Broadcast two carriers,
near and far, in parallel.
The ATH-200 is a hybrid transmission station for one or two HF carriers (30–500 mW per input, 100 MHz – 1 GHz band). Each input is simultaneously routed to a nearby coax antenna (2 dB typical insertion loss) AND combined onto the optical output to feed a distant antenna via AFB-350. Optional 2nd optical output at order time. 1U rack form factor, universal mains power. Made in France.

Highlights
Near and far, in parallel
Each connected transmitter is routed directly to a nearby coax antenna AND combined onto the optical output toward a distant antenna (AFB-350). Double simultaneous coverage.
Direct coax + distant fiber
1 or 2 carriers
Inputs for one or two carriers (30–500 mW per input). Optional extension to two fiber outputs, to cover two distant zones from the same station.
2 carriers · optional 2 fibers
2 dB insertion loss
Only 2 dB typical loss between input and direct coax output: the nearby output stays at level with no extra preamp. Fiber takes over beyond that.
Coax: 2 dB typ.

Use cases
Stage IEMs + off-stage IEMs
Broadcast a live mix near and far simultaneously
IEM transmitter → ATH-200 → stage antenna over coax (2 dB loss) AND distant antenna via AFB-350 over fiber. On-stage artists and off-stage technicians receive the same mix, no delay.
Multi-zone intercom
Cover control room, stage and exterior from one rack
Intercom + IFB → ATH-200 → local coax antenna (control room) + two parallel AFB-350 (stage + exterior): three coverage zones, one central emit station.
Sports event
Connect press and permanent stadium install
Fixed-install ATH-200 in the tech rack → coax antennas in the press-box zone AND fiber antenna in the opposite stand: coherent coverage across an event that moves around the stadium.
