I have an idea for everyone. I have not tried this yet...so if anyone has...and has had issues...LET US KNOW. I have a db420 that we are putting up on a 300ft tower here in metro ATL.
This stuff is not only used on aircrafts, but look down at the very bottom of the page. When shooting "Pirates of the Caribbean", they ran into corrosion issues. It's not cheap. I paid $30.50 for a 32oz bottle. However...a very thin film is used. Working on some duplexers now and will be coating them with this stuff. I need my db420 to be on the 20yr plan. Can't afford for this to go bad, espcially for what it will be used for. The gentleman who turned me on to this used this, used it on his private airplane. Said that it actually "looks" for that corrosin and gets under it. After reading these posts...I may use this stuff on the WHOLE antenna instead of just the connections. 73, Robert www.georgiaskywarn.com
