Relocating Sky Q main box

Our dish is located at the back of the house and I need to relocate the main box to the front of the house. The cleanest way of doing this is running a new cable up along the back of the house wall on the outside, through the attic and back down the front of the house. On the outside I think it's about 30metres or thereabouts.

I've spent the last few hours reading up on what the best cable to use is and most on the Sky forums are saying WF100 but it's hard to find across this in shotgun form.

I'd really appreciate being pointed in the right direction here. This seems too cheapto me: https://www.freetv.ie/black-mini-shotgun-cable-50m/

Thanks very much for any suggestions
