[TowerTalk] Rotor on AB577

[Dana Roode]

Hi all,

I have a AB577 mast and I need to put a rotor on it - if someone out
there has done this and would like to share your approach with me,
please drop me a line.  I built an adaptor I am not completely
satisfied with out of the top piece I got for the 577.  Does anyone
know if other top pieces for the mast are available somewhere?  For
example, a mast adaptor to take the 5" diameter mast down to 2"?
