[TowerTalk] Rehash of 80 CW/SSB Switchable Dipole/Vee

I would suggest a high quality or bronze banana jack and plug set for each end.  They're self-wiping. Put the plug on the extension wires.

Howdy-

I have been working on rebuilding my 80M dipole setup for camping and the
fall/winter contest season.. My one main question is I know that I can make
the ends for SSB, tune it where i want (most likely 3800).. then on the
other side of the insulator, add the extra length for CW and tune that
portion (~3550).

I *don't* have a pressing need to have this remotely switchable or other
things as discussed in the archives -- a semi fancy matching setup, etc.
Given that the dipole is temporary in nature, it doesn't pain me to walk
outside and clip on the CW section when I want to.

That brings me to a couple questions maybe someone can help:

1) The dipole is being constructed with materials to handle 1500W (balun,
wires, etc.) -- Will this extra length of wire for CW arc where I "clip" it
on to add the extra length at the end of the SSB wire running 1500W?

2) Given that it's "temporary", how would one suggest constructing the
point where I switch from SSB to CW.. Alligator clips? There may be a
potential for exposure to the elements (mostly rain and some snow).

Thanks,
WT2P
