Chris,
Ah, you have touched on the difference between science and necromancy.
Cheers for now, 73,

TIME (the old tattle tale) WILL TELL.
There was a time when 1/4 wave verticals where the only antenna and hams
were given the HF bands as they would never get out of their own
backyard. I can remember 2m as a real problem and tubing used for anything
greater than 2m. A Rx for 2m filled half of the back part of a 1961 VW the
Tx the other half. The poor bug could not idle too long or the battery
would die. Now we have 2 band HdHlds that work far superior.
So, I would not throw it out but work with it, who knows?
Has anyone done anything with the fractual antenna?
