Dick, PA0SE, and others have recently been using a multiplication
factor of 1.83dB to obtain ERP. This is the supposed gain of a
vertical antenna over a dipole because of ground reflection.
One more thing to mention : when you MEASURE your by the way Dick suggests
you don't have to take in account any multiplication factor if you have a
short vertical antenna. When you measure at 2 .. 3 km and on the ground you
are in the plane of maximum radiation of the antenna. What you measure will
be your power in EIRP. Only for antennas that have maximum radiation at a
certain elevation angle a correction factor will be needed.
