Today I measured the difference in loss (dB per 100 ft) between solid copper (SC) center conductor RG-6 vs. copper clad steel (CCS) Quad-Core RG-6 coaxial cable. The difference is not significant unt
Yes, and you can see this difference in mfr data sheets that are sufficiently detailed (Belden, for example). The differences are greatest at the lowest frequencies. Note also that copper clad alumin
Hi Mike, Obviously I had computers on my mind... Yes, of course I meant to say quad-shield RG-6 CATV cable. I'll provide the manufacturers and part numbers in a subsequent e-mail, but its just typica
Steel, being magnetic, is quite lossy at RF. OTOH, aluminum at RF is only 28% lossier than copper. However, no RG-6 (AFAIK) has a copper clad aluminum conductor. Rick N6RK _________________ Topband R
I successfully use 100s and 100s of feet of copper clad steel RG-6 in my 160m 4-square receive setup with a pre-amp at the station. Copper clad steel works for me. Doug "Think of all the ways you can
I posted earlier on the list (31 January 2011 ) problems we had with some cheap ebay "satellite cable" CCS RG6 that I was using on a long run to 160m Beverages. The 250m reels came from different sup
Hi Doug, Quad shielded RG-6 with a copper clad steel center conductor is an excellent choice on 160 and 80 meters as long as the cable lengths aren't very long. Outdoor rated quad shielded CCS RG-6 i
At KC1XX we also have a 1500-foot feedline run to one of our lowband receiving antennas. We use RG-6 with copper clad steel center conductor, but we install a preamp right at the antenna to compensat
Several topbanders asked if I would measure the DC resistance of the solid copper and copper clad steel center conductors of the RG-6 coax for which I published the RF loss measurements. I also measu
hi Frank et al. preparing our last year's CR3L contest activity in the CQWW-CW, we wanted to try a remote RX-antenna to work in-band multipliers as DM6V in the WAG-contest at DL5AXX's qth... naively
Uli, A very important lesson about CCS RG-6 has been communicated to topbanders by you and several others who have had bad experiences. Thanks for taking the time to describe your unfortunate experie
Its easy to use an MFJ-259 to quickly check cable loss, using its cable loss mode. Its more accurate if you build or purchase a simple 50:75 ohm broadband matching transformer. The 259B uses 1/2 of o
I have been watching this thread with interest, I am preparing to put up a receive array and it will have to be some distance from the shack. Is there a brand of RG-6 that someone has tried that is r
I'd call Commscope quite dependable, first class cable mfr. It used to be one of the Bell companies. I've met their eng'rs at industry trade shows. DX Engineering sells a flooded version of their RG6
Commscope, Times and what ever else quality distributors such as Tessco carry are what I suggest. Also see about buying from the local CATV installation contractors. Carl KM1H I have been watching th
