That is why I mentioned "UnUn." It is taken for granted he will ask, or use
the correct one (Balun/UnUn)...

A balanced "supplies its own ground." A ground or "counterpoise" is NOT
required for the ant to work against...

Warmest regards,

| Yeah, then its a quarter-wave vertical w/ground plane laying on its side

So then a dipole with one leg 5 times as long as the other would be a
"balanced" antenna. I see.

Tell me, how is this "ground" "supplied"? What exactly is a "ground",
say 50 feet up in the air?

Well, "di" = two, so in that sense, "dipole" would not necessarly be
balanced--however, that is not what I expect when someone tells me they have
a "dipole."

Although, quite well granted, it qualifies (my groundplane ant is a
"dipole", but I think I would mislead if I stated that in some circles! (as
it does have a few extra "legs" on one side.) However, it (the radials)
could be viewed as one single conductor, in the sense a tophat might be a
sheet, or a set of multiple wires, or the bottom cone of a "discone"
composed of many "legs" as compared to one solid sheet of conductor...

Semantics: retarded person = mentally disabled = special needs =
handicapped, etc... don't ya just love it!

"Gound" at 1000 ft in the air is a counterpoise (body of an aircraft, most
likely what the neg lead of the power source is hooked to), could be one
long wire to ground too--most likely in need of "tuning" to function
optimally....

If I someone stuck a 1K resistor (or diode-anode towards +) between my
chasis of the radio and the negative lead (probably best to bypass it with a
cap at rf in question), the top of that 1K resistor (or cathode of diode) is
"real ground"--in the sense of "time" being real... they "ground" every
telephone pole now and then, because across distances "earth ground" is not
"equal ground."

If your point is that "ground" is relative--I know a guy who claimed that of
the whole universe....

That guys ground could well be the chasis (even though a 1k resistor!), or
the other side of coil with its center at "ground", or not... etc.

But, those two wires he described are two wires of equal length, so, suggest
themselves as a "conventional dipole", with nothing else to go on--I am
willing to accept that...

I have been wrong before, is so this time--I learn something...

Warmest regards,
John

My intent was to spur some thought about the meaning of the terms you've
so liberally and seemingly authoritatively tossed about. These
"explanations" show that your understanding is, indeed, very muddled and
vague. I suggest you do a bit of study to gain a clearer grasp of these
concepts before you give too much advice about how to apply them.
