I don't know if gain is the right word. Is 'least loss' more appropriate?


Gain would be appropriate when comparing one antenna to another, or to an
isotropic source.

There may be something that resembles an isotropic source, but these guys claim
an appropriate antenna is just hypothetical.

The idea of 'gain' is still troubling, though. I can see a tuned circuit
building up energy if there were no resistance in the circuit. With the
minuscule voltages available in many shortwave radio signals, there isn't much
to spare. Getting the antenna to lose as little as possible is an easier concept.

For you perhaps... You simply need to get a good antenna book.
