Any passive RS232 port splitter must divide the active TX source to two RX
inputs, but can't negotiate multiple sources. Thus, if only a single TX
source is needed and allowed, it should work. It's sorta like an RS232 hub
as apposed to a switch.

Ron, this work hardens the wire and removes the normal annealing. This can
be done with most soft metals: copper, silver, brass, but not aluminum
which must heat tempered like 6061-T6.

Jeff, you're correct about old used linear amps. It might just be
better to get a used Ameritron amp with the cheaper 3-500s
or 811s in the finals. They will have all of the modern features
that one needs these days. I've been very happy with my AL-80B
for five years now, but cheaper used

The J pole I got gave the closest feed impedance to 50 Ohms (@ 146 MHz)
when the four radials were exactly perpendicular to the radiator. When

No, any reasonably conductive metal will have a free space
velocity factor of 1.0. However, putting conductive objects
very near to a metal wire or tube or rod will change this.
Also, any insulation on a wire will reduce the velocity factor.
