      sky satilite cable extention

      Hello, sorry if this has been asked before but I couldn't find it in search.

      I'm think of rearranging my livingroom where my 2nd box is, which has free sat on the old sky box. It has a single feed coming from the dish, which is not long enough for where I want my TV to be. I've looked it up and there are so many cables extensions, I don't have a clue which one to pick! Another thing is if it will degrade the signal?

      Thanks

      It is a simple choice between replacing the entire cable with a longer single or twin core Satellite cable or an 'extension' which is also know as a "Shotgun cable".

      The cheapest solution is the shotgun cable, but the signal strength will deteriorate a little due to the joint between your existing cable and the shotgun cable. Provided that your signal strength and quality is fine, then this should be perfectly fine. The shotgun cable is basically just a piece of Satellite grade coax with a male and female F-Plug connector at either end.

      The alternative would be to replace the existing cable with a new one. Personally I would fit a twin feed as it would allow you to easily upgrade at a later date if you desire to an STB which records. Of course you would need to be able to safely access the dish.

      There are different grades of coax cable for a Satellite. They come in different thicknesses and grades. Perhaps someone could confirm, but I don't think it would matter too much which you use. Do make sure that you get the correct F-Plugs to fit the cable though. You don't want an F-Plug that is loose.

      I have used this for a new feed to a different room :-

      30m Black Twin Shotgun Satellite Coaxial Cable Lead 4 Sky Plus HD TV Freesat | eBay

      This for an extension in a different room :-

      3M Metre Twin Satellite Sky HD+ Extension Cable Lead Coupler Black Shotgun RG6 | eBay

      This would be fine for you if you didn't want to upgrade to a shotgun cable.

      5M Satellite Sky Extension Cable Lead Digital Coupler Virgin HD Black TIVO | eBay

      Check their other items for sale if its too long / short / wrong colour.

      If I may correct you, the signal will be attenuated by the extra cable length. Attenuation by the joint (if correctly made) will be negligible - probably only 0.5 dB. Attenuation by thin "shotgun" cable is around 0.5dB per metre at highest LNB frequencies.

      This is why SatCure recommends using no more than 20m (total) of WF65 thin cable to connect LNB to receiver.

      Re: sky satilite cable extention

      Can we agree that perhaps both may be correct?

      From personal experience with a shotgun cable, my signal did drop. The total length was less than 10m.

      When I had my 2nd STB installed I asked for the cable to be replaced with a single length and all is fine now.
