Ext. Ka-Band 2-Port Feed Combiner Assembly

For Offset VSAT Antenna, f/d = 0.8

Model: DH-FEED-Ext.Ka-RXO-F/D=0.8

Product Overview

This external Ka-band dual-port feed combiner assembly is designed for offset parabolic VSAT antennas with an f/d ratio of 0.8. It enables simultaneous reception (Rx) over two ports while maintaining high isolation and polarization control — ideal for dual-LNB or diversity reception systems in satellite communications.

Technical Specifications

Applications

• Ka-band VSAT satellite communication systems

• Dual-LNB or diversity reception setups

• Offset parabolic reflectors (f/d = 0.8)

• Ground station, maritime, or mobile satellite terminals

Features & Benefits
