X-terminator antenna
 

http://www.bills2way.com/equip/image...man_sp2000.jpg

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.

Sure they do. You forget that the diameter of the coil makes just as much of a
difference as the number of turns. It's a perfectly legitimate loading coil, but
nothing that couldn't be done with much smaller wire.

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.

You don't even know how to measure the antenna, for the coils give him
the I.D. and the number of turns, not the overall length of the coil
wire, and od.

So I don't include the length of a coil? I take it that a coil of 9
turns 5 inches long is the same as a coil of 9 turns 10 inches long?
You may want to do a little thinking before you post the next time.

Regardless I did give him the ID. If you can't figure out the ID by
the info I gave then you are the one that doesn't have a clue.

The coil gauge is also needed...........So go back to your beer.
You seem to have a better grip of that.

I could of given him the pitch of the coil but that would of totally
confused you. You seem to be confused enough.



Have a confused day

I agree. If anyone has one of those beasts in my area I would be more than happy
to run some legitimate field tests that anyone is welcome to witness.

You didn't give the correct info face the facts. How do you figure the id
when no wire guage is given? Either way you have no idea what the coil
does then if your giving him it in length, plain and simple.
Snip

I'm not even going to bother responding to most of your post. You have
confirmed your confusion by the above comment. Should I spell it out
for you?

The ID is figureable by the dimensions I gave. Just as I said it was.

Given info.................OD= 2.625
Given info................The coils is made of 5/16 tubing.

ID = OD - 2 x 5/16 Duhhhhhhhhhhhh

ID = 2.625 - 10/16

ID = 2.625 - .625

ID = 2

Duhhhhhhhh again

The X-terminator's coils work out to 1.27 uH for the 9 turn coil and 0.60 for
the 5 turn coil. The values of the coils and their positions on the shaft are
consistent with the design of a center-loaded vertical.

For those that don't already know, a loading coil is used to shorten an antenna
while still keeping it's electrical length at 1/4 wavelength. But the antenna is
necessarily less efficient because the coil radiates part of the power, and that
power is lost. Why is it lost? Using the X-terminator picture as an example, you
will see that the wire in the coil is oriented perpendicular to the antenna, so
any radiation from the coil is going to be horizontally polarized, while the
radiation from the antenna is vertically polarized. Some people might think
that's a plus because some people have horizontal antennas, but it's really
useless because it is radiated from 14 different wires (9 turns + 5 turns), and
none of them are in phase with each other. Since there is no receiver publically
available that can receive all those signals, put them back in phase with each
other and add them to the horizontal signal, the power radiated by the coil is
wasted. Nor can a receiver pick out just one signal from the fourteen. Even
worse, the coil concentrates the magnetic flux (just like any other coil) and
directs it right at the roof of the vehicle, which results in more lost power
due to eddy currents induced into the sheet metal. Any loaded antenna is a
trade-off between antenna height and efficiency.

The only difference between the X-terminator and any other center-loaded
vertical is that the former is built for kilowatts (and not very well at that,
as the conductors are chrome plated, so it's RF resistance due to skin effect is
higher than stainless steel, and much higher than bare copper or silver). There
is no way that this antenna will outperform the unloaded 102" stainless-steel
whip.

Tnom's test may or may not have been a sham -- he may have actually gotten those
numbers, but for reasons other than what he presented. Personally, I think the
only thing he tested was his imagination.

No doubt, but a claim by a person, ad or company concerning a product
they are hawking, can never be taken at face value. An educated consumer
will do their own homework, take all the claims, and make their own
informed decision.
Common sense and logic has always held that "buyer beware" is the
unwritten rule of thumb. A fudged claim isn't the same as ordering
something and not receiving such,,,,,,which is what I would refer to as
being "cheated."

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?

higher than stainless steel, and much higher than bare copper or silver). There
is no way that this antenna will outperform the unloaded 102" stainless-steel
whip.

Tnom's test may or may not have been a sham -- he may have actually gotten those
numbers, but for reasons other than what he presented. Personally, I think the
only thing he tested was his imagination.



The X-terminator has its main lobe at bit higher angle than the whip
does. That may account for some of the differences.

Chrome has about the same conductivity that Stainless does, or at
least from the info I found. 3-15% for Stainless, 19% for chrome,
relative to copper.

Ok Tnom, You've peaked my interest. URL?

I think bills two way sells them?

Who makes it?

Workman?

Is this one ok ?

$36.95 SP-5000 X-Terminator V, 1000 Watt Single Open air coil, 1/8"
square Copper wire, 70 inch overall length.

That's not the same one as Tnom is pushing.

It's way beyond that on this group,,,,this is about one who prefers
Chevy, one prefers Ford, and yet another prefers Dodge. The margin of
difference when applied to the average cber will not be noticeable
between the the antennas. The actual "cheating" taking place, if indeed
such a thing is to be found among a discussion forum, are the posts of
malicious and angry origin, unprovokingly attacking one's character by
name, contacting their work, and intentional libelous content of posts.
Of course, we can always add the scumbags that post under different nics
and play both sides of the fence......


I am not trying to play both sides of the fence Twist, you know me and my
CB background. But when it comes to the truth about a product there should
be no "fence" that divides us, only the truth.

Tnom's test may or may not have been a sham -- he may have actually gotten those
numbers, but for reasons other than what he presented. Personally, I think the

I guess picture that I posted of all the antennas I used must also be
my imagination.

Actually it's 62"..........If you can wait a second I'll give you the

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'll have to go through the archives to find the numbers but chrome is
a better conductor than Stainless

The only difference between the X-terminator and any other center-loaded
vertical is that the former is built for kilowatts (and not very well at that,
as the conductors are chrome plated, so it's RF resistance due to skin effect is
higher than stainless steel, and much higher than bare copper or silver). There
is no way that this antenna will outperform the unloaded 102" stainless-steel
whip.

The coils are copper with a chrome plating.................The chrome
does not cause any additional skin effect.
