The joists run in the opposite direction to what you assumed so yes there will be a few holes.. and the cables need to come from the corner of the room.
I haven't assumed anything. I'd based my comments on what you wrote, you know, the information that you put in your post. Here, I'll quote your exact lines if you've already forgotten:
So I think the joists are running left to right should they be 400mm apart ? going to be alot of holes !
The emphasis of left to right is mine, but these are your exact words.
Since we only have your picture and description to go off, then it's reasonable to presume that when you say "left to right" then we take it as meaning in the same direction as your red arrow. [ED:
Would anyone else reading this disagree and think that left to right meant in the direction from the camera position to the window?]
The reply was very condescending.... such as "Are you going to repeat the same mistake when the TV is relocated?" & "God knows what coax you've bought from Kenable. Most of what I see there is either the moulded cable junk or the crappy CCS RG6"
Why not offer an alternative ? I'm sure you are very knowledgeable...
Alternative? An alternative to what? You haven't said what cable you've bought.
You've described it as Sky Q cable. Do you mean coax? Do you means HDMI? Do you mean something else entirely? No one can give you an alternative unless we know what you're considering buying. That's made even more pointless after you've already bought some kind of cable.
Incidentally, Kenable's best coax cable appears to be this:
Skytronic "100U" cable with copper clad aluminium shielding. It's not an all copper cable, and why, it's because aluminium is cheaper. It doesn't perform as well. But it's cheaper. It doesn't last as long. But it's cheaper. There's the potential for a bi-metallic reaction. But it's cheaper.
If you were installing coax - and we don't know if you are because you never bothered to define what you mean by "SkyQ cable" - but if you were, the Webro WF100 is what you should be using.
The cost of the cable is pennies more, but as an all copper cable it will live even if the inner gets soaked. That alone makes it cheaper in the long run than having to chip out walls and break in to ceilings because some aluminium-based cable has turned to mush in the presence of a bit of moisture. That's what you learn when you do installations professionally. You learn to look past the product cost to what it will cost to rectify any issue because you saved £1.50 from not buying the best cable on the advice of people who have been there and done it.
I'm off to my next job.
Whether they're needed or not, come hell or high water, you've decided that there are going to be a lot of holes and by God no one is going to prove you wrong; certainly not some guy that does this for a living and who had the temerity to reply for your call for help. What cheek eh?!
