Jon, Top Quality Gin Pole kits can be obtained from www.w9iix.com for about
1/3 the $700 amount you quoted. I'd also be reluctant to recommend a roof
mount tower as most people don't install these with proper mounting know how
and reinforcement and also, more substantial, and the biggest reason, the
structure is suspect to severe damage from a potential lightning strike.
I've seen one house and one garage, both suffer severe fire damage from
lightning hits to roof tower systems over the years. A serious consideration
that should be mentioned when rooftop towers are suggested. Everything is a
trade-off of some kind. Rooftop towers may be less expensive than a ground
mounted tower, but there is no comparison where safety is concerned. I, for
one, do not care to jeopardize health and well being of myself, my family
and my home for some dollars and (questionably) somewhat less efforts. For
safety, grounding techniques aside, antennas and towers have no place being
attached to dwellings in any area where lightning is a possible
consideration.
