What if the filter doesn’t resolve the interference?
In the majority of cases, the at800-approved free filter will resolve interference caused by 4G at 800 MHz and enable you to continue receiving and watching Freeview as normal. For a small number of viewers, the filter may not restore an acceptable level of TV reception. In this situation, we may be able to provide a different type of filter. If this does not work, we will look at other solutions such as re-aligning or replacing existing TV aerials; improving cabling; or, as a last resort, moving you to another service, such as free-to-view satellite television. at800 engineers are trained to provide advice on how we can best restore your TV service.
