Yep, we do the radios at the bottom on these. Part of what prompted
the post is that the trees grew this spring and we need to the the
antenna higher. And then we have those few that we need to get 360*
coverage from, so we need to get above the dome.

One way to handle that (I often do this because I'm very afraid of
heights) is to mount the antennas at the top then run good cable down
to a nice play for the radios.
LMR 600 only looses 3 or 4 dB per hundred feet. For runs of less than
50ish feet I'll usually just use LMR 400. If 3 dB of cable loss kills
your system you'll be fighting it every time something changes (heavy
rain, fog etc.) anyway. Yeah I know weather isn't supposed to affect
these bands but someone forgot to tell the radios that :-).

Most silos like scott is dealing with have no ladder going to
the very top. Imagine a domed water tower with no ladder to the
top of the dome. They never were designed to have to climb to the
top. No reason to. So what you are left with is a ladder that
goes to where the dome starts. You then have another 10 feet or
more to be able to get over the top of the dome. In otherwords,
you can't mount at the top of the dome. You have to come up with
a solution to get you over the dome.
Sure, you could bring in a lift or crane and mount stuff.
However, maintenance and repair become the issue. You have to
bring that lift in each time because you can't climb to the top of
the dome.
