Howard, yes, I must say, I have been very surprised how well the 
antenna works when conditions are good.  I have even worked 
people on 60 meters where the antenna has a terrible match by 
just turning my power down to around 30 watts.  But I worked a 
guy on the RV net on 40 meters just yesterday who was very weak 
and I truly thought he wouldn't hear me.  He came back after my 
first call.  I guess his noise level was much less than mine.  
here.  Well, am now in a conversation with a couple of local guys 
on 40 meters.  Take care, Jim WA6EKS

Jim,

When the bands are "normal" does your antenna work pretty well?

I bet the antenna wire isn't noticed unless someone points it 
out.

I bet more apartment dwellers could do something similar, but the 
mention of
an antenna congers up big unsightly monstrosities, so we don't 
even get a
chance to show that the wire from the building to a tree or from 
building to
building wouldn't be noticed.

Many antennas are not as ugly as power lines, huge signs or even 
light poles
in the parking lot.

 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.
