Anti-oxidant grease question
How do I apply anti-oxidant grease to the junction of two metals? Do I put
a dab of grease on each mating surface then clamp the metals together, or, clamp the metals together and smear grease on the outside? I have a Yaesu FT-857D and an ATAS-120 installed in my truck -- I have had a problem with the ATAS-120 -- my FT-857D would not recognize the antenna. After checking every possible problem, I made a discovery. Using my ohmmeter, I found there was continuity between the antenna mount and the body and frame of the truck, but, there was no continuity between the antenna connector and the antenna mount. The connecter is a VHF Type M mount; the threaded portion of the connector passes through a hole in the antenna mount and is tightened to the mount with a big nut. There was no connection between the connector and the antenna mount, thus, there was no connection between the outer shell of the antenna connector and the truck frame and body. I removed the big nut that holds the antenna connector and used emery paper to sand the surface of the nut that contacts the mount, and, I sanded the part of the mount that contacts the nut. When I re-installed the antenna connector, the antenna works perfectly. The problem was a bad ground between the antenna connector and the antenna mount because of oxidation on the two mating surfaces. I have found a source of anti-oxidant grease that's used on electrical connections and I will put this stuff on the connector-mount junction to prevent further oxidation. Here's the question: Do I loosen the nut and put grease between the nut and the antenna mount -- similar to putting thermal grease between a heat sink and the surface of a transistor -- or, do I tighten the nut and smear grease on the outside, not on the mating surfaces? I suspect I should put the grease on the mating surfaces between the nut and the mount -- loosen the nut, smear on grease, tighten the nut. Thanks. |

The anytioxidant has to be in intimate contact with the metal surfaces before they are clamped together. Here is a site that tells how to use one version, Penetrox-A. The details are about 1/4 of the way down: http://www.inspect-ny.com/aluminum/alreduce.htm#1A |

Thanks again. 73, Joe |

For aluminum, (which oxidizes almost instantly in contact with air) they recommend coating the surface and then doing the final abrading, so the fresh surface has no contact, at all, with air, before the joint is assembled. It sounds a little like trying to make a dry joint under water. |

I noticed that in the instructions you sent and I figured the rapid oxidation of aluminum was the reason. |

Another product that works very well is Lawson 59933 Copper Anti-Seize
Anti-Corrosion Compound http://webapp.lawsonproducts.com/web...?itemNum=59933 This is the same product that comes with a Butternut vertical antenna. It consists of a synthetic grease base, copper, thickener, and rust inhibitor. It can withstand temperature ranges from -65°F to 1800°F, which should be adequate for most ham applications. John, N9JG "J. Mc Laughlin" wrote in message ... I am a big fan of Penetrox-A. It is sold in a small squeeze-bottle that is just right for most tasks. It is also a good anti-galling material to use when screwing SS to anything. |

Well that figures.... just like so many on line places to buy things they
have everything there but the PRICE!!! They expect me to return or fart around trying to get some one to put a price on everything I want to buy?

I did buy a can of the stuff from them, but note that a can will last a
lifetime for you and ten of your friends. Just fill out the order on the web page, and one of their sales persons will phone you and give you the price. If you don't like the price, you don't have to complete the order. As I recall, it may have been about $25 for quantity one. The call back and the shipment were both done promptly.

Ok thanks. That looks affordable then. With out prices its hard to tell
these days. I have an ol AR-10 Ringo that I used back in the 90's for 10 m DXCC and has been in storage for several years. I think putting some compound on the joints may make it work as new again. I been delaying this task so I could get it up and have it work right the first time. Thanks 73 K4TWO Gary "John, N9JG" wrote in message news:XRkHf.760597$x96.380669@attbi_s72...

Be careful about trusting my memory. I bought the can several months ago,
and I didn't save the invoice because I knew I had more than a lifetime's supply. When you do find the price, go ahead and post it here. "Mr Fed UP" wrote in message ... Ok thanks.

Come on folks. This stuff is cheap compared to maintenance. A 1 minute
web search finds Noalox at Home Depot stores for $8.95 for an 8oz. bottle. Penetrox is about the same price but not sold by Home Depot. Larry, W0QE |

Sorry ... whine wasn't about the price... it was about advert's with out any
prices. They want our business but too lazy or dumb to post prices with the ad's Big radio stores included check most of the ad's in your handy QST and you can see that they make YOU work to find prices. Maybe Wal-Mart will get into radios , then the price competition can start LOL My apologies to those who know all and have deep pockets. If you don't like the postings.... well if your that smart I don't need to finish. Thanks 73 K4TWO Gary "Larry Benko" wrote in message ... Come on folks. This stuff is cheap compared to maintenance.

I must have mis-understood your whine but my comment was not directed to
ward anyone. From my point of view, unless I enjoy talking about connections that are unreliable (I don't), the price of Penetrox or Noalox is really cheap compared to having to disassemble connections and clean them.

Not to mention, that Home Depot (and Lowes), have even smaller bottles ,
4 oz,$6.00 , and think even 2 oz tubes, for even less! And a little goes a long way!

Well for those of us who don't get around so well, it was nice to have a
product name to ask for. Home Depot had an even smaller tube 1/2 oz and I got some steel wool to buff things up first. both less than $6. I probably would have been an hour finding that tiny tube hanging in the store. With more days behind me now than ahead.... and hoping my next antennas will be new ones. It should last me till my end. Kinda like buying a tube of water pipe compound once you use it once the rest hangs around forever. LOL Thanks for brand name to ask for. Saved lots of steps I can't spare these days. 73 K4TWO Gary "Jim - NN7K" wrote in message et...

There are a lot of us with that condition! Time and physical demands have become important considerations on projects. And the increasing memory problems that make it harder than ever to find where I put things...
