Given the price of Cadwelds and the high number needed for an extensive tower grounding project I am interested in more cost effective alternatives. I know some folks braze their copper strips and or

Patrick, if you do a google search for welding copper there is a pile of info there. 73, Gerald K5GW In a message dated 4/25/2014 4:49:32 P.M. Central Daylight Time, patrick_g@windstream.net writes:

My Tower guy wants to CadWeld my copper to the legs of my AN Wireless tower. This worries me. Warren W7WY _______________________________________________ _____________________________________________
First... reply-all seems to be broke. On subject, mechanical fasteners are entirely adequate for grounding and have the advantage of not permanently altering the material of the legs. David Robbins K

I'd pass on CadWelding directly to tower legs. CadWelding melts a goof portion of the base metal and alloys it with the copper and the Aluminum in the CadWeldinf material. It makes a very good electr
I would agree with everything in that post except for the part about drilling holes. I own an AN Wireless heavy duty 70 foot tower, and every factory brace on it is held fastened to the legs with 5/1

I would not be overly concerned with corrosion from drilled holes. The zinc will still protect exposed metal to some extent and you could always apply cold galvanizing to the hole. I have had to elon

Mechanical fasteners may or may not remain tight through heat cycling, freeze/thaw cycles, and possible corrosion which is why they need to be inspected and potentially touched up periodically. This

If you get really uptight about your connections consider this... The proscription against welding the rebar is a rebar strength issue. Just extend the rebar a bit past its "standard planned length"
