Overview

New Skyware Global 69cm Rx/Tx Extended Ka Band Antenna is a rugged, commercial quality product suitable for the most demanding applications.

The reflector is constructed from pressed steel for strength and accuracy. A proprietary process developed by Skyware Global ensures high RF reflectivity from powder coated galvanized steel.

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 2” or 2 3/8” OD installation mounts.

All hardware is plated to 720 hour salt spray standards tested in accordance with ASTM B-117.

Tx Cross-Polarization Isolation of 25dB (within 1dB b/w) or better for CP Application.

Excellent Tx Port to Port Isolation of 90dB or better.

Meets or exceeds regulatory agency requirements .

System designed for typical Ka-Band RF Electronics.
