RonR399 0 Posted June 6, 2013 I need to move a cctv monitor a few feet(25-30). the existing is using BNC connectors and I do not know the existing cable impedance. can I use RG-6 cable with F fittings and then use adapters from F to BNC without any video issues??? how important is impedance in this case??

bigglebowski 0 Posted June 7, 2013 The coax you will be using will most likely be the same impedance of 75 ohms, so it should not be that important. You can freely interchange BNC, F, RCA etc.. as needed. Of course you do want to minimize using splices and adapters if you have the choice. If you were to use a cable of another impedance then you would need to use impedance matching transformers to convert it back to the same impedance, but this would not be typical. At short distance like using TV coax in the place of a video grade coax (copper clad center conductor and sheilding) should be OK. Share this post Link to post Share on other sites
