Hmmm... if I hadn't already obtained a workable HF rig, I'd ask if you
wanted to give it a good home.   :-}

Tuned.  (My pingers got tankled.)   :-/

I'm sure it would.  After all, it's literally a shield.  But how much
difference would it make, both in gain and F/B ration whether the screen
is flat or bent into a corner-shape? (Assuming the same number of square
inches of screen.)

More likely I'd make one for 420, though I'll probably build a coaxial
for that.  I'm not that intersted in super DX, (unless I do it through
a sattelite - including the repeater on Mir).
