Hi- Anybody know of a source or contacts that could lead to a used or surplus coaxial adaptor and waveguide for WR-770 or WR-975 waveguide? (Also called WR-1000, WR770, WR975, WR1000). I've searched considerably on the internet to no avail (unless I agree to purchase a really expensive new part that will be used very little).
I need to setup a system using a short piece (approx 3ft overall length) of waveguide with coaxial feed arrangement for testing some isotropic probes. The open-ended waveguide- when compared with conventional antennas- enables much better analysis and definition of the waves from the open end, better far field conditions, etc.
I'm also considering fabricating the waveguide from sheetmetal with a side probe, I've seen the related post on this forum from somebody looking at a similar arrangement. I'd prefer to simply purchase a relatively inexpensive piece of waveguide with a coaxial adaptor (either end feed or side feed) and get this done...
Thanks in advance!
