Description
We offer a standard range of Waveguide to Coaxial Adaptors.
The Economy range of adaptors are offered for most everyday usage. Using Low Power connectors the Economy version offers a good compromise between performance and cost. To maintain the lowest prices, the economy version is offered in aluminium. Painting, plating and brass versions are available at extra cost. It is possible to offer improved performance specifications for narrow band options.
Precision Adaptors are offered to suit laboratory or test bench applications. The precision version is manufactured from brass and painted with attractive, hard wearing, epoxy paint finish as standard. Each adaptor is tuned to offer the highest possible performance over the full waveguide frequency band (Improved performance over a narrower bandwidth is available).
