I have a loft aerial – will this affect me?
Roof aerials located in the loft or in an attic rather than on the roof can often provide unstable reception. If you have previously had good reception, have received a postcard from us and notice new TV interference, call us. If 4G at 800 MHz is diagnosed as the potential cause of the interference, and you are responsible for your own aerial, we can send you a filter to fit yourself, free of charge. Full instructions are included and we can provide further advice online and by phone.
In most instances, fitting the filter will resolve any interference from 4G at 800 MHz. If it does not resolve the interference and, if you are eligible, we can arrange for an at800 engineer to visit your home, at no cost.
