I would use Buryflex (see http://www.davisrf.com/coax.php and
http://www.eham.net/reviews/detail/4515 ) for it all. in my experience it
holds up to UV exposure better than LMR400 and resists moisture ingress too.
I have several 240 foot runs underground since 1997, and so far no problems
or detectable change in loss on ten meters. For the rotor loop, I would wrap
the coax around the tower twice to simulate the greatest rotation you will
encounter plus some safety factor.

Hi Group,
I will be ready to install my new tower in about 3 weeks once the concrete
has a
chance to get accustomed to its new home. My question is which of these two
choices of coax is going to be the best and easiest to work with? I will
have a
100' run and it will be used with a Mosley TA-33 so the area I am concerned
about is the rotor loop and any turns of coax I might want to place on the
boom
of the antenna. I currently do not have either coax in hand and therefore I
have to ask the experts.
Tnx and 73
