Hi Howard, the Pvc pipes are mounted on existing vent pipes on
the roof of each building. The antenna has a kind of print l
shape to it because I ran out of room to go straight so it
required 3 pieces of PVC as well as the center feedpoint on the
vertical pole which comes up from ground level between the two
buildings. Might as well have no antenna right now because I
can't even hear any of the WWV signals, just a whole lot of
noise! Jim

Hi Jim,
Just curious, how did you mount the 5 foot lengths of PVC to the
building
and where did you mount them?

The Alpha 1 and Mp-1 are supposed to work on 80 to 6 meters.
The
philosophy or approach for each is different. The interesting
thing about the Alpha is that the matchbox is supposed to do all
the work other then your tuner, so you don't have to go out and
physically change the antenna length when you change bands. But
I think you lose some efficiency as a result of that. So
there's
no getting around the fact that small antennas are just going to
be compromises no matter how you cut it. I am really lucky
here.
Also living in an apartment, I asked the landlord if I could put
up a Shortwave antenna and he said sure, long as it doesn't mess
up the visual quality of the building. I have a Windom that
uses
a couple of 5 foot PVC pipes to support the wire about 4 to 5
feet above the roof. The feed point is on a pole with a
vertical
for 2 and 70 centimeters that is attached to a clothes line pole
down between two apartment buildings if that makes any sense.
