Where To Position

Shrubs and trees, building and hills in the direct path of your antenna may weaken the incoming signal and cause reception problems. If you cannot see the transmitting station, experiment by pointing the antenna in different directions. You may receive a stronger signal reflected off obstacles.

Generally always go on top the roof as high as you can go And the bigger the pole and the antenna the better.

Antennas work much better without a roof in the way of the transmissions but antennas can still work reasonably well in lofts provided your signal strength is reasonable or, preferably, good. In medium or poor signal areas we do not recommend antennas in lofts, but some people have no choice as there may be planning restrictions on outside antennas or access problems. Bearing in mind the loss in signal caused by the roof it may be advisable to go for a slightly higher gain antenna than normally recommended for an (outside) antenna in your location.

There is no such thing as a in-roof antenna, there is only an antenna built to go outside which may work in a loft if the signal level in your area is sufficient. That said, some antennas are more suitable for loft installations than others.
