Having recently purchased a Denon DM38 CD/Dab Unit, I found that the supplied Dab aerial gave variable results where I had the Unit located (by a very thick stone wall in a canted cupboard). In the daytime the signal was fine but during parts of the evening a digital bubbling could be heard under the audio signal.The Philex aerial was very simple to install, unscewing the existing "T" aerial cable and screwing in the F-Connector on the end of the new aerial cable was the work of 30 seconds. The aerial rod screws into the base and sits vertically with a rubberised cover on the base-plate to avoid scuffs. There's a reasonable amount of cable, but I located the aerial immediately behind the Dab Unit in the cupboard where the Unit is kept. By chance,the height of the aerial fits exactly to the top of the inside of the cupboard and is invisible from the outside. So far the aerial is performing very well with 80% signal and no distortion. I'll revisit this review after a few days experience.
