Steve--Those are GREAT photos! I frankly think that ham radio is a lot of fun, but being able to put up an antenna and put one over on the HOA makes it even more fun! I like your arrangement. However, have you tried getting the antenna up a little higher on your roof? You could still keep the horizontal portion below your ridgeline, but perhaps mount the plexiglass "tower" on one of those pipes or some other attachment point on your roof. In any event--good job outsmarting the HOA!
This also shows that there are always work-arounds to restrictive covenants. Some hams just quit in the face of such covenants...others, like you, overcome and adapt.
I considered putting it higher, but decided against it for a couple of reasons. One, those end supports were cut from the largest. thickest piece of plexiglas I could find at Home Depot. Two, I need as much plausible denial as possible -- if someone on the HOA challenged the wire as an "antenna", I could get away with saying "it isn't high enough to be an effective antenna". Which is true. It works OK as an antenna (better than something hidden in the attic), but it doesn't have the performance of something higher in the air.
The whole antenna was designed to be a mirage with multiple layers of "cover". When I stand a few feet away at the back wall of the house, the antenna is impossible to see. If the HOA were to complain about it, my first question would be "who trespassed in my back yard, because that device can't be seen past my wall". If they press the issue, it's a "security device". If they ask how it works, it's "proprietary information".
You'll also notice that the end supports are not located all the way at the ends of the eaves. This prevents the antenna from being seen from the front and most of the side of the house.
The antenna wire itself is 18-gauge "polystealth". It paints nicely. Just use a foam brush and the wiring can melt in to a house or roof.
All that being said, I'm tired of playing games and it would be great if the FCC would stick a fork in the CC&Rs nationwide. The Amateur Radio service is being decimated by HOAs.
