Well, I was under the impression this hobby is wire-less.
You mean I've been doing it wrong for 40 years ?

Sorry to bewilder you Dave, but when it comes to LF wire aerials I really
am
a complete newbie.
Although I've been licenced for over 40 years now, I have spent all my
time
up the "other end" of the spectrum.

So, no I haven't really got 100m rolls of stranded cable kicking around in
my shack. I do have a 6 foot dish, a couple of 30 foot long 2m yagis etc,
etc, so any wire needed for a 136 aerial I will have to go out and buy,
and
before I did that I wanted to make sure that I wasn't wasting my money on
the wrong stuff, plus wire shops are few and far between down this neck of
the woods.
The only wire locally (nearest 15 miles) is CB & TV coax, twin and earth
electrical and electric fencing wire, anything else is a 120 mile round
trip
to Cork city or arm and a leg postage.
Thanks for the tip about loudspeaker cable, that might be possible
locally.
73, Tony, EI8JK
