1:1 FCP Isolation Transformer 2kW #1142s
|Manufacturer: Balun Designs|
This is a unique 1:1 transmission line transformer intended to provide highest possible isolation between input and output. Consequently there is no direct electrical connection between the input and output with all RF energy being conducted through the massive iron powder core. This makes the FCP antenna very quiet while also providing the required inductance for matching to the folded counterpoise.
Specifications meet the K2AV FCP Isolation Transformer requirements for use with his Folded Counterpoise for 160 or 80 meters.
