Line Isolators are 1/1 UNUN Common-Mode Chokes.
They can be installed at any location in the coaxial cable to reduce common-mode currents on the outer braid.
In this way they prevent interference in transceiver and ancillary equipment during transmission, as well as man-made noise during reception.
Standard Line Isolator.
The most standard isolator is constructed using a 61 mm diameter material type #43 ferrite torroid.
This version is useable between 1.5 to 55 MHz, and has it’s maximum impedance value in the middle of the HF frequency range.
It is the most universally deployable Common Mode Choke type Isolator.
LOW HF Line Isolator.
The LOW HF isolator is constructed using a 61 mm diameter material type #31 ferrite torroid.
This version is useable between 1.5 to 55 MHz, but has it’s maximum impedance value on the low side of the HF frequency range.
It is typically advised when optimum common mode rejection is wanted on the Low Bands.
