Your car wears it's tire mittens, yet sputters at porch lights due to
excessive
carbon buildup on the various intake valves.
The carbon expands as it heats up, and then the valves refuse to seal,
which
leads to a loss of compression, which leads to a poor operating ability as
it
passes go to collect it's $200 while operating 3A at field day.
I asked my cat what is likely the cause for this peculiar phenomenon, and
it
laughed at me and pointed to the northeast.


Sorry, looks like random garbage to me.

The irony is *very* strong with this one.

You got it Toyota. It looks just like the random garbage that
comes from your keyboard. I just wanted to show how your gibberish
looks to anyone that has even half a clue about short radiators.
Just the title of this thread alone is a false statement.

The fact that short antennae are poor radiators is borne out by advanced
EM texts.

Might I remind you that in your case the fool is better advised to keep his
mouth shut
rather then open it and confirm to all?

Prove it. Show the tests and the results. Being as such bafflegab
fodder does not exist, I shall not hold my breath waiting for such
information.

Even my cat knows there is no such thing as the tooth fairy.

Well, prove I'm a fool, you braying jackass. The ball is in your court.

Show the tests, and the results which show a small antenna is an
inefficient radiator. Until you do, you have no room to remind me
of a damn thing.

Thinking people all around the world have known for many years that
even a small radiator will radiate nearly all power that is applied
to it. So where does that leave you? In an isolated rubber room?

Over here in Brit, there is a glaring illustration of the abject failure of
the new
examination scheme, in the person of Stephen Thomas Cole. M0TEY, who
had chosen his callsign as a memento of his days as a CBer. Cole is
completely
untechnical and all his posts (including those to this NG) are abusive and
attention-seeking.

You are indistinguishable from Cole.
