[Towertalk] Advice on Re-doing My Antennas

[Eric Rosenberg]

I've finally collected everything I need to re-do my small lot
(micro-pistol) roof set-up. 

I'm replacing my 6 ft. quadpod roof tower with a somewhat unconventional
10 footer (an older, refurbished TET model that has a 4 foot
base as a quadpod and a 6 foot, 4 sided, 6" face top section
that will need to be guyed).

My plan is to put the C3-SS up 4 or so feet over the thrust bearing.
 I have a F12 rotatable dipole (actually, a C3->C4 expansion
kit), and want to put that above the C3-SS. 

The questions are:
-what's the recommended material for guying?
-how high do I put the rotatable dipole over the 
  tribander?  
-does the rotatable dipole go perpendicular or parallel to 
  the tribander elements? 
-does the rotatable dipole need a balun? 

Thanks in advance,
