Cheers for that - not sure I follow everything you've said just yet; but the materials aren't expensive, so will give it a go.@Thirsty If you can 'turn a screwdriver' as they say, then you will find this job very easy.
First work out how much cable you actually require, and DO NOT use 'aerial' cable as suggested above ( whatever that is, I'm assuming it's standard 75ohm impedance coaxial cable) but rather you will need Sat100/ RG6 etc. or similar.
Then visit your local TV/Sat shop, buy :-
1X F-type screw joiner/coupler
2X F-type Connectors (make sure screw-on type so no need for crimper)
Length of Sat cable required, practically all retailers will cut to length.
1X Box of Clips
And 'Voila' you're all set.
The only thing you have to be careful with is the termination of the F connectors, making sure that the outer and inner conductors are not left touching, as one 'stray' strand of the outer screen can cause a short. This is the single most common mistake made and it will NOT work if a short is present as low voltage is fed through the cable to power the LNB and also to enable polarity switching.
Have a look at a few Youtube vids and you're good to go.
That cable linked to is Sat. cable and has different characteristics than 'ordinary aerial cable' mentioned above, ie. frequencies used, attenuation, dB loss etc.I am sure they are not the highest quality cable. However, I used them without any loss of signal strength or quality on a Sky+ system. It was convenient and all connected up within minutes. I used a different brand but it is not currently available (https://www.amazon.co.uk/gp/product/B004802I44/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1).
But of course it worked ! It's Sat cable.And I was merely pointing out that it works and it is very convenient and user-friendly!
And how does he control the STB (Set Top Box) left in the other room? I'm assuming you mean HDMI and 'hdni' is a typo.You can buy hdni cables up to 2 metres long and extensions to double it. Would this be an easy plug and play solution if the cable fitted under a door ?
No problem, you need a suitable length (allow a couple of metres extra) of satellite co-ax cable (sat100 or RG6 or similar) and three pieces of hardware :-@SparkRite - I need your help again if you don't mind.
Local hardware store doesn't stock this stuff & rather than traipsing around on sunny days, I'll order online.
Just want to be sure I get the right things.
Attached is photo of cable which goes into Sat box (or will be in a minute!)
So do I have this right:
I need a cable (RG6?) x metres long, one end of which needs a connector that looks like photo to go into sat box and the other end needs a connector that joins to the existing cable?
Sorry couldn't figure out how to attach a photo earlier & then was out for the day.No problem, you need a suitable length (allow a couple of metres extra) of satellite co-ax cable (sat100 or RG6 or similar) and three pieces of hardware :-
2 X screw on type F-connectors and 1 X screw type coupler and don't forget a box of suitable cable clips for neatness.
BTW. don't see any pics ?
PS. Just to add, what maybe an option. If you are moving closer to the dish, measure and see if the existing feed is long enough to reach the new position. If it is then simply remove the end F-Connector, pull the cable back out through the house entry point and re-route to new entry point/room, re-fit F-Connector, connect to box you're ready to go, happy days !
