You loose something and you gain something else. The longer loop (320m) will
give you a lower elevation angle at the low frequencies (160, 80 m...)

I did not see this in L.B.'s article ( in a quick read through) and it would
seem to go against the basic premise that takeoff angle is solely a function of
height above ground. I did a loop model in AO and did not see any changes in
takeoff angle as I changed loop circumference. Can you point me to the section.

Tnx,
