Installing Sat cable ...help needed

[Loopie]

I need to drill and install sat cable at my new house, but the walls are filled with Rockwool sheets, Can I just drill through this or do I need a special tool or something. Also will the cable feed through ok?

thanks for any help!

Hi,

My walls are like yours, and I got the cables and drill through OK.

I drilled the hole 15mm ish diameter and taped the cable to a bit of metal coathanger so that I could push it through. It took a few attempts to get the cable right through because it gets mis-aligned after going through the outer brickwork.

Also best to use a cover plate on the outside to prevent rain running in.
