What aerial works on Llanddona?
The transmitter broadcasts on Group A with horizontal polarisation. Most modern wideband aerials will receive this transmitter, but a group-specific aerial gives better signal-to-noise where there's known interference. If you're in a known black spot or fringe area, a high-gain Yagi may be needed.
