Introduction

Often feed requirements involve unique requirements. Typical examples are lightweight, high shock and vibration feed components for aircraft and space systems, high power components for radar and GOES or transmit/receive feeds for US and Intelsat satellite dish antennas. Manufacturing techniques employed are aimed at achieving desired technical results and cost objectives. For example, receive only dual polarized feeds and multi-satellite feeds are highly tooled aluminum castings. Electroforming methods are used to generate complex internal contours, high strength and light weight products. Such techniques are common for orthomode polarizers and Tallguide , an ultra low loss waveguide for satellite earth station uplinks and radar. AFC's conical horn antenna product line contains a complete list of Western Electric equivalent feed component networks.

The table page below lists AFC's most common feeds for satellite communications. Please contact AFC's sales department sales@afcsat.com for your specific requirement.
