This PCB Set are supplied without copper tubing, we will add this variation soon for all types. Currently only the BN43-7051 variation is available with copper tubing.

The 2 PCBs are designed so to hold a dual apperture ferrite core, and together with 2 copper sleeves or coax-cable's braid to form the center-tapped one turn ususally required for an impedance transformer.

Any type of dual apperture cores can be used, for example 2 or three placed in series, or even made by individual small or large toroidal beads or rings.

As shipped, a small cut is required from the buyer to separate the 2 PCBs

A footprint for a neutralizing capacitor is also added so it can be used if needed
