[SADXA] 440 Antenna

[WD7F - John]

Does anybody have a high gain 440 yagi antenna we can beg, borrow or buy so
we can determine the required antenna to link to Mt. Lemmon?

We have a co-phased, 2 array (side by side with about 1/2 wavelength
between), each with 6 or 7 elements and a folded dipole driven element,
vertical polarized ATV antenna(s) that we have used for several years but we
have no idea what the gain of the this thing is.  The only reason we think
it might to ATV is that someone wrote "ATV" with a marker on it.  We can't
seem to fully quiet the popcorned 448.35 from K7IOU's QTH and, of course,
there's a multi-path issue and lots of rock.  

And, oh yeah, any antenna you might wish to donate to the cause would be
appreciated.

Thanks
