Television cable

[briwire]

There doesn't seem to be a forum on TV wiring so i'll try this one.

I have a V+ box in my living room and an additional box in my son's room upstairs. The cable goes from the entry point near the living room TV, upstairs to his room.

He's moving to another room upstairs and I want to transfer his connection to the new room.

I don't know if the lead and connector can be pulled back through the holes in the joists, so what's it like to dismantle then remake off?

The alternative is to extend the exisiting lead using the correct in-line connector, run a lead up into the attic and down into his new room.

Are the cable and connectors readily available? Is there anything special about them? Will there be any detriment to the signal with the extra 7 or 8 meters of cable? Do I need a special tool to terminate?

Far too much trouble tbh.

Get a decent splitter and do it that way. Then you can have the signal in both old bedroom and new bedroom. Connectors aren't so good.

I use CT100 to distribute my signal around the house. Bear in mind that each joint will cost you 2-3dB, but the cable box should handle the loss ok.
Personnally, i'd put a splitter in the 'old' bedroom, run some CT100 up like you say into the loft and down into the new room. You 'may' get away with the rubbishy coax crimp connectors that just squeeze on the end of the cable with pliers, but i use f-connectors and a snap-n-seal tool to do the job right. The tool costs about £15, then you'll need a cable cutter and some f-connector, with coax adaptor to plug into the tv.

Hope it helps.

You can get twist on F connectors that work perfectly well:

i suppose they would do this the OP's requirements.
£1.99 each though eek!
Mine just fell off the one and only time i tried them, they failed the tug test.
