You're welcome. The idea is not original on my part. There seems to be
three schools of thought on how the shields are handled on the outside. Lew
McCoy suggests bonding and grounding them. The Wireman in his booklet
suggests keeping them separate and not bonding nor grounding them. And the
third method that I use. I did not employee Lew's suggestion as I thought
there might be the possibility of ground loop problems on some frequencies
and I felt that bonding on each end provided a better overall shielding for
running the line near conductive surfaces. Probably all three systems will
work okay - its a matter of personal choice.
One thing I also did was to use banana plugs on the outside for connecting
the ladder line to the coax. This allows me to easily disconnect the
antenna when electrical storms are near. Although high winds will do the
disconnecting for me <g>.
Hope this helps
