Dummy Loads and Waveguide Switches for sale. We have the following 3 of those C band loads, two of them have the transition waveguide that goes to the smaller size (I think for whatever the normal C band TX waveguide is). Also have 1 of the 1000 watt WR75 Ku load and 4 switches. The switches are 24VDC. Also have a Ku band Apollo VPC box and a similar sized C band load with crossguide coupler if you’re also interested in those.
