Balanced Line Isolator.

Balanced Line Isolator. 

Also balanced lines benefit from insertion of an Common-Mode Choke type line isolator.

When installed in a ladderline, this choke will remove, over a broad frequency range, any common-mode current, without affecting the differential mode signal current, thus minimizing radiation from the feedline and optimizing antenna radiation pattern.

This product is a special variant of the standard 1/1 Common-Mode Choke, utilizing a symmetric transmission line pair that is designed for maximal inter-winding breakdown voltage.

To achieve this goal, the teflon insulated wires are additionally slipped into teflon sleeves having a dielectric breakdown rating of 24 kV/mm.

This is needed as the CMC is deployed in a random impedance environment. 

Standard this type of line isolator is provided with wire connection terminals at the input and output side.

Max Power: 1000 W PeP (ICAS).

Constructed to the high quality standard of ON7FU products.

NEW !  Updated version with wire connection terminals on sides of enclosure, in order to increase creepage distance an thus provide additional insulation for abnormal high voltages (e.g. surges due to
