Re: [Repeater-Builder] Re: Di-Electric Grease
The proper thing to use is the PTFE Teflon lube that comes with the antenna. At least it's supposed to come with new antennas... It looks like silicon, but it's not.

Re: [Repeater-Builder] Re: Di-Electric Grease
I may have missed part of this discussion, but if the grease is put in the connector or under black tape, how is it exposed to UV sunlight so that it will destabilize? My understanding about silicon grease is that it can change the dielectric constant of the connector. I have used silicon grease in the connector and the antenna would not tune until it was cleaned out. I also understand that over time that silicon grease will "creep", that is, it will move between the metal to metal connection of the connector and form a thin insulating layer.

Is bether than getting water in conection as water will not displace this Grease. My vote is this Grease is almost as good as SEX if I could remimber what it was like. Oldmax Dale ( N8SAC ) Yahoo!

Re: [Repeater-Builder] Re: Di-Electric Grease
Hi all. I to have used the dow stuff for years. It is 4 Compound I believe it is the same as the goop that andrews supply with their hardline connectors. Just about all the outdoor connectors that I have used over the past 30 years has had it in the connecting faces as well as inside the body. I have used it in the electrical joints on my boat trailer and on my 4 wheel motor bike(this is where faults apear in time). Cheers from down under. Ps I am making a portable repeater on 460mhz 10/15 watts and would like not to use a diplexer can you advise the solution. Maybe a tx groundplane with a solid disk and have the rx ant hanging directly below ie 180 degree to each other. The ch spacing is 500khz. I would use a foil or at least a double sheilded cable for each feed.

Re: [Repeater-Builder] Re: Di-Electric Grease
Quickly learned to slather it (or similar) on NMO antenna mounts -- O-rings, lock-nuts, springs, whip-set-screws -- anything threaded that might need to come apart; years later -- vehicles looked like he77, mounts like new. Surprising little rusting around the hole, too. DC-to-daylight... Good stuff, Maynard. ;-) ~/ RSG /~ n8sac wrote: .I have also used in PL-256 Conections for years in Ham Radio on all bands Some say not to use above VHF but I haven't had any problems.
