TV Aerials Fitted in Preston

For a while now there has been a quiet revolution going with the new kind of digital TV Aerials being installed in Preston. For years and years, aerial erectors in the local area have been fitting poor quality television aerials to peoples homes and thinking no more of it. However, the problem they have tarted to find is that the poor quality aerials are beginning to perish pretty quickly in the bad weather. Also, whereas with the old analogue signals, the aerials could be tuned to get a better picture even when the signal was beginning to reduce. With the new digital signal, this does not offer this kind of adjustment and so, instead of the picture quality slowly deteriorating, it will completely unwatchable as the digital signal for Freeview is either on or off. When a signal is becoming weaker due to water ingress in the aerial and coax cable, the viewer of the TV will lose groups of channels completely, such as all of the BBC channels or the ITV channels.

These are very robust, the don’t often succumb to water ingress and they also, act as a high gain aerial. They in appearance don’t have a balun of back reflector unlike most other aerial designs and so have a reduced wind load, making them less likely to be blown down during a storm compared to the other aerial designs. Due to aerial companies wanting to give their customers a guarantee to cover both the equipment and installation work, they are starting to use better quality coax cable as well. The CAI approved coax cable will last decades in the open, and can be relied on to last a very long time.

Is the new Digital Signal a Better Solution for TV Aerials?

With the advent of the digital signal, it isn’t a bad thing that poor signals will deliver no watchable TV, since as an industry it means that aerial fitters are having to up their game when it comes to providing and fitting the equipment that they use. Having to give guarantees to their customers is also making them provide better quality and longer lasting equipment to them also. TV Aerial Services are one such company that has been established for a few years now and they offer a lifetime guarantee on their equipment and installation work.
