Howdy --
There are 2 ways to do it: 1) tape all the cables coming down the mast
together and leave 4-5 feet or so between where it leaves the mast (or
antenna or whatever) and where it attaches to the leg, or in a crank-up case,
to the coax standoff.
2) is where you coil 2-3 turns of coax around the bottom of the mast
before attaching it to the leg/standoff. You need a flat plate on the top
and enough room for the coax loops.
> 2. What are the best choices for the part of the coax next to the
rotator?
Should all the moving coax be some kind of "ultra flexible cable."
As long as you use a coax with stranded center conductor, most
coaxes will work.
> 3. How do you keep the coax from getting "messed up? when raising and
lowering the crank up? I have heard there is a way to keep the coax inside
the tower tangle free. Is that so?
NO. Sooner or later the cables will get chopped and I'm having
trouble picturing how you'd actually do it.
Again there are 2 ways to do it. 1) Secure the cables to the
standoffs. This is time consuming since you have to run the tower up and down
repeatedly in order to get everything spaced right. 2) My preference is to
tape
all of the downward cables together at about one foot spacing and while
it's secured to the top cable standoff. In this case the cables will rise and
fall together and pass thru the standoffs. When lowering it, the cables
will just lay on the ground as it comes down.

Woo woo - fun ahoy!
