[TenTec] OT: cleaners, etc

[Duane Calvin]

One small correction - steel wool is not recommended because it will leave
small particles of the steel wool on the aluminum, and embedded in it.  Wire
brush or Scotchbrite are the best choices.

Whether new or reused, all antenna connections, especially telescoped tubing
need to be cleaned. The antiseize greases (I've always used NoALox or
PeneTrox, but there are many others) designed for aluminum do work.
Scotch-brite is an excellent burnisher. You can also use 000 or 0000 steel
wool, but be sure to remove any oil residue from the aluminum after
burnishing. When I took my Mosley Pro 67 down after 15 years in the air,
every (yes every one) connection slid apart easily. That grease works. 



I have bought used antennas and had to fight them apart. No wonder they
didn't work any more. Cleaned and treated with anti-seize they all worked
well and when it was time  to take them down, the job was easy. More
importantly, the lack of oxidation provided proper operation. 



Check the electrical department of your local Home Depot, Lowe's, or
whatever home builders company is in your area. They will have what you need

But before you make the new connections, use Scotch-Brite or a steel wire 
brush to burnish the oxide off the aluminum and IMMEDIATELY coat it with 
AlumiNOx or whatever the equivalent aluminum oxidation prevention grease is.

Do all mating surfaces this way.  I learned this working for a company that 
manufactured power line connectors for Al wire.  I assume that what is true 
at 60 Hz is also true at RF, tho I don't know that for sure.  I've done this

with my antennas and have not had a problem with them.

AlnoOx aluminum wire connection grease at the connections and junctions.
