ABSTRACT:
A probe for use in a coax-to-waveguide transition is uniformly coated with a dielectric material by inserting the probe through an elastic membrane covering a container of uncured RTV elastomer to thereby dip the probe. The membrane wipes excess elastomer from the probe during withdrawal, and seals the RTV from ambient air to thereby prevent its premature curing in the container. If moved sideways before withdrawal, the coating thickness can be made to favor one side over another. A magnetic block is fitted into a waveguide. A slot in the magnetic block is also filled with uncured RTV elastomer. The probe is inserted into the slot, embedding it in the uncured RTV. Upon curing, the probe is protected from high voltage arcing to the waveguide. A cured RTV elastomer washer is preassembled to the probe before dipping, to precisely fill the void between the connector base and the magnetic block with a like material.
