Currently using this to connect from radio to amp. Very good quality with all solder points connected correctly. A little pricey but well worth it. I am running a Galaxy dx 949 on a 13.8 volt 10 amp power supply using this coax to connect to a RM Italy kl-503 which is connected to a 13.8 volt 36 amp power supply and then to a 75 foot run of rg-213 (also from copper) into a Solarcon A-99 mounted at about 35 foot on my shop roof. I can pretty much talk to whom I please with this set up. ALL OF THIS GEAR CAME FROM COPPER!
