GRP is a bit complicated for me. The whole project as usual is to be built at near zero cost, usually from what I already have lying around in the garage. I was considering radiating a small signal from a genny and connecting the bare antenna to a receiver to provide a reference level, then putting the pipe over the antenna and seeing if it made a difference, but that will take a lot of setting up, which is why I thought I would see if anybody who is into antenna building had done any experimenting already. The pipe I have is standard white "plastic" waste pipe so hasn't any added colourant to my knowledge. The actual antenna is an active one I found at a rally in unmade kit form, and uses a MAR-X type device, so has to be weatherproof if used outside. I think it is a Howes AA-1 or something, from some time ago.
