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...), but
the beam pattern on 20m - 10 meter will suffer. Look at W4RNL's analysis
http://www.cebik.com/atl1.html. Even a 160m loop is inferior to an 80m loop
on 10 meters. Remember to scale his figures, as the 320m loop will have this
problem already on 20 meters.

(An 80m loop is my main antenna)

I am going to put up a horizontal loop @ about 60' in hopes of having a
decent 160-10 antenna. Is there any adavntage to increasing the the total
length from 1 wavelength at the lowest freq. (about 530') to 2
wavelengths(1,060'). i
