CWS ByteMark manufactures these Baluns based on Dr. Jerry Sevick's (W2FMI) design.
Custom K type permeability core is used to obtain the widest bandwidth.
1 Mhz to 50 MHz with lowest energy loss.
Typically insertion loss is less than 0.2 dB.
High Power Handling Capability - up to 10 Kw.
Highest voltage breakdown ratings.
Both "Current" and "Voltage" types available.
Aluminum case with SO239 connector and 2 ceramic feed through post as outputs. Custom case, fully encapsulation and other customization are available at added cost.
Dimension A : Height = 5.5" ( 6.8" including the flange). Width = 3.8". Thick or depth = 2.3".
Dimension B : Height = 5.8" ( 7.3" including the flange). Width = 4.8". Thick or depth = 3.6".
All units are weatherproof, built with non rusting materials.
