If aluminum were banned from most sites there would not be many systems on the air. It’s only when dissimilar metals are joined that you have a problem and that’s a very easy fix. I may think twice about using a aluminum antenna in a high humidity/salt area these days but I doubt it. Way to many DB Products out there that are working well and stand up a lot better to lightning than fiberglass radome antennas do. You just have to know how to prepare the aluminum antennas before putting them in the air. I know if a DB-410 that I put in the air in 1975, it was used when I got it. It’s still in service today and working well.
I have several DB style folded dipole antennas on my commercial sites without any problems.

FOr this reason very special precautions must be taken in the preparation of connections to it and protection form anything that would compromise it over time (such as moisture or contamination). ----- Original Message ----- From: HYPERLINK "mailto:[EMAIL PROTECTED]"DCFluX To: HYPERLINK "mailto:[email protected]"[email protected] Sent: Friday, August 31, 2007 8:18 AM Subject: Re: [Repeater-Builder] Wal Mart effect makes it to the Communications Hard (feed)-Line industry Correct me if I'm wrong, but when Aluminum oxidizes doesn't it become non-conductive? Which I believe is the reason it is baned from most sites? _____ size=2 width="100%" align=center> No virus found in this incoming message. Checked by AVG.
