I am trying to cook up a simple collinear antenna for 1800 MHz and one for 800 MHz.
I'm following plans which involve bending coils into copper wire and then enclosing the copper wire inside a length of white pvc electrician's conduit.
the plans are for 2.4GHz though. they regard the pvc conduit as transparent to the 2.4GHz signal, it's just there for protection & to give rigidity.
is white pvc electrical conduit, the kind sold by sparkies factors everywhere in the uk, 16mm internal diameter, as transparent to 800 & 1800 MHz as it is to higher frequencies?
or should I use different materials for the casing
