Yes Mehmet, you can use either. Personally I prefer 'copper clad steel' or alloy since it has the strength of steel and the conducting properties of copper, while the copper also protects the steel from oxidizing. Another common name for this wire is 'copperweld'. You can get this from most wire suppliers and large amateur suppliers. The older open wire telephone lines use the same type of wire, though of fairly heavy gauge. It is stiff and a bit hard to work but will stay up forever. My first antenna was made from this telephone wire which I scavenged when they replaced the old wire on our farm. Good luck, Bill

A lot of the old open wire phone lines used galvanised steel wire, which was usually well rusted when the took it down. I got about 7500' of #10 copperweld that was used for telegraph lines that ran along the train tracks. Sulphur dioxide from the old coal burning steam locomotives would eat up steel wire in no time, but the copper cladding developed a green patina and lasted for years.
Later on, someone gave me several thousand more feet of #8 copperweld. I had already used up most of my #10 on various antenna projects and a ground radial system for the 160m inverted L I had up before building the tower.

Hi Rasid! How did you make out with your multi-band long wire antenna project? Is this wire for it? Hope to work you on 40M soon. It was fun working you last year with WB3HUZ. For anyone not familiar with Rasid in Turkey, here's a video he posted of us working him on 40M. Starting at about 0:25 seconds is the QSO with him. http://www.youtube.com/watch?v=TvrMV6q5LhsLater - Tom, K1JJ

Use an "AM Courtesy Filter" to limit transmit audio bandwidth +-4.5 KHz, +-6.0 KHz or +-8.0 KHz when needed. Easily done in DSP.

Hi Rashid
How about using the steel wire as a "messenger" wire. with the copper wire spiraled around it (maybe 1 turn per meter)?
Best regards Stu

I picked up a big roll of TV cable last year at Dayton. The vendor told me it was RG-6, but it looks like RG-6 on stereods. The coax is almost as big as RG-8, but typical RG-6 construction with the tinfoil shield under a sparse braid. It has a messenger wire, which I may rip off if I don't use it suspended between supports.
I can't tell for sure if the messenger wire is bare steel or if it is zinc plated. It is covered with plastic, but I am wondering if exposed parts will rust.
