Topband: [Bulk] Shunt Feed - Insulated Elements on Yagi

[Grant Saviers]

I'm considering insulating elements on large yagis and would like to 
understand pro's and con's of various boom to element plate insulating 
materials - RF insulation, physical strength, creep, uv resistance, 
etc.  These raw material properties are easily found, but have some had 
longer term in use experience worth sharing?
