Ah, sorry if I misinterpreted what you meant. Regarding "proper" galvanization, such things CAN still be had. There are two kinds of galvanized products these days: "flash" galvanized, which is usually not very useful outdoors, and "hot dipped" galvanized. The hot-dipped type tends to look "crusty" and dull gray in color but will hold up for decades. All the utility hardware is done this way and it lasts. You can get this type of galvanized hardware in big box hardware places, it will look dull gray (NOT shiny).
A lot of the shiny stuff people think is galvanized is actually a cadmium playing and it rusts pretty quickly outdoors. -Bill > -----Original Message----- > From: k...@myfairpoint.net [mailto:k...@myfairpoint.net] > Sent: Monday, December 15, 2014 11:49 AM > To: Bill Wichers; Topband > Subject: Re: Topband: ground radials & conductivity > > Bill, > The Back Stay rod was to show with correct galvanization of the 1920's they > stood up well. > The parentheses was a reference to wire used in antennas.
