TRIBAND

This feed family includes prime focus dual-band feeds operating in S/C-bands and S/Ku-bands as well as Tri-Band feeds operating in all three frequency ranges.

Tri-band feeds are a unique product of Seavey Engineering. They provide complete access to S-, C- and Ku-band communications satellites.

Several models having various polarization choices are offered. They range from two-port devices to five-port versions with all polarization possibilities. They find applications in Earth Stations used with ARABSAT and INSAT, INTELSAT and DOMSAT systems.

All of these feed systems feature high quality, sealed construction. Phase centers for all frequency bands are coincident. They are optimized for F/D ratios from 0.35 to 0.42. All S-band RF ports are Type N jack connectors. All C-band RF ports are CPR-229G and all Ku-band RF ports are WR-75 waveguide flanges. The following frequency bands are standard:

Model ESA-20-124HCR is a tri-band (S/C/Ku) feed. It is linear polarized in S-band. There is one C-band linear polarized RF port and one linear Ku-band port. The polarizations of the C-band and Ku-band port are remotely changed using a standard, patented probe servo motor. It accesses the ARABSAT, DOMSAT and any Ku-band satellite. Overall length is 14.5 inches. Diameter is 8.75 inches and weight is 6 pounds. It is optimized for F/D ratios of 0.35 to 0.42

Model ESA-20-44C-1212 is a tri-band (S/C/Ku) feed. It is linear polarized in S-band. There are two C-band circular polarized RF ports and two linear Ku-band ports. It accesses the ARABSAT, INTELSAT and any Ku-band satellite. Overall length is 24.0 inches. Diameter is 8.75 inches and weight is 12 pounds. It is optimized for F/D ratios of 0.35 to 0.42.
