2.4 & 3.0 Meter Receive-Only Antenna Systems
Published 2.4 m and 3.0 m receive-only configurations include model-specific C- and Ku-band performance, mounting and environmental data. Send the required band, feed, site and pointing information for review.
Match the Aperture to the Receive Requirement
Typical use is fixed satellite receive for broadcast, telecommunications and data reception. The pedestals are designed for orbital arc coverage and can be adapted to ground or rooftop installations.

Mount configuration is model-specific. The 2.4 m sheet lists a turning-head pedestal with an elevation-over-azimuth axis; the 3.0 m sheet lists an elevation-over-azimuth tripod, hot-dipped galvanized after fabrication.
Both model sheets list survival wind as 125 mph (200 km/h). Any 180 mph high-wind configuration must be confirmed for the selected model and site in the quotation.

Feed Configuration Is Part of the Antenna Order
The C/Ku receive tables use WR-229 CPR and WR-75 CPR interfaces. L-band, X-band, multi-feed or other project-specific receive paths should be confirmed with the antenna rather than assumed from the C/Ku table.
Dolph’s custom antenna feed systems cover feed horns, OMTs, filters, diplexers, polarizers and rotary joints. For complete assemblies, see the antenna feeder networks.
For multi-band planning, read how to integrate multiple frequency bands in an antenna feed network. For installation work, see how to connect a waveguide feed to a dish antenna.
Check Feed CompatibilityManufacturing, Measurement and Warranty Information
