13cm single cavity

The goal is to find a commonly avaible item that can be easilly tunned to the 13cm band.


Diameter of the cavity (mm) vs resonant frequency, without parasitif element.

The parasitic element (screw) is able to shift down the resonant frequency.

The real thing

  • 42mm copper pipe
  • 7mm feed probe
  • SMA connector + RG402
