The FCC rules are very clear. 200 watts PEP output from the transmitter.

Doesn't matter if you have a -20db gain antenna (wet noodle) or a 10Dbd Yagi.

200 watts output. Period.

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.

From some of the signals I hear on 30,
they must have some very big antennas !!

This is an interesting question.
On the ARRL Page it states,

      30 Meters

Maximum power, 200 watts PEP. Amateurs must avoid interference to the fixed
service outside the US.

Now is that Input Power? Output Power, or ERP Power?
