[bars] Radials longer than a roof

Hi Andy,
This is *EXACTLY* the kind of feedback I was looking for, an alternative
way of doing what I was planning. And frankly, what you are suggesting
makes perfect sense -- instead of just running the radial through the
insulator at the end of the roof and draping the excess down, installing
the insulator on the side of the house and running the radial to the
insulator. The document you attached is *excellent* and I am going to read
it carefully before proceeding.
In fact, your suggestion has me thinking that perhaps I should install
poles *away* from the structure of the house so I can put the insulators at
the top and stretch the radial to maintain its vertical positioning. I
would only have to do the two 33ft 40 meter band radials that way as the
other radials fit on the roof, and I already have the poles, those green
army surplus tent poles Greg is selling.

*Thank you*. This is *very* helpful. :)
73,
