If that charge cycle theory floating around were true, an average car
battery wouldn't make it three years in a commuter vehicle.
Not sure I buy into that as my plain old (cheap) #24 car batteries I use
with a solar charger typically give me over 10 years of service.

Yes, but speaker wire is only good for audio up to about 25 kHz. It has a
frequency limiting component in the wire alloy that must be removed in order
to use this type wire at RF.
This removal procedure is fairly easy to accomplish. First, soak the wire
in a bucket of laundry detergent and
I thought I said that...
Oh wait I DID say that !
AND, A VEE will have a slightly more omni-directional pattern.
(That's where the gain of the horizontal dipole went !)

I wonder if anyone has ever tried, for want of a better name, a "Skeleton
Cone" which consists of a single horizontal wire connected to the coax
center conductor and two sloping wires at 45 degrees, in the same plane
connected to the coax shield. A true Discone antenna would have many

How are you determining resonance?
If you are measuring strictly voltage standing wave ratio with for example, a
Bird 43 meter, then a reactive system whose characteristic impedance is far
from 50 Ω, may in fact show the lowest SWR meter reading at a point well off
the actual antenna
Yep, ur right Don. A freebie Harbor Freight digital voltmeter appears to
have a helluva lot better accuracy than reality.
Digital calculators on the other hand, ARE accurate.
This changes our mind-set, simply because we see all those digits past the
decimal point on a dVOM.
it was better when
To quote that ancient Chinese philosopher: Sum-Ting-Wong"
Find that and your "howls" will go away.
There's far too many satisfied users of the CM-500's for anything that
drastic to be the norm.
