Those 2 coils on the x-terminator are only 5 turns and 9 turns which does
nothing on 27 mhz. Even a keyclown like me knows this.

You are probably right on both counts......The coils and the keyclown
part.


So you think the coils do nothing? Me too.

If you are not a keyclown why are you so interested in a 15,000 watt antenna?

Just a curiosity.

Originally I never bought in to the belief that such a short antenna
could out do what I thought was the best antenna. I always assumed
that the full size 102"SS whip was as good as it gets.

After hearing this nonsense about these short antennas I inquired
about what this antenna was and where I could get it. I was determined
to un validate any claims that a shorter antenna could out do the 102"
SS. I was told one of these antennas was the X-Terminator. I ordered
one for testing.

After setting up a valid way of testing it I was surprised at the
results and posted them. It's to bad some can't stand the thought
that a shorter antenna can out do a longer one. It must disrupt
and totally disorganize their supposedly organized way of thinking.

How long is that antenna? (X-Terminator)

I think it is 5' 4''

Actually it's 62"..........If you can wait a second I'll give you the
entire dimensions. Maybe Mmana wants to know?

Thats what I was thinking, maybe the dimensions of the 3 sections
and coils? Give me something to do tomorrow, being Friday.

Tnom;

I plugged in the values that you posted. By simulation, the
Stainless whip has just about a 1 dB edge. The S/S whip has its main
lobe at 27.9 degrees, the X-terminator at 31.2 degrees. I posted a
current plot for it in:

alt.binaries.pictures.radio

I played with the parameters for the coils, and one coil works just as
well as the 2. Guess it just doesn't look as cool?

I don't disagree with what Mmana says but, there is no antenna
simulation program that can give the definitive answer for how a
antenna will actually perform in a real installation.

In other words when a engineer plugs in his values when designing a
new product he can never just rely on the computer or that design as
the final product. If he is to give performance numbers on the product
he can never use the computed values. He must use the measured
values. The measured value is always the most direct and accurate way
to evaluate a product.

I did notice when I was playing with the parameters on that
antenna, that a small change in the coils or element lengths made a
fairly significant change in expected gain, swr, etc. Most center
loaded, or any shortened antenna is a little more touchy about tuning,
ground and proximity to metal surfaces than a 1/4 would be.
Thanks, was a good Friday project.
