[VHFcontesting] feeding a crank-up, tilt-over self-supporter

[Ed Kucharski]

After reading The World Above 50MHz lead article in July QST I see that 
crank-up, tilt-over self supporting towers are being used by some vhf+ 
ops.  I hate to climb and have been thinking about a crank-up/tilt-over 
self supporter (US Tower HDX555, Tashjian LM-354HD).  What are some common 
practices for using low loss coax (1/2" superflex I have lots of 
this,  lmr400uf?) from the top of the bottom tower section to the antennas 
at the top of the tower (in my case a vhf-uhf-microwave array)?  For 
tilt-over purposes, at the bottom of the tower, I'd like to use my existing 
7/8 and 1&5/8 in. heliax from the shack via a trench up to the top of the 
bottom section (22ft).  I'm concerned about the movement and potential 
damage of the hardline during the tilt-over and tilt-up process.  Thoughts 
and advise?
