Accessories for Feeds

ACCESSORIES FOR FEEDS

The following components are available for use in assembling C-band antenna systems, or as spare parts. For other components such as filters, circular polarizers and OMTs, please refer to the Index.

SC-10AC Polarization Controller For ESR- or OSR-series antenna feeds. Provides remote selection of linear polarization. When used with feeds having remotely controlled circular polarization, can be employed to adjust feed polarization to vertical, horizontal, right-hand or left-hand circular. Operates from 115 VAC, 60 Hz, 12 watts.	PR-40 Polarization Rotator Interfaces with any standard Seavey Engineering scalar feed faceplate to provide remote linear polarization. Specify 3-wire servo or DC motor.
8300-14E WR-229 Waveguide Bend, E-Plane Die-cast low-cost waveguide bend with CPR-229F flanges, zero internal radius. Includes flange hardware and half-gaskets.	FP-40 Scalar Feed Faceplate 3.7 - 4.2 GHz for TVRO applications. Specify dash number for reflector F/D ratio. See pages 80, 81 - Note 4.
8300-14H WR-229 Waveguide Bend, H-Plane Swept waveguide bend with CPR-229G flanges, 3.0 inch internal radius. Includes flange hardware and gaskets.	8300-22 CPR-229 Flange Gasket Specify full or half thickness. Servo Motor 3-wire servo motor for ESR- and OSR-series feeds.
