[TowerTalk] Questions from the unwashed on a small project.

[Stan Labinsky Jr.]

Gentlemen, ladies, I'm in the process of repairing my standalone garage 
(replacing some of the Dutch Lap siding and of course, painting) to use as 
the upper support (by wall bracketing) for about 40 ft of 25G.

Rohn says that 40 ft of it can stand unguyed, but probably with not too much 
of an antenna.

My plans are for a TA-33 and maybe a smaller six meter beam above it.  Would 
stand thirty feet above the roofline.

The upper bracket would attach to the tower just below the first to second 
section joint.  I've drawn up a bracket made out of Unistrut, which to me, 
looks to be more substantial than the factory offering for far less cost. 
If curious, I can attach a jpg of it to a follow-on note, just don't know if 
the reflector will pass it.

Question(s):

I have the choice of using a base plate (all this courtesy of an SK estate 
sale) listed in the catalog as the BCP25G, but planning rest it on the 
ground with an 8 foot ground rod set as the pier pin.  I know that 
galvanized on earth is not a good plan and would probably coat it with some 
sort of undercoating as a protectant.

Or, I can build another wall bracket and attach the lower end of the tower 
to the wall as well, set at about a 1/2 foot above ground level, the tower 
legs setting on some concrete pavers.

My concern would be, using only option two, that the two point leverage 
against the wall might be excessive where using just the pier pin and upper 
support would put less twisting stress on the wall.

Or, I could use both at the tower bottom, but see that as over-kill... 
either-or.  Also, suggestions on an on-earth undercoat for the base?

Thoughts anyone?

Stan
