Anybody ever mount a rotor in the attic and run the mast straight up
thru the roof? Seems like I remember an article in 73 Amateur Radio or
QST about this. I'm considering trying this, theirs a nice pop-out in
my roof for a vent that would be perfect for this. Then the hole would
not be in the main roof, just the small section of the pop-out. Seems
like it would be fairly easy to seal, and could also put a large pan
with a drain line under the rotor just in case any water did get thru.
Any idea's, suggestions? Thanks

I remember reading that article and it seems a ton of work/prevention
goes
into that method. I'm going the Roof Tower direction and Glen Martin
makes
some pretty nice ones, 4, 8 or 9 feet would seem to work better than
what
you need to put a mast through the roof.

Just a 2nd idea

I'm going 9ft myself. Its all built but setting in my garage waiting for
the
water we are getting in the Puget Sound to stop. Which at this rate
might
be spring .

**Thanks for your feedback! One of the reasons I am thinking about
thru the roof is for a little stealth, I would only want to put the
antenna's, ( 2 meter and 6 meters beams) about 5 ft above the roof.
They would be mostly hidden when looking at the front of the house from
the street. They are fairly small antenna's, I have them mounted on a
small telescoping mast right now with no problems for the last two
years. Rafters and joists are 2x6 and 2x8's, so I'm sure those are
heavy enough. I would think that between a cone shaped metal flashing
on the mast with rubber or some sort of UV resistant tape to seal it,
and then a rubber vent pipe seal at the roof level and maybe even some
o-rings on the mast inside the roof, plus a pan underneath the rotor
should insure no moisture inside. Of course all this would be grounded
very well! But a roof mount tower would sure be alot easier!

I have a small rotator and a short mast fastened to a vent pipe in the back
of the house for a UHF TV antenna. Something like that might work, if the
antennas are not too big. I suspect the overall long term cost will be less.
