I think that most here know that even the best (rubber duck type

is still only 1/2 of a real antenna (no real ground plane) and
adding
a
wire, hanging off the ht and connected to the outside of the antenna
connector improves performance.
What I was wondering is.
Has any one tried doing the same thing with something like foil
tape
going
around the outside of a HT? Or possibly a spring or a couple of
springs
connected to the antenna connector?
Btw it's a 5w Icom T2h so its pretty big for an HT, I commonly get
in
areas
where I can key up the repeater of choice but skip in and out
sometimes.
My only other choice would be a small yagi (kind of hard to fit in
a
suitcase)

You may not need the gain of a yagi but could still easily do a
collapsible
dipole that would fit your briefcase. TV rabbit (aka "bunny") ears
come
to
mind as a donor antenna -- replace the twinlead with 50 ohm coax (and
a
choke balun). And for a portable antenna with a short feedline,
RG-174/U
is
mighty convenient (buy a BNC-to-whatever patch cable & snip off the
uneeded
end). If you buy a longer BNC/BNC patch cable, you can cut it in
half
and
make two (different) antennas.

Forgot I had used TV rabbit ears during a month long stay up in
Syracuse.
The TV was on cable but still had the rabbit ears that cme with the TV.
These were made for use with coax so they are just a cable connected to
the
telscoping antenna. Bought an F to BNC adapter at Radio Shack and was
in
business. Ive used pieces of wire pinned to curtains.

The coaxial cable was likely a 75 ohm variety... but would be close
enough
to 50 ohms so the rig would drive it. Apparently, it did for you! ^5

YEah, the cable on the antenna was pretty short, not more than a foot.
Fortunately I had a 6ft piece of rg58 with BNC connectors.
Thanks all,
I had thought of a few of the options you all suggested. I was seeing what
you all could think of or have done.
I also wonder if its possible to realistically run 2 ducks in phase?
I would like to avoide the 19 inch wire hanging down.
Thanks
