Dont forget that a good location will increase the total gain up to 11 dB or so and if the TA program is used the height will be selected to put the power where wanted.

An old CC 40-2CD is an easy conversion to 30. Im over 250 DXCC on 30 with 100 and 150W rigs and pushing 150 with 5W without trying very hard.

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?
