Two antennas, eight outputs,
under OLED control.
The AS-84 is an active combiner/splitter with selectable filtering, built for wireless racks, film sound bags and broadcast installations that demand reliable diversity. OLED monitoring, antenna zoning, protected remote DC feed — every RF decision in the palm of your hand. Made in France.

Highlights
OLED monitoring
High-contrast display showing per-channel RF level, antenna DC-feed status and filter configuration. Full diagnostics at a glance.
RF per channel · DC status · filter
Antenna zoning
Select PORT 1, PORT 2 or both combined per channel. Cover a split stage, a venue or two zones with a single rack.
PORT 1 · PORT 2 · PORT 1+2
WB / NB filtering
Wideband 470–700 MHz for versatility, or tunable narrowband (50–70 MHz) to reject DVB-T, LTE and intermodulation in crowded RF environments.
WB 470–700 · NB 50–70 MHz tunable
Protected remote DC feed
Regulated 12 V, 200 mA per port, current-limited with fault detection. A dedicated LED per BNC shows exact active-antenna status — no more blind diagnostics.

Front-end linearity
32 dBm typical OIP3 and input-to-output isolation beyond 80 dB: even under dense HF transmitter load, intermodulation products stay below the floor.
OIP3 32 dBm · NF < 2 dB

Use cases
Film production
Feed 4 diversity receivers from a sound bag
Two active antennas on the belt, eight SMA outputs, NB filtering to reject nearby cell towers. One-click zoning when the scene moves from one stage to another.
Broadcast / theatre
Distribute two antennas across a full wireless rack
Cover stage and backstage with a pair of directional antennas, drive remote DC feed from the OLED, and monitor RF level per receiver without tearing down the rack.
Live / festival
Secure RF reception in a crowded environment
Switch to tunable narrowband filtering, read per-channel levels in real time, spot a worn cable or a failed antenna instantly through the DC-feed LEDs.
