antennas

[Shaun Oliver]

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.

As described, this would so obviously not work as an effective antenna
that I feel I must have misunderstood what you were trying to describe;
or someone has hijacked your PC.

One would expect it to behave much like an equivalent length of coax.

According to the list guidelines, this subject is not off topic.

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.
