HI justnosleep,
A warm welcome to our community 
I just wanted to pop by and let you know what you're options are in terms of relocating the cabling/equipment:
* You can have one of our engineers relocate the wiring/equipment, we can book this with you if you decide to go ahead with this option. Not only will we relocate the wiring/equipment, we will make sure any signal adjustments required is done, and we can ensure a fully working service for you.
* Some people have found that using devices like video senders etc very useful, since the last time you tried this out the devices may be more reliable than what you've previously experienced. Although I am not totally familiar as to how this is done myself, but there are other posters here who have done this who maybe can advise of their knowledge and recommendations.
* If you're planning to purchase the cabling yourself and rewire this can lead to complications not just for yourself but for others in the nearby area. If the length of cabling is changed or it's the wrong grade of cable then this can affect the signal feeding your service and also have a knock on affect to nearby services as well. It's not a method I would recommend doing for anyone as your service can be degraded as a result.
If you want to arrange an engineer appointment with me then just give me a shout. There is a cost of £99 if you decide to go ahead.
Let us know what you decide.
