A 30 meter beam size would be between a 40 meter and 20 meter size and a lot of
hams build both. A 3 element beam for 30 meters would probably give at least a
6 db gain, which is equivalent to increasing your transmitter power by 4 times.
A 100 watt transmitter power into a 6 db gain antenna would be equivalent to
running 400 watts into a vertical or dipole which usually have little gain.
