Stacking two 100 ohm impedance quads is electrically about as easy as
it gets. An electrical 1/4wl of any good quality coax from each
antenna to a
T.
50 ohm cable to the shack.

Thanks. I would've thought it needed to be 1/4w/l of 75-ohm cable,
but
I'll try it.


You are right to question to advice Sal.

Of course with a 1/4wl with VSWR=2, the Zo does matter.

However, Jimmie might have meant each leg to be a 1/2wl (electrical)...
close wasn't it! In that case, Zo isn't critical.

Owen you are a good mind reader, sorry about the typo, should have been
1/2 wl.

Not to mention you would never get enough space between the antennas using
1/4wl sections.
