I have tried two TVs with 3 different tuners and 2 different antennas, in Brussels. One is an old pocket device with DVB-T. The tuner for the other TV (made in 2022) has these specs:

Tuner/Reception/Transmission
• Aerial Input: 75 ohm coaxial (IEC75)
• TV system: PAL I, PAL B/G, PAL D/K, SECAM B/G, SECAM D/K, SECAM L/L
• Video Playback: NTSC, SECAM, PAL
• Tuner bands: Hyperband, S-Channel, UHF, VHF
• Number of Preset Channels: 100
• Tuner Display: PLL

I’m surprised this TV is only a few years old yet there is no mention of DVB-T/2. A powered DVB-T2 antenna is connected to it. Neither finds any signals when autotuning. Is that expected? Wikipedia mentions a long list of stations for Belgium and some seem to be Brussels based.

Can anyone confirm or deny terrestrial TV broadcasts in Brussels or anywhere in the rest of Belgium?
