Al, Yes, I had thought of the threaded bolts. I have some I am going to use, but in a strieght format with half clamp plates.
My application is going high on a 5.25" leg tower and need some hardware to secure a top and bottom antenna mount. I found some material at this site for SitePro1: http://www.sitepro1.com/?OVRAW=Bolt%20U&OVKEY=bolt%20u&OVMTC=standard&OVADID=4835093522&OVKWID=42106146522 There prices are good and have lots of heavy hot dipped Galvanized. It seems, like in aircraft, if one goes to a radio comm equipment site the prices near double or sometimes much more. Thanks for the info on the threaded bolts. 73, ron, n9ee/r >From: Al Wolfe <[EMAIL PROTECTED]> >Date: 2008/07/13 Sun AM 01:59:28 EDT >To: Repeater-Builder@yahoogroups.com >Subject: [Repeater-Builder] Re: antenna mounting hardware > >Ron, > I've often used "All-Thread" for U bolts and V bolts, you know, the >continuously threaded rod often found at the local hardware store.
