Well, ya', an adjustable whip(s) is good, especially with the cost of
copper and the pain in "resoldering your prunings." LOL


Incidentally, one of the tricks I learned (the hard way) was to
replace the mobile whip antenna with a piece of copper electrical
wire. Then cut it to length, tune, optimize, test and whatever. Once
the optimum length is established, replace the copper wire antenna
with the real stainless whip, cut to the exact same length.

You have wine? Why didn't you say so, that changes everything:


The antenna transfer function of wine is highly exponential and very
non-linear. A little wine will produce a superior antenna. However,
incremental increases in wine dosage will tend to have lesser effects.
At some threshold, additional can cause a substantial drop in
performance. It may even go negative. Think equilibrium.

Or, to summarize, the more complex the antenna, the more meters you are
going to need ... LOL


Kinda reminds me of a former tech. All day, he would spend his time
working with the latest state of the art test equipment in the lab.
After hours, he would drag out his ham radio, and tune the xmitter to
maximum using a light bulb dummy load. Attempts to convince him that
the company test equipment might be useful for dealing with his radios
were futile.

If away from my laptop, the programmable calculator is always in my
pocket! (I mean, my gawd man, I have space invaders on it!) straight-face


That doesn't leave much room for the pocket protector. I collect HP
calculators. There are numerous calculators scattered around the
office and house. No need to drag a calculator around.

... some patents are NOT what they used to be ... but then, there has
always been some suspicion about the politics involved, not to mention
courts ...


There's plenty wrong with patents that I don't wanna get into. Suffice
to say that it's very helpful to understand something about patents
before trying to create one. I'm just suggesting that you make the
effort to read patents.

Groan. I decide to stay home today to recover from my home cooking.
Outside, PG&E (the power company) and the local tree service just
arrived. There goes my power...
