Telamon,

One of the more 'exciting' stories concerning the BroomStick
Antenna in the Middle East. This Guy built a 18Ft Long/Tall
BroomStick on 4" PVC Pipe. Plus, he had a 750 Ft Random Wire
Antenna connected to the Top of the BroomStick Antenna !

Hello - He had a 750 Longwire Antenna [.]

I've seen you mention this before, but, as I recall the story, the 750
foot longwire was an existing antenna. One would assume the guy knew
how the existing longwire performed and would not be raving about the
broomstick if the performance were not significantly better than that of
the longwire alone.

Admittedly, the whole annecdote needs significantly more information to
be able to draw any kind of legitimate conclusion about the longwire or
either of the broomsticks. And it would have been nice if he'd used a
bit more scientific method and a lot less "kitchen sink" in his approach
to antenna evaluation. But, barring further evidence, I don't think it's
valid to completely discount the broomstick by assuming the longwire was
doing all the work.

I'm not saying the broomstick is a wonder antenna, just that there is no
clear evidence in this annecdote to shoot it down.

It is better if you're in a cabin in the woods.


It's not better if you're in a hotel room, though.

For hotel rooms, loops are pretty good. Most will fit in a suitcase,
and they're less likely to pick up RFI than a broomstick or whip.

I suppose if you expected to use it often, you could make one in the lid
of your suitcase or attaché case - though these might be a little more
interesting than you'd like at airports.

Delightful observation on both points! It *could* make for a very
intersting (and possibly quite effective) antenna,and it *could* make
for a world of grief in airports! Shazam!

I have experience with interesting equipment at airports- my 7030+ is
set up as an "ultimate portable", and the X ray machine shows a cabinet
within a cabinet, and a passle of battery packs and related circuitry
jammed inside the larger cabinet.

Whatever antenna I'm bringing goes in the suitcase, but I keep a short
antenna with the radio so I can demo it for them.

He made a base loaded long wire.

Ah!

quite true..

In hotel rooms,( or the hotel rooms I've been in )

I've found wrapping wire in a spiral round a 1 liter plastic bottle & setting
it on the windowsill, then leading the signal over to the radio helps;

- When venturing into airports, remember that your luggage will be searched
* thoroughly *,
and the batteries taken out of All electronic devices..
So anything in Memory Goes away

Since this, I just write 'em down or travel with a copy of M.T.

You just made yourself the equivalent of a Hamstick. There's some
frequency out there at which it's going to work like gangbusters! At
that frequency it should outperform your other antennas. But as you get
away from that frequency, whatever it is, it will be worse than a
straight wire antenna.

I just completed an atempt at construction of the "broomstick" antenna
the plans for which were found on the internet. I used a 84" x 1.5"
pole, a 14" aluminum pie pan, approximately 100" of 14/2 solid household
wire. I followed the instructions as closely as possible in the
construction. To my dismay the contraption provided absolutely *no*
increase in signal strength that I could discern. Before I call this a
flop I wanted to ask a few questions of the group:

1. Has anyone else built one and found it to work?
2. Does it really matter if the wire turns are actually touching each
other or can the be spread by up to 0.5"?
3. As much as I hate to show my lack of antenna theory knowledge, does
the type of wire covering matter? The instructions said to use 16 PVC
covered wire but I could not find this description on the available wire
at my Home Depot.
4. I made contact with the wore to the aluminum disk by stripping 1" of
the end and wrapping it round a nail between the pan and the end of the
stick such that when the nail was driven in it pressed the disk against
the bare conductor. Is this valid?
5. Does it actually matter if the feed line is connected to the whip or
the external antenna jack of the receiver?
6. How much wire should I use ideally? As much as I can fit on the
pole? Enough for a quarter wave at 5MHz?
7. I have to assume that the benefit of this sort of antenna must be
only nominal since if it worked as well as a stright wire, it would be
more widely used. How much of an increase in received signal strength
should I expect?

It took me the better part of a day to gather the supplies and construct
it so I hesitate to let the project go until I hear from experienced
users that it is not worth it. I welcome any suggestions or critique.

Best,
-Al A.

I have a broomstick up in my attic feeding a dx394 in the basement. It works
OK, much better than the 20ft of wire on the whip (inside). Got a 100' wire
antenna Im going to put up this spring.

LW,

Not really, the 18 Foot tall PVC Pipe 'wire wound' Broomstick
Antenna at these Shortwave HF would efectively appear to be a
[Hollow] Metal Tube acting as a vertical antenna element.
( A piece of Copper Pipe. )

The better arangement would be to take a piece of PVC Pipe with
a "T" on Top. Start with a piece of wire, and have a single
loading coil wound for a specific frequency; and then run the
wire up to the "T" and through it and out horizontally for as
many feet as you can run the wire.

Indoors - Stick the PVC Pipe in the corner of a room and have
the top wire circle the room at near the ceiling level.

Simply - A Folded Inverted "L" Antenna with a Loading Coil
designed for a single target Shortwave Band.

If this is then your thing - The 'build' a series of them
if you need coverage on more bands.

It's not worth it. Lousy antenna. I have one out on my patio waiting for me
to reclaim the wire off it. A 20 foot longwire out performs it.


DnB,

That's why they sell those small 23 Foot Roll-Up Antennas that
can Clip to the WHip Antennas of most AM/FM/SW Radios.

What Works... WORKS !
