Doug, I use "Penetrox A"R (made by Burndy Electrical) to assemble antennas and such. It's available from ham sources (AES, HRO, etc) or commercial vendors (Tessco, Hutton, etc).
I'm not sure of the conductivity of Lithium Grease, but Penetrox has a known level because it is primarily Zinc suspended in a petroleum base... As far as being weather resistant, it still gets all over everything (including me) each time I service the antenna - and mine has been up 7 years now. ;-) Mark - N9WYS -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of n3dab Sent: Tuesday, March 17, 2009 7:59 PM To: [email protected] Subject: [Repeater-Builder] Intermod. question A recent post concerning intermod created by rusty bolts, washers, etc. caught my attention the other day. Someone suggested using Lithium Grease on and between the components when assembling them. I understand the logic behind the suggestion, but I'm wondering if there is any other grease product that would be suitable and might hold up better to exosure to the sun, rain, etc. (something as heavy or heavier then wheel bearing grease) and still have the electrical conductivity of the litium.
