Here are my test results for a B&W 6 position switchbox as measured on a
HP8753D network analyzer. I don't remember the model number but it is the
one in the rectangular box. The actual switch component is a ceramic wafer
switch. The UHF connectors are very well made and look like they can take
a lot of abuse.
