hi neil,
fairly straight forward i think, have 5 bits to masterlink, 4 of the 5 bits are against external walls so cables can go round outside of house to loft, other bit requires a cable to be run round the skirting of a room before going outside (no more than 10m), plus side is it's in the kids play room which has a wooden floor with beading so i'd imagine the beading can be lifted and the cable run underneath ?
