EW-61 refers to ellyptical waveguide, but is not current production, at
least not in our catalogs and we are an Andrew dealer.
If it exists, it must be between EW-52 and EW-63. The characteristics of
52 and 63 are:
EW-52 4.6-6.4 GHz. Size: 1.31" X 2.25" overall
EW-63 5.85-7.1 GHz. Size: 1.16" X 2.0" overall
Waveguide is VERY low loss, compared to coax, at it's design frequency.
Components, however, are very pricey.
