[TowerTalk] Which tower base?

[Dan Levin]

I am planning, at some point later next year, to install a tower at my new
vacation QTH.  This winter, there is going to be a construction crew on site
with a backhoe and a concrete pumper.  So it seems like it would be a good
idea to put in a tower base while they are there...

I think that I will probably put in Rohn 55G, with 45G a backup possibility.
I realize that most folks bury a short section in the concrete, but if I do
that I will be bound to one type of tower, right?  I'd rather not decide
yet.  Is there a base that I can put in that will support either tower type?
I'm not worried about the amount of concrete, rebar, etc.  I can overkill
that easily enough.  I am more worried about the metal part of the base -
does Rohn make something that mounts on a set of J bolts the way most
crank-ups do, or some other base mounting system that would allow me to put
in a bolt or two or three and decide on my tower type later?

Also, since I don't plan to put in more than 150' of tower, I am thinking
about pouring guy anchors 120' feet away from the base.  If I later decide
to put in a shorter tower (say 90'), is having the guy anchors at 120' going
to be a problem (other than the extra cost of the EHS, which I can deal
with)?

Thanks much as usual,
