Hello Rik,
Thursday, November 19, 2015
Whilst you experts argue the technical niceties of the challenge, let
me ask what might be a simple question to you guys. What is the
minimum number of two contact vac relays I would need to go from
strapped ladder line to top of loading coil, to unstrapped ladder
line, disconnected from the top of the coil, and now connected to my
coaxial feed line, presumably itself disconnected from ground and the
bottom of the loading coil? It seems a lot would be needed to me....
:( Thanks! I can see me leaving wet weather gear by the front door and
doing this manually!
