Hi, I did a design using passive video balun for transmite video analog signal. I found a type of UTP wire that is more cheap, but isnt 100% copper, is 70/30 aluminiun and copper, the wire said is Catergory 5E. My question is if i can use it wire with video balun for video and if the resistance is higher because sometime use the same wire for power supply. Best Regards
