DVB-T/T2 and 5 V for active aerials

Menu → Setup → Tuners, Scanning & Reception → Tuner Configuration → enable terrestrial reception. Country and region select prepared scan frequencies. DVB-T2 requires a suitable frontend; changing the region cannot turn a DVB-T tuner into DVB-T2 hardware.

Direct aerial connection

Section titled “Direct aerial connection”
Aerial to the DVB-T2 input shown in the lower connection example
Use the lower path for DVB-T2. HDMI then connects the receiver to the television. Enlarge wiring diagram ↗
  1. Connect the aerial to ANT IN or the shared DVB-C/T2 socket.
  2. Enable DVB-T/T2 and select country and region. If the region is absent, use All or an appropriate general frequency list.
  3. Enable 5 V for active antenna only as required by the connection.
  4. Scan; if reception fails, test a known local multiplex directly.

When should 5 V be enabled?

Section titled “When should 5 V be enabled?”

The supply named in the OpenATV tuner form is 5 V, not 4 V. Actual availability depends on the receiver.

Connection 5 V setting
Active aerial explicitly designed for 5 V over coax On if its load is within the receiver limit
Passive aerial Normally off
Aerial with separate power supply/inserter Follow its wiring plan; do not add another supply without checking
Direct cable TV outlet Off
SPAUN TAR 5 before a hybrid tuner On in the DVB-T section to select the aerial branch; details and DC blocking

5 V cannot amplify a passive aerial. An active aerial does not automatically benefit from more gain: excessive signal level can also reduce reception quality. Check the receiver, accessory and aerial current limits together.

T2 parameters and picture formats

Section titled “T2 parameters and picture formats”

Manual scan offers frequency or channel number, bandwidth, DVB-T/T2 system, modulation, code rates, guard interval, transmission mode, hierarchy and the T2 PLP ID. Use Auto where supported and appropriate, otherwise follow operator data. A PLP is a physical data pipe in the T2 transmission, not a programme number. See the scan reference.

A T2 lock does not prove that the video can be decoded. Encryption and codecs are additional requirements. PLP and driver limits can restrict sharing between recording and live TV: single tuner.
