will one "get out" significantly better than the other?

A second question is there something significantly
better?

The ground plane will be interconnected wire mesh mats covering the inner surface of the hull. Approximately 11'L x 5'W = 55 square feet.

The physically larger inverted-L should perform much better than the screwdriver, especially on the lower frequencies.

If you use an auto-coupler to match the antenna, remember to ground the other side of the coupler to the keel plate.
