Two antennas, twelve receivers,
zero compromise.
The AS-122 is a dual-channel, very-wideband active antenna splitter built to drive up to six diversity receivers from two antennas. Top-tier linearity (39 dBm OIP3), 1.5 dB noise figure, protected remote DC feed and per-channel RF Peak indicator. Made in France.

Highlights
Very wide bandwidth
From 340 to 770 MHz: high VHF III, UHF IV, UHF V. One unit covers legacy European and US blocks — a single splitter for every tour.

Top-tier linearity
Typical OIP3 of 39 dBm: IMD products stay below the floor even with several boosted transmitters on stage.
OIP3 39 dBm
12 SMA outputs
Two channels × six outputs: up to six diversity receivers from two antennas. The density you need for productions that don't compromise on HF count.
2 × 6 SMA · 6 receivers
Protected remote DC feed
12 V / 200 mA per BNC input, individual current limitation: a faulty active antenna doesn't bring down the other channel.

RF Peak alert
A dedicated LED per channel flags excessive RF input. One glance, no prod interruption — you know exactly when to move an antenna or insert an attenuator.

Reduced consumption
76 mA without active antenna: compatible with a sound-bag battery across a full shoot day. 4-position stainless clip included.

Use cases
Film / series production
Six wireless lavalier actors in full diversity
Two antennas in the grid, six receivers at the cart, every receiver fed by both RF branches. Standard redundancy for demanding sets.
Theatre / musical
Expand an existing HF rack
When a production scales from 3 to 6 HF channels, the AS-122 extends distribution without touching the antennas or recabling the existing rack. Surgical integration.
Event / festival
Cover a VHF/UHF international stage
The 340–770 MHz band covers both legacy and current blocks: one AS-122 follows artists from Europe to Japan with no hardware change.
