Satellite cable - maximum length

[scene]

I'm looking to run a satellite (coax) cable from my dish to my new extension.

Thing is, I think it's going to end up about 30m long :exmark: Is this a problem?

daveh is your man but according to the geezer who fitted my second dish that could be too long, depending on how many bends there are in the cable. I can't actually remember how long mine would have ended up being but in the end he stuck a second dish on instead, which was nice.

30m is fine providing you use good quality 75ohm double screened cable like Webro WF100 for example (though any CAI Benchmarked type 100 cable will be fine). WF100 is good for, and i regularly use it for 50 - 60m runs, though over that would consider using the thicker WF125.

Thanks for that

I suppose the double screened makes sense as well, as this is going to be sharing ducting with the cat6 cable (as per my other thread) - so does that mean I can get away with UTP for the CAT6 - or should I go with FTP - or will I need triple screened coax...

The double screened cable will be fine, provided it's the xx100 type cable i mentioned above which has copper braid over copper foil screening, as opposed to so called 'low loss' satellite cable as it usually has inferior steel braid over mylar (metalised PVC film) screening and high losses despite it's name.

FWIW i've got miles of WF100 and CAT5e UTP running in the same conduit/trunking/bundled together all over my house, and haven't had any issues with interference.

Thanks for all that daveh75 8) I've got some cable ordering to do...
Not to mention some compression clips and a compression crimping tool :type:

It's also worth amplifying the signal before going through the long cable

e.g. using a Easy Fit Satellite Signal Amplifier Booster & Patch Lead

I found it made a huge improvement to my reception. I also use a 5m QED coaxial tv cable which is great (have adapters to make it work for satellite)
