[TowerTalk] Rotor loop coax

[N2TK, Tony]

Had some noise generated on 160M during a breeze. I am shunt feeding the tower. Used a 1.5" tinned braided strap attached to the mast right below the top plate of the tower and clamped to a tower leg. Left enough slack for mast rotation. That quieted down the noise.

>  W3LPL has alerted us to the fact that passive intermod is often

generated within rotor housings, the solution for which is to bond around the rotor. What do you recommend for making the connection to the mast above the rotor? 
 
    I dunno. What does the new N0AX grounding book say? My answer would probably be to use some sort of stranded insulated wire with a hose clamp on the mast and the bottom end connected to the tower - connection type your choice with some anti-oxidant on each end. 
 
    To be honest I've never done this.
