Shaun,
It sounds like you're wiring the shielded twisted pair like an
extension of the feed coax. Remember, anything that's shielded is
designed to keep the signal traveling on it from radiating. But, I may
be misunderstanding your description. While there are several antenna
designs that use coax as a radiator (see:
http://www.hamuniverse.com/bazooka.html), their "claim to fame" is broad
band, low SWR, not size.
There are many limited space antennas (see this Google search:
http://www.google.com/search?hl=en&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&q=antenna+design+%22limited+space%22&btnG=Search),
but YMMV (You Mileage May Vary). I stumbled across this "small" antenna
that seems to have some good reviews: http://www.tak-tenna.com/ . At any
rate, those should give you some ideas about antennas.

Hi all, I'm sorry to bring up this off topic subject, but I have a
question for those of you that like to cobel together your own antennas.
I have here some wire htat has 2 center cores and an outer brade. this
in turn is covered by an outer foil and then insulated. what I'd like
to know, if I were to attach some coax to one end of this wire, center
core to center core and brade to brade, etc, would it be sufficent to
pass as a dipole or am I kidding myself? basically wwhat I'd like to
know is if it will work. I'm strapped for space here so intend on
aquiring some electrical piping and coiling the wire around it and
sealing it from wear and tear by the elements. if you could, please
kindly write me off list as I don't want to clutter the list up too
much with off topic posts. my apologies for this one as I wasn't sure
where elseI could take this one.
thanks in advance.
