Well, I can't tell from your description what the heck kind of tower it
is. How long are the sections? What's the distance across the face? What's
the width of the legs (I'm assuming they're round legs)?

Congratulations and welcome to ham radio! There are thousands of CB'ers
who have gotten ham licenses and they're having more fun than they did

Hmm, the MFJ 1798 is a "no radial" vertical. I doubt that the
manufacturer wants it mounted that far off the ground. What does your manual
say about mounting distance?

I'll guarantee you that this is A LOT OF WORK. I did it a couple of times
and swore "never again". I spent as much for the spray cold galvanizing paint
as I did for the tower. To say nothing of the TIME involved. Since you've got
a lot of time available - GO NUTS!

Don't have a clue. Please describe the tower in more detail.
You can get some good inferences from the Rohn catalog if you use a
"similar" tower as a reference.

Without knowing what kind of tower it is it's impossible to say if guy
wires need to be used. If this is a guyed tower, no - a 4x4 is not adequate.
Do you know what your county windspeed is? You can find out from <A
HREF="www.championradio.com">www.championradio.com</A> under Tech Notes. You
need to use that as your design windspeed. What county and state are you in?
It's obvious that you're not going to get a building permit. Since you're
not going to have an engineer bless your installation, I'd go kind of slow
until I had all the necessary information so you'll wind up with a reliable,

ANY ANTENNA is sufficient to get started. Virtually everyone started out
with some sort of funky wire or vertical antenna so go ahead and get started.
It won't be too long before you realize how well - or not - it's all working.
> 4. can the Belden 8281 (TV) be used for any of the ham ant's
Probably but I suspect it's 72 ohm coax whereas most all ham radios and
antennas are designed around 50 ohm specs. You'll have a little more swr but
it's not fatal. My question is "What are you going to do for connectors?"
(I'm not familiar with this type of coax.)

Some people use their guy wires for antennas. Just put up the wires and
see what happens. Some designs will work better than others. Jump in and see
what you get.
