With some new builds there can be stipulations put on the owner not to mount TV Aerials externally. Also with new builds TV points are usually installed with the aerial cables running with in the cavity of the walls with the cables coiled up in the loft ready for connection to a new TV Aerial.
The downside to Loft Aerial installation is that you can lose anything up to 50 % of the signal strength when installing the aerial in a loft. Interference from walls, other buildings and trees can cause a huge loss in the quality and strength of reception. Whereas this can be avoided if the TV Aerial is mounted on a tall enough mast, avoiding the buildings and trees.
At Digitec-Aerials.co.uk we also use the Log Periodic TV Aerials for mounting on masts outside or on the roof/chimney. The reason we choose to use this aerial is it is just a great all rounder picking up a great signal even in poor areas, and with the increase in interference it picks up less than other digital aerials.
