The 1500W will be 100W or less when compared to those using gain antennas,
especially on 40M and up where a yagi has substantial apparent gain from
elevation pattern compression and ground gain.
An effective receiving antenna for 160-40 is simple, even for a small
property. Buy the 4th Edition of Low Band DXing.
