Several times when I scanned for DVB-T signals in the UHF band from home I saw some very weak signals on several frequencies. Too weak to make out anything other than that the signals are very probably DVB-T as the radio scanner does not pick up a thing there (for as far as I know FM receivers cannot pick up QAM signals). The DVB-T receiver I use has a small external antenna (simple half-wavelength wire), so to get more signals I will have to use a good antenna. Buying something is expensive and it is to me much more interesting to build something myself from scrap materials. Most promising seems to be Alan Yates' Laboratory - UHF Log-Periodic Array so I'm browsing my scrap electronics for materials to build this.
