[UK-CONTEST] Rotators, Grease and Yagi's

[Andy Cook, G4PIQ]

Adrian,

For the elements, only use grease if it's aluminium loaded grease. Don't use
the copper loaded stuff. I did that on one element of a KT34XA once and
regretted it for years. It was a regular source of open circuits due to
electrolytic action until I cleaned it all out.

Hi all
 
Bit of advice from you seasoned contesters...
 
I am building a 14MHz Yagi at the moment, and want to make sure that the
electrical connection between each length of tubing remains good. (Each
element is made up of 5 different sizes of Ali tubing, nesting inside each
other). With that in mind I thought conductive grease ? 
 
The second grease question is what grease would you reccomend in greasing
the bearings in Rotators and Thrust bearings ?
 
Thanks
