Welcome back to the group, Barry. I, and I know many others, really
appreciate hearing the straight story from someone who truly knows what
he's talking about. Thanks!

Polyethylene and polypropylene ropes are rapidly destroyed in sunlight.

Speaking of someone who truly knows what he is talking
about Roy, here's a technical question for you.

Given that a mobile antenna stinger has a VF of
approximately 1.0 so we can determine the approximate
number of degrees that it occupies and ...

Given that we can use EZNEC to determine the feedpoint
impedance of that stinger, it seems to follow that ...

We should be able to use a Smith Chart to determine
the characteristic impedance (Z0) of that stinger.

Yes, no?
