>There was no contest at all: even at 50ft, the 40-2CD is
1-2 S-units louder than the 4-square.
This should be no surprise. Even a dipole up 1/2 wavelength
will beat a 4-square. I recall a dipole's gain is in the order of 2-3
dB over a vertical for equivalent grounds. Add another 4-5 dBd for a
2 element Yagi and you are around 6-8 dB over a 4-square. The only
place a 4-square can realistically compete with a Yagi is if you are
over salt water.
