1.2m Ku Band Receiver Transmitter (Rx/Tx) Antenna System

The 1.2m Class I RxTx Antenna is a rugged commercial grade product suitable for the most demanding applications.

The reflector is constructed from glass fiber reinforced polyester [SMC] for strength and accuracy. A proprietary process ensures high RF reflectivity as needed for Ku-Band operation.

The precision Az/EI mount is made of galvanized steel for excellent corrosion resistance. This mount includes special features to increase pointing accuracy with low backlash and lockdown error.

This Az/EI allows the antenna to be installed on standard 73-76mm [27/8”- 3”] OD installation mounts. All hardware is plated to 720 hour salt spray standards under ASTM B-117.

Features:

• Cross-Polarization Isolation of 30dB on axis
• Excellent Tx Port-to-Port Isolation of 90dB or better
• Meets or exceeds regulator agency requirements
• Class I system designed for typical lightweight Ku-band RF Electronics
• ISO 9001:2008 Certificate of Registration
• All materials comply with EU directive No. 2011/95/EC (RoHS)
• Precision Az/EI Mount
• Fine Azimuth and Elevation Adjustment Features
• Standard Waveguide Flange
