Does anyone know of a 2m commerical dipole? Cushcraft used to make a 4
dipole phased array for tower use. I only want one.

I know it is a simple antenna to make, but in my case it is something
I have to pay someone to put up (even if it is on an awning over a balcony)
and it has to survive wind and sandstorms, direct sunlight at 3,000 feet
altitude, and 6 months of the year extremely low humidity.

I want a dipole because a beam would be too obvious and attract attention,
and I want it horizontally polarized.

Any suggestions?

TIA,

Geoff.

Do you know how to make a Yagi Driven element?

That is a Dipole...

So you did not read his post, right?

Try to answer his query rather than show your (lack of) knowledge.

Also, post your callsign, if you dare.

Look at this horizontal loop.
http://www.aesham.com/uhf/m2-antennas-2m-ho-loop/

Very similar to a dipole and I think it is omni directional where a dipole
willbe directional.

John - no reason to be offensive.

The OP asked if anyone knew of a manufacturer of a dipole antenna.
Any antenna 1/2 wavelength in size can be considered a dipole antenna.
The problem with horizontal polarization is that you need to get it at least 10' above everything else in the neighborhood to get it to work.
That does not leave you with a stealth option.

Too many people moves into a house and after they move in, they say, oh and by the way - I would like to continue to practice being a ham.
To which the local housing /zoning board says NO!

So people gets all kinds of bright ideas on how to hide antenna's.
The telephone commercial for Verizon comes to mind - can you hear me now!

NO - no one that I know of makes a horizontal Dipole antenna, due to the fact that most people are too cheap to even buy a antenna these days.

The antenna I have good luck with is the Diamond V2000 - but that is probably 6' tall...
Another good vertical antenna is a Diamond X 510 - which is probably 18' long.

All you need is some plexiglass, a bunch of stainless steel screws and nuts and bolts. A couple of sections of old aluminum tube - even a elderly persons walker would probably produce enough aluminum to make a decent antenna. Or a old lawn chair.
One piece to the left, another to the right, a SO connector, some Permetex Loctite Blue RVT, a couple of pieces of copper wire and a dab of solder and a couple of ring terminals and you would have yourself a antenna.

Find someone with a antenna analyzer to adjust the length to 146.550 and you would be set.

A even better solution would be a HALO antenna or a Moxun Beam - which some people might call a Sqaulo - since it is rectangular.

ARRL antenna book is your best friend in a situation like that!

While it is a Dipole, the impedance will not be very near 50 ohms. Some
Yagi driven elements can be adjusted for 50 ohms, but some can not. Also
when removed from the beam, the dipole may be too short to be resonate at 2
meters.

If you can find a PAR Electronics Omniangle loop I'd recommend that.
It's within .5 dB of omni and horizontally polarized. I believe the
design was Motorola but it ended up some other places including PAR. I
remember them calling it aperture synthesis or something like that. It
sure doesn't look like an antenna that would be omni but it's closer
than anything else I've seen. His site is still up but you can't order.

http://www.parelectronics.com/faq-omniangles.php

I have a 2m version and could send you all measurements. But the
"matchbox" is sealed and I'm not going to cut it open. It may be only a
choke because it does state that a balun is part of it.

Unfortunately part of his antenna business was taken over when he
retired (?) but the Omniangles are no longer manufactured. You might be
able to find a used one. They were made for HF through 432 or maybe 1296.

Goeff-

Ralph's suggestion appears to the best so far.

Another approach might be to use one of those "Make a dipole out of a
pair of mobile whips" adapters, but you would still need to find quarter
wave whips. In other words, it is not a "commercial dipole"

One problem you are faced with, is that the dipole needs to be in the
clear, and therefore may be too obvious for your needs. It may not work
very well if it is on an awning with a metal frame.

Speaking of metal frames, one stealth antenna might be the awning frame
itself, if you can find a way to match it to your feedline. Perhaps a
gamma match would work at the midpoint of a horizontal portion. Again,
not a "commercial dipole"!

Try Sinclair Antennas, Geoff =- they specialize in commercial antennas,
duplexers, etc. Google them under Sinclair Antennas Canada and they show
up.

If you want an excellent commercial product,
there's Kreco antennas:

It will be the last two-meter omni you'll have to buy.
