I hope you can appreciate it and use it for your practice.


I will be glad to answer your questions.

Hey Kees;
Looks great

I live in an apartment;

wonder if the people in the next building would mind
if I strung one up ;

AH ! F**K em! I'll just do it

Put a Huge " Bush For President" banner on it..
-& a tinny radio playing
"Hail To The Chief
24/7

Yeah !!!

Happy DX'ing everyone!!

Good idea....I could put cardboard cut outs of cumdungeons fish on one
for a beach effect. That would be neato.

Nah...I would hate to ruin what looks like a great antenna design.

I made a nice one up a number of years ago and really wasn't impressed
with it.

Stuck with the wires.

I found that my garage is WAY to far away to use this setup.

Following the formula, I took an average frequency of 10 Megahertz. I
divided into 100, as per the formula. I got an antenna length of
(100ft/10,000,000) = 1 X 10^-5 feet, or 0.00012 inches.

I then thought that this just couldn't be right. I redid it using Meters
instead of feet and arrived at 0.00001 meters length. MUCH BETTER! The
problem now is that the store only sells full length rolls of wire.
Where can I mail order a smaller chunk? Can they just wrap the postage
stamp around it to save shipping costs?

Being ever on the watch for cheap alternatives, what is a cheap way of
relocating the far end antenna support?

I don't want to pay to have the garage moved.

Any insights appreciated.

The Tilted Terminated Folded Dipole ("T2FD") is a broadband folded dipole
antenna design that provides a relatively
stable feed point impedance over about a five to one frequency range. The
antenna
length in meters is approximately 100 divided by the lowest desired
operating
frequency in megahertz. The upper element of the folded dipole is opened in
the
center and a non-inductive terminating resistor of around 350-400 ohms is
inserted.
The bottom element is fed in the center through a 6-to-1 balun for a good
match to
50 ohm feed line.

The antenna is not as efficient as a matched half wave dipole at any
specific
frequency, but it also does not require an antenna tuner for operation,
making it
easy to use. The loss of receiving efficiency is not generally noticeable
in the high frequency range (2-30 MHz), amounting to less than 6 db (one
standard
S-unit) during extensive on-the-air testing.

Here is additional information on the T2FD antenna.

Barker & Williamson actually applied for a US patent (US Patent #4423423)
for their specific T2FD antenna design.
http://www.fact-index.com/t/t2/t2fd_antenna.html

While this may be acceptable for SWL operation, the resistor does not have
sufficient wattage for
any station attempting to use this for a transmitting antenna.

Thank you, but now I have to cancel the building movers.

(Are the numbers REALLY better on this site or is it just a plot by the
copper wire conglomerates to sell more product? g).

=================================================
1. The length of each leg ("A'') from the center is equal to 50,000
divided by the lowest desired operating frequency (in kHz) and then
multiplied by 3.28. The answer is in feet.

2. The spacing between radiating wires ("B") is equal to 3000 divided by
the lowest desired operating frequency (in kHz) and then multiplied by
3.28. The answer is in feet.

3. The sloping angle for a non*directional pattern should be on the
order of 30, but 20–40 is acceptable.
