[TowerTalk] Covert Mast and Yagi

[froggy at awaforums.com]

Here's a challenging question (at least challenging for me). I 
currently live in a covenant restricted community that doesn't allow 
antennas. Since I have trees around the house, I realize that it is 
not difficult to set up a dipole, or two, or three. What I'm curious 
about is whether one could setup a mast of some sort that could be 
extended at night with a yagi (or similar) antenna at its top. I have 
a dogpen (no dog) at the side of the house that has sides six feet 
high (chain link with plastic strips to hide the inside from view) 
with  internal dimensions of 12'X12'. I have had musings about 
possibly "landing" the antenna in the dogpen before the sun comes up. 
Otherwise, the whole project gets turned into a "pumpkin".

Force 12 has some interesting extendable masts on their website. Are 
there other masts that extend to a workable level, and still collapse 
to the six foot level I need to hide the antenna during the day? Am I 
smokin' crack on this one, or are there directional antennas that 
could could fit into my dogpen dimensions when retracted.

If nothing else, it's a thought exercise. I just don't have the 
background to figure out if it's even possible with off the shelf 
hardware.

Regards!
