[TowerTalk] Return on investment (golden rules) for antenna installations

[Joe Subich, W4TV]

The model used for the yagi is far from optimum and contains losses
not likely to be present in a well designed antenna.  The losses in
a half size element are typically less than 0.5 to 1 dB unless the
loading/matching circuits have extremely low Q.

That said, Moseley antennas have been found to be quite inefficient in
actual range tests (see the W0AX/K7LXC tribander books) to the point
of showing loss compared to a dipole on some bands.
