I have a 3 sloper array off the tower to the SE, SW, NW. They are half wave
? loaded sloping dipoles that are about 80 ft long with loading coils to get
½ wave performance on 80. I just switch in and out about 2.5 ft of wire to
make them resonate on 3550 vs 3775. Its slightly OCF on CW but works like a
champ. Very simple. About 150 khz bandwidth (2:1).
I also have a 2 el W8JK style wire beam on 80 to the NE. There I have feed
extenders for 80CW vs SSB that I manually swap out. I also use a remote
tuner at the connect point of the open wire lines feeding the array because
the antenna is very narrow banded (75khz 2:1). That also works wonderfully.
