Topband: tower vertical

[Bob Kupps]

Hi I have decided to put up a 40m tower to use as a transmitting vertical for 1.8mHz out away from in between our other towers and where I can run 1/4 wave radials all the way around, and will probably use locally available 12" steel sections with a conical-type pin base. I would like to insulate the base in order to make it easier to detune on receive (this will be located in the exact center of our 8 circle rx arrays). Has anyone used HDPE or similar to make a homebrew base insulator for a tower monopole? Any other comments about the need for a base insulator also welcome.
