By 2012 (end of the digital TV switchover), many outdoor aerials will require upgrading in order to receive digital TV signals. When choosing an outdoor aerial it is important to evaluate the digital TV strength in your area and the location of the aerial. The 48 element aerial is the most powerful outdoor aerial in the range and can be used in all signal areas due to its high gain. Ensure you purchase good quality cable and fittings to maximise reception quality.
Got me one of these in the Belfast store which had just been reduced last night. The same product has two different bar codes. Look out for the bar code that ends in 5817, these are reduced to £7.00 the others remain at £40.
