Mercury AMD02 2-Way VHF/UHF Distribution Amplifier with DC Pass

The Mercury AMD02 is a 2-way VHF/UHF distribution amplifier that splits a single aerial input to two outputs plus one full-gain output, delivering 20dB full gain and 12dB per split output. Separate VHF (47-230MHz) and UHF (470-694MHz) inputs allow the unit to handle terrestrial TV and radio signals from dedicated aerials or a combined feed, while an integrated LTE filter blocks mobile network interference in the 694MHz+ range that can disrupt Freeview reception.

Designed for smaller domestic installations where an aerial signal needs splitting to two or three rooms, the AMD02 fits in loft spaces, behind wall-mounted TVs or on shelving near the entry point of the aerial cable. The DC pass function allows satellite control signals to pass through the unit when paired with a Magic Eye extender or similar device, so Sky boxes or Freeview boxes with IR extenders can still send remote control commands back through the same coaxial cable. The side-mounted F-type coaxial terminals accept standard coaxial connectors and the unit includes two F-type adaptors.

The fully screened metal housing reduces signal leakage and external interference pickup, while surge and short-circuit protection prevent damage from transient voltage spikes or wiring faults during installation. The 1m mains cable connects to any standard UK 230V socket and the compact 135 x 70 x 45mm footprint allows the amplifier to be mounted in tight spaces. Maximum output level of 94dBuV and noise below 3.8dB ensure stable signal delivery to connected equipment without visible degradation on Freeview HD channels.

Product Manual

What's the difference between the split outputs and the full-gain output?

The two split outputs (TV1 and TV2) each deliver 12dB gain, while the full-gain output delivers the full 20dB. The full-gain output is typically used for the longest cable run or the room requiring the strongest signal, while the split outputs handle shorter runs to secondary TVs.

Does the LTE filter affect normal Freeview channels?

No. The integrated LTE filter blocks mobile network frequencies above 694MHz, which fall outside the Freeview UHF band (470-694MHz). All standard Freeview and Freeview HD channels pass through unaffected.

Can I use this with satellite signals?

No. The AMD02 is designed for VHF/UHF terrestrial aerial signals only. Satellite signals operate at much higher frequencies (950-2150MHz) and require a dedicated satellite distribution amplifier or splitter.

What does DC pass allow?

DC pass allows control signals (typically 9V or 12V DC) to pass through the amplifier in reverse, enabling devices like Sky Magic Eye extenders or remote control IR extenders to send commands back to a set-top box via the same coaxial cable that carries the TV signal.
