Lexan is a trade name for polycarbonate.  It's not sold in harware 
stores.  It's what "bulletproof glass" is made of.  It has good RF 
characteristics at least to 500mHz.  Our club has used it for years 
to make hundreds of Yagi's at 420mHz.  It's strong, easy to machine 
and exhibits good resistance to UV.

73, Dennis
