EW61 Elliptical Waveguide, is a Cablewave System product. Part # 810265-001.
Demensions? Have to see if I have a piece of it lying around in my tool
trailer. Here's a link to the manufacturer:
Look under Waveguide Products and Accessories.
Cablewave Systems is a division of Radio Frequency System also.
If you've never installed elliptical waveguide before, I might be able to
save you some heartaches. That stuff is easy to kink when bending it. Good
luck with your project.
