very small antenna

[mc-20]

Hi Jess, Looking for a small (pack-away in a suit-case and going to bahamas
on a cruise line for vacation antenna.)  I found three on the Yahoo search
that looked good. the buddiepole, the Ventura, the miracle whip

each one claims to have all band and each one says has at least some gain






........................
It's basically a mediocre receive antenna and transmit dummy load.

I currently own the Buddipole and the MP-1 from SuperAntennas. Both  
offer good performance and quality design in a small package.  
Recently, I did a QSO on 20m at 12W SSB with my K2... the OM was  
mobile in Austria... :-) I receive a good report !!!

And the beauty.... you can mix piece of one antenna with the other  
one... they all use 3/8 24 for the threading.... you could even  
invent new antenna... combine this with an analyzer and you are in  
business !!!

I have wanted a set of magnetic paddles for about a year now to use with my
K1 and K2.  I decided to try to make my own and after a few weeks of
designing, I just completed a set.  I used rare earth magnets instead of
springs.  It is constructed using stainless steel and aluminum.  The top is
black anodized aluminum and I used gold contacts.

A picture of the paddles can be seen here:

I really like the feel that I get with magnets instead of spings.  Pretty
smooth.

Beautiful job!  Did you use the magnets to attract or repel?

If they attract, then the force decreases as you close the contacts.  If
they repel (if you do this you need two magnets for each side, of
course), then the force increases -- like a spring.

I personally prefer the attractive mode because it gives a 'clicky' feel
which I like.

What did you use for pivots?

Jess, you should also look at the PAC-12 from Pacific Antennas.  Packs
smaller than the other two (Buddipole and MP-1).  And does very nicely on
all bands.

Jeff, those are VERY, VERY nice paddles.  They look commercial.  Maybe you
should go into business.

I'd go with the Buddipole over the Miracle Whip every time. At least it's a proper dipole.
I've not heard of the Ventura.

Consider also the MP-1 from Superantennas.  Any of these are best  
used with a tuning device such as the Tenna-Dipper.

[k6dgw]

Took my KX1 on a cruise from Ft. Lauderdale to Los Angeles thru the
Canal in April.  I learned a few things:

1.  The Captain and not the CEO of the cruise line runs the ship.  The
CEO said "Hell No, you'll screw up the navigation, endanger the
passengers with radiation, and probably start a fire."  The Captain (OK,
the Jr Officer he sent) said, "Ok but only from our 'balcony' and not
public spaces, and please don't remove any paint.  And don't even think
about using any of the ship's antennas."

2.  The "balcony" is really more like a "shelf."

3.  The "steel window" on the "shelf" through which you can watch the
ocean, turtles, and dolphins is about 6' x 6' (2m x 2m).

4.  A disassembled MP-1 in your bag looks a lot like a pipe bomb on the
airport x-ray.  I wear braces on both legs and I'm toast at security
anyway, so I opted not to add to the inevitable problem and left the
MP-1 knockoff at home.

5.  Buddipoles are bigger than the "shelf."

6.  It's hard to string up 26' (8m) of wire in the 6' x 6' (2m x 2m)
"steel window."  OK, it's nearly impossible.

7.  If you succeed in stringing up the wire in the "steel window," you
will become part of the antenna, causing the SWR to vary wildly as you send.

8.  A few thousand metric (or any other kind of) tons of steel between
your "shelf" and "steel window" have a fairly substantial attenuation
effect on signals from the other side of the boat.

Just my observations ... YMMV.

[Ron D'Eau Claire-2]

Those are good observations, Fred.

The Captain of a passenger vessel doesn't have any leeway about using the
ship's radio gear or antennas, even the spare antennas. They are all an
integral part of the Safety of Life at Sea (SOLAS) regulated gear and must
not be used for anything but their stated purpose. Even old-time Radio
Operators (SPARKS) on ships who were Hams could NOT use the Ship's gear or
antennas for Ham operation, even spare antennas they were personally
responsible for maintaining. Those who had Ham gear on board had the
Captain's permission and a completely independent antenna system, rig and
power source (they could plug into the ships "mains" but could not use the
radio batteries). Sparky's advantage is that he had some options for
stringing a wire that you don't <G>.

There are a lot of interesting ideas for antennas on large ships, including
some really bizarre ones that I'd love to try such as a wire from the
fantail that connects to a metal plate that drags in the water below, but
they all require access to parts of the ship not normally available to
passengers. About the only practical thing that comes to mind is some sort
of telescoping whip that can be clamped to a rail or port opening. For a
ground, a piece of metal or foil taped to the wall or deck would form a
capacitor through the paint to the main hull of the ship.

I think I'd just enjoy the sea air, view and the experience. That's what I
usually end up doing on a trip anyway <G>.

A couple of other points--

In addition to the captain's permission, one must have a license (or  
CEPT permit) for the country in which the ship is registered when  
operating on the high seas.  When in port, the same is required for  
the country in which the port is located.  Most cruise ships  
operating in the U.S. seem to have Bahamas (C6) or Panama (HP)  
registration.  The Bahamas will issue reciprocal licenses while  
Panama honors the IARP.  The ARRL web site has full information on  
licensing requirements.

One can also use a counterpoise running back into the cabin, at least  
on the higher bands where the length of a suitable λ/4 wire will fit.

See the hfpack.com antenna shootouts for the Ventenna, Pac-12, and
Buddistick.  You won't find gain differences between them, just
mechanical and flexibility differences.  The Miracle Antenna you
mentioned is in a different class; see the facts on the site.

I thought Ron, W7AC, very effectively answered this.  As I recall he  
suggested the PAC-12 which I heartily endorse.  The Miracle Antenna is a  joke
compared to something like the PAC-12, or just about any other reasonably  
constructed antenna.  The Buddipole is "the Cadillac" of portable antennas,  but not
quite as portable as the PAC-12.  Vern Wright, W6MMA, makes some  excellent
portable antennas as well.  Vern is a master at designing and  constructing
antennas, so don't overlook anything he has to offer.  I think  his MP-1 and MP-2
are excellent portable antennas, which I have used with great  success from a
variety of portable locations--primarily motel rooms!  The  only requirement is
that you be able to open the darn windows!  So, take a  close look at the
PAC-12, and the Super Antenna offerings, and I would strongly  recommend you pick
from those.  Forget about those antenna ads that blow a  bunch of smoke up
your butt about how "teensy tiny" they are.  The two I am  suggesting aren't very
big either, but they have substance, and have some  theory and quality
construction to back up the claims.  There have  been some antenna "shootouts" which
back up my recommendations.  But if you  have a fair amount of extra room in
that suitcase, the Buddipole will fit--you  can't do much better than that
antenna for portable operation.

Hello Jeff,

    Very nice looking paddles.  Would like to see the insides,though.  
Would it be possible to take the top off and shoot a pic of the
innards?  If its too much trouble, I'll understand, I just wanted to see
if I could steal a peek. Hee Hee

As of this morning, I have received over 100 emails concerning the my iambic

There is no way I can respond to each individual email, so I consolidated

Nothing has to be commercial, unless it's easier and cheaper in time and
effort to go that route.  Got the poles, the wire, trees, tuner... a wire
over a tree ALWAYS works better than a 7 foot loaded vertical over no
radials.  On the other hand, I can walk around with an MP-1 and keyer
paddles fastened on a radio and operate on the move.  As you can see from
the pictures at HFPack, some folks have really elaborate walking-about
antennas, not that mine looks less silly; an antenna sprouting from one's
belly _is_ a bit unusual.
