Drilling holes for coax?

|Hi all, |I have an existing sky dish connecting through the gable wall into my |loft where digital coax feeds down to several of the rooms (hat of to |the the builder for this - saves having black cable strung around the |outside of the house). I'm adding a quad lnb to my sky dish to connect |1 or 2 other rooms. Since all the cabling will come through the same |part of the wall is it best to enlarge the existing hole to accommodate |all cables (will end up being a bit of an ugly hole) or make separate |holes for each cable adding those neat little sleeve/collar things to |each (maybe several holes will look weird?). If I go for one hole I |guess I can just squeeze some sealant in finish it off a bit neater.

Besides sealant remember to have a drip loop on each cable, to prevent rain seeping inside on the outside of the cable.

As well as that good advice, it is advisable to drill holes at a slight angle downwards outwards, only a few degrees, to prevent any water ingress from reaching the inner leaf of the cavity wall.

That's a good one! If the top of your drill is parallel to the drill bit axis, then tape a cheap spirit level to the top of the drill to make assessment of drill level easier.
