Hi guys:
I bought an antenna made up of heavy duty stranded wire and the spacers were
made ot 16 mm black irrigation tubing about 3 inches long and slotted at the
ends about a quarter of an inch. The wire is simply presed in, not even
glued with anything. It has passed a very windy winter and nothing fell out
of anything, so it should be quite stable.
73 and all the best de
Alex 4Z5KS

I have seen smaller irrigation pipe used for drip systems. Not sure
what
the diameter is though. Just a suggestion. It's still black and I'm
not
sure if it's rigid enough.
