Hi Joe, the day I took that aerial down was a busy day, come 7pm we were having our grub and realized that I hadn't put the aerial back up, tried the TV and it worked on all channels so there it has stayed, just sheer laziness on my part, we are near the edge of St Austell bay, the transmitter is at Caradon hill, we are part way down a valley so no direct line of site, I doubt I would get a decent picture if it was still the old analog transmissions.
Did you manage to find a way of connecting an external aerial to your DAB radio? Maybe reverse engineer the front end RF stage and fit a coax socket.
When I first saw the picture in your first post I was a bit confused by that aerial design but I get it now, the striping of the outer insulation on the bottom half of the dipole could be to serve as a permanent indicator as to where the choke needs to be wound, I can't think of any other other reason.
Aerials can be a bit of a dark art, there is a lot of tosh on the internet written about them and a lot of tosh discussed about them on the amature bands.
