Been asked by a friend about omni-directional TV aerials. The situation is that their TV aerial is attached to the chimney and the redundant chimney stack is being taken down. There is no obvious other high place to put an aerial and putting it at the front of the house would mean a lot of cabling to the back of the house (where they have their TV). I've read about digidome aerials and have read good reviews on them. Anybody have experience with them. It is in Cardiff and an area generally with good signal, although you can often pick up two transmitters - Wenvoe (South Wales) and Mendip (Somerset). No sure if this is a good thing for omni-directional or not? Thanks in advance for any replies.
