I want to raise the center of my 91 ft folded dipole to at least 35
feet. I live on the west coast of Florida with all the attendant
possibilites of hurricanes. I cannot afford a retractable tower and do
not have room for proper guy wires. I want to be able to put a pulley
at the top so I am able to lower the antenna in the event of high
winds. I have a cement block house with a roof peak of about 16 feet,
I would prefer not to have to pour a base for the "mast".
I would appreciate any advice on supporting the "mast" to the house
wall and what material to use for the "mast" so that it might not be
permanantly bent by 125 mph winds.

Any constructive help gratefully welcomed

If you can find a competent machinist in your area then purchase two
decent size pipes and have the machinist install a base seal so you can
force mains pressure into the base , the centre pipe will lift and then
can be locked at full height or dropped in moments.. hope you follow
what I mean .Ten metres is very achievable for little outlay , a simple
short guy and bracket to the house will strong if installed correctly ,
talk to a carpenter for good advice .Good luck.
