4000W 4-way FM band teflon splitter/combiner set 4KW (4000W) 4-way pallet amplifier combiner

Make your own 4000W amplifier or transmitter with these heavy-duty 4-way combiners. Assembled and tested, ready to be installed. Heavy duty design, large and sturdy. You will need one input board, one output board and 6 identical amplifier modules of any rating from 0 to 1000W. Output combiner must be bolted to a heatsink with some airflow for cooling, input combiner can be bolted directly to an aluminum enclosure as it does not heat-up much. Surface mount construction makes installation easy.

Technical specifications:
- 87,5 - 108MHz
- Impedance: 50 ohms
- Max power per module: 1000W
- Max combined output power: 4000W
- Max input power: ~14W (3,3W per module)
- Ultra low loss Teflon PCB; tightly controlled dielectric constant.
- Size output board: ask
- Size input board: ask
- Distance between inputs/outputs of separate pallets: 75mm
- Input/output combiner boards are both shipped with aluminum substrate

Note: Use PTFE coax/semi-rigid to make connections, suitable cables are here.  0.250 inch semi-flexible hand-bendable 50ohm cable is a good fit.

Important: Keep leads very short, every millimeter counts! Any wiring from pallets to combiners must be symetric (equal-length coaxial cable).
