Antiference UDF420DC FM/DAB/UHF/IF 'F' Masthead Combiner
The UDF420DC is a unique combiner with four separate inputs to allow FM (88-108MHz), DAB (217-230MHz) UHF (470-862MHz) and satellite (950-2150MHz) to be combined together.
It has two designated outputs, output 1 is a wideband output that covers from 88-2150MHz which is intended to feed the main viewing area. The signals are then triplexed out by a suitable wall plate. Output 2 is VHF only covering a frequency range from 88-230MHz. It's purpose is to feed directly into the VHF input on a distribution amplifier, enabling the radio signals to be distributed to all the outputs conveniently whilst reducing the need for additional combiners, thus incurring less insertion loss.
The UDF420DC combiner has the facility to provide line power to a masthead amplifier via a switch which enables a 12V DC regulated supply. The line power is fed from the LNB input on the digibox which provides 500mA for the LNB as well as providing power to a masthead amplifier.
Frequency range: FM 88-108MHz, DAB 217-230 MHz, UHF 470-862MHz, SAT 950-2150MHz
Insertion loss: FM < 1.0dB, DAB < 1.0dB, UHF < 1.0dB, SAT < 1.0dB
Outputs: Output 1 = 88-2150MHz, Output 2 = 88-230MHz
DC Pass: UHF - 12V 100Ma Switched, SAT - 14/18V DC 500mA
Out of band rejection: FM > 22dB DAB, DAB > 25dB FM & > 30dB UHF, UHF > 30dB DAB & > 30dB SAT, SAT > 30dB UHF
- Improved filering rejects out of band interference
- Fully screened masthead with built in F-box spanner
- Proven weatherproof housing, mast or loft mounting
