Radome Material

(OP)
Can anyone assist?

I have a need to build a radome to house a two GPS antenna.
The question is to do with the best material to use to minimse signal attenuation.

The choices available are different mouldable plastics:

Polycarbonate
Acrylic,
Exterior quality ABS,
High Impact Polystyrene,
Polypropylene.

Are there any documented charateristics for these materials at L1/L2 (1.2 to 1.6 GHz) frequencies?

Thank you, in advance
Mike T

RE: Radome Material

The above site has a large list of materials with their dielectric constant ranges. Polypropylene looks best per your list...dielectric constant is 1.5 to 1.8(very low loss). I would think weathering and impact info would be considerations also in selecting an appropriate material. I hope this helps some.
