6000W 3-way FM band PTFE splitter/combiner set

Description

6KW (6000W) 3-way pallet amplifier combiner

Make your own 6000W amplifier or transmitter with these heavy-duty 3-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 3 identical amplifier modules of any rating from 0 to 2000W. 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.

Noter: Utilisez du PTFE coaxial/semi-rigide pour effectuer les connexions, des câbles appropriés sont ici.  Câble main-bendable semi-flexible de 0,250 pouce de 50 ohms est un bon ajustement.

Important: Gardez des pistes très courtes, chaque millimètre compte ! Tout câblage des palettes aux combinateurs doit être symétrique (câble coaxial de même longueur).
