Renzo, I'm sure members can answer your other questions I can't, but may I
ask why you would choose 1/4 wavelength "slopers" when a 1/2 wavelength
dipole (or several, as you planned) on the same tower would take up no more
space, and probably significantly improve reception?

I would like to install 4 quarter wavelength slopers with different
directions on the same tower. Any questions:
a) Is it a fine idea to select one of the slopers through a relay box
located at the tower?
b) Is there a way to use the selected one like the driven element and the
unused elements (3) like reflectors?
The fact is, is it possible to realize a parasitic electrically rotated
array using the quarter slopers instead of the
half wavelength (ARRL Antenna Handbook)?
Many thanks in advance for any possible infos about!
