In reply to Mike Brookes, Church Stretton: these problems at your location probably had nothing to do with either your system, mis-tuned , nor a problem at . As you are most definitely located in what engineers refer to as a fringe area for uhf tv signals from the Winter Hill site. These fringe areas are especially susceptible to what is known as tropospheric propagation, which particularly becomes a factor at this time of year during days of high pressure weather with fog/frost. This phenomenon can last for minutes, hours or even days at a time, and signals which are normally at good strength can be attenuated to virtually nothing even when using the highest aerials & amplifiers! Conversely, very often at these same times, distant UK transmitters can often be tuned in (which would normally not even register an ounce of signal on your TV). The only real solutions to here would be to retune your equipment to a nearer (which would mostly avoid these tropospheric effects), but then you would obviously lose the North regionality, or you basically just tolerate these rarer 'weather' effects and keep your TV of choice.

To 'Anonymous' above: probably best to keep each telescopic rod at 45 degrees, i.e. at 'half vertical, half horizontal' so to speak. This will allow for a variety of different polarisations used by RTE sites, or even lower powered independent sites. The broad sides of the rods should of course be facing towards , & it probably goes without saying a multi-element outdoor FM (even without ) will more likely bring you greater success. By the way, to the other users on this particular page, I can definitely confirm that is transmitting on UHF 23 & 26 only (NOT channel 39 as stated) & I understand the tech. to be DVB-T with MPEG4
