Global Skyware Ku Band Receiver Transmitter (Rx/Tx) Offset Antenna System

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

The reflector is thermoset-molded for strength and surface accuracy. Molded into the rear of the reflector is a network of support ribs which strengthens the antenna and helps to sustain the necessary parabolic
shape. The reflector optics feature a long focal length for excellent cross-pol performance. The heavy gauge steel Az/El mount secures the antenna to any 73-76 mm (2.88”-3.00”) mast and prevents slippage in high winds. A special powder paint process offers excellent protection from weather-related corrosion.

Features:

• All materials comply with EU directive No. 2011/65/EC (RoHS).
• Long focal length optics for low cross-pol performance.
• Fine azimuth and elevation adjustments.
• Available with Ku-band co–pol or cross–pol feeds.
• Galvanized 19 mm (.75”) O.D. side feed support legs and 51 mm (2”) O.D. lower feed support.
• Plated hardware for maximum corrosion resistance.
• Class II system designed for typical 2 W and 4 W Ku-band Block Up-Converters (BUCs).
• Type approved for use on Intelsat and Eutelsat satellite systems.
