As most readers know, I've been preaching that everyone
needs BOTH High and Low antennas to cover ALL the angles
supported by the ionosphere. IMHO, everyone would benefit
by having a good tribander (or separate monobanders) at
40 ft in addition to higher antennas. A 40 ft high horizontally
polarized antenna will cover up to 20 degrees on 10M, 30 degrees
on 15M, and 40+ degrees on 20M which fills in the NULLS
of higher antennas for the high angle openings and close in
stations. During the SS, my 40 ft high TH7 was 10 to 20 dB
louder into W1,2,3 (500 to 800 miles) than my 4L15 at 55 ft
and my 3L20 at 75 ft.
