[MLB-WIRELESS] pigtails

[Shane Chubb]

Hi all
This is my first post here so these questions are probably old ones.
A friend and I are currently building machines to connect wireless to.  We
have come across a few problems - as I guess all new comers would.  The
wireless cards we are using are Proxim RangeLAN2's which only have a small
antenna on them.  There is however a MMCX connector underneath which can
have a pigtail connected to it.  My question is - does anyone know somewhere
in Australia that sells these pigtails?  I have been able to find then in
the US but feel that postage on such an item would cost more than the item
itself.

I am also hoping for a few suggestions to antenna selection.  We have an old
Austar Sat dish and were going to play with that but from what I read a
parabolic grid may be a better solution.  What's the consensus there?

One last thing.  I have also found some amplifiers and have a circuit to
build your own, but knowing what level of output is required is something i
am unsure of.  The RL2's output 100mW standard, what sort of range "should"
that provide with a nice 25db parabolic?  Is there a formula to work out
power output to range knowing a particular antenna's gain?  the amp circuit
I have here allows 2.2Watts output, however is that level of output legal as
I have seen no products that go above 500mW standard.

A lot of questions I know, please don't feel that you have to answer them
all, I am simply looking for peoples opinions and experiences in this area.

Cheers
