i have RG59 cable installed in an office. I want to use it for Cable TV. What connectors do I need to terminate the cables?

I bought some F type connectors but the cable seems too large for the connectors.

rg-8

u want to use rg6 quad shield

so what is RG59 for? won't it work?

RG59 is used only for patch cables in CATV applications. You have more signal drop over length in RG59 than in RG6. In other words, if you terminate the RG6 where it comes through the wall, for instance, you could use RG59 from the wall to the TV. If the distance from the wall to the TV is more than 25 feet, I'd use RG6 as a patch cable, also. I'm not sure what the spec is on the distance for RG59 in this instance, though. We use RG59 over long distances (600' +) for security cameras and monitors. You could probably get by without quad-shield RG6 for most CATV applications (usually specify quad-shield for satellite applications), but I'd probably go ahead and use it just to eliminate interference.

Just my two cents.
The RG59 may have been for an old arc-net network.

Hi,

RG-59 is not just for patch cables, it's just an antiquated cable for CATV applications. It carries a higher dropoff rate for higher frequencies, and also has a larger tilt. You can expect to see about a 10DB difference over 500MHz, if not more.

If you're having a difficult time putting fittings on RG-59 and you have RG-59 fittings... take a look at the shield of the cable. How many layers of shielding are there? If there are more than two (ie. two layers of foil and two layers of braided shielding) then we're looking at RG59QS or general use cable type 59 quad shield.

For standard CATV without any digital services, RG-59 should be perfectly OK... digital services ran over RG-59 will work fine as well, although with shorter distance requirements... and higher input signals.

old arc-net stuff was 50ohm is i recall. rg58/59/6=75 ohm

RG-59 could be used for thinnet ethernet.
Aren't BNC connectors so much fun!

RG-58 is for computer networks (50 ohms)
RG-59 is for TV (75 ohms)
