Antenna Quality

Also, get the highest quality antenna you can find...............

Digital brand is about the king of the roost.

Shakespeare galaxy series also very good.

Both readily available in the Houston area.

The world's best radio is only as good as the antenna it is hooked to!

Antenna gain as told to me......

As endtuition says, higher Db gain will improve commo. The practical fact of the matter is that anything higher than 6Db on a small boat is nearly useless as the main communications antenna.

The transmitted signal around a vertical whip antenna is in the form of a torus or doughnut shape. The higher the gain, the flatter or thinner the torus until it would more resemble a CD than a doughnut.

A 9Db antenna on a second radio would be acceptable. You would, theoretically be able to transmit and receive farther, but you give up reliability due to the motion of the boat. Pitch and roll aim the signal at the water or the sky.

Very high gain antennas are best used on a stationary location, as a tower on land or an oil rig.
