jeromephone 6 Posted April 4, 2020 cca is junk you need solid copper core and shielding . for instance this is from an online supplier RG59/U 20AWG Pure Copper Conductor 128 Copper Braided (95%) 18 AWG X2 Pure Copper Power Cable Share this post Link to post Share on other sites

jeromephone 6 Posted April 9, 2020 https://www.firefold.com/collections/bulk-coaxial-cable is one of many suppliers. the main thing is to stay away from CCA Share this post Link to post Share on other sites
Opeth 3 Posted April 10, 2020 All cables localy are cca. Ccs condactor and cca braid. Why this is important? Because it is very expensive to get it from usa or anywhere esle outsife europe. I mean the delivery cost and taxes import Share this post Link to post Share on other sites

Opeth 3 Posted April 10, 2020 Im based in Cyprus. Usually i install 2mp hdcvi cameras over utp cat6 using video power baluns. But i want to try the rg59. I dont know if i had any problem with rg59 cca for 2 mp cameras but some clients ask for 4k cameras and the balun is up to 4-6 mp support and i think clarity over coax it will be better Share this post Link to post Share on other sites
tomcctv 190 Posted April 10, 2020 Cyprus nice. been asked to supply a outlet there a few times. your right HD analog is limited over cat5. Once over 4mp coax is better for distance. done HD analog over half mile with no problems when looking at 4K analog always pick 4 in 1 cameras and 5 in 1 recorders ..... this gives you the option to use all formats Share this post Link to post Share on other sites
bmw1999m3 0 Posted May 30, 2020 I've used cheap chinese RG59 cable (with Copper Clad Aluminum center conductor) with absolutely zero issues whatsoever. Picture quality always is perfect. Granted my longest runs have only been a few hundred feet, so maybe pure copper is preferred if you're going thousands of feet, but I even tested out a camera on a 1000' spool of the CCA cable and the picture looked fine. Not sure why it gets such a bad rap. Share this post Link to post Share on other sites
Opeth 3 Posted June 3, 2020 No i will not go too much distance. I care only for the quality of the video. You can see the specs of my cable that i had up. Share this post Link to post Share on other sites
jeromephone 6 Posted June 7, 2020 cca gets a bad reputation because it is not allowed on many construction projects. A lot of it does not meet electrical code. Here is a link discussing CCA in a network (Cat5,6 ETC) that addresses some of the issues at least in the US. https://www.flukenetworks.com/content/application-note-copper-clad-aluminum-cables Share this post Link to post Share on other sites
Opeth 3 Posted June 10, 2020 But the contuctor is cupper the braid is cca. I dont think is too big deal Share this post Link to post Share on other sites
jameslandry 0 Posted November 1, 2021 I use KabelDirekt Digital Coaxial Audio Video Cable. I like the connectors of this product because they are of high quality. This cable has 24K gold-plated male adapters, which are resistant to corrosion. Plus, gold is a good conductor, making signals clear from my antennas to my TV outputs.
