Overview
The Skyware Global 1.8m Rx/Tx Extended Ku-Band SFL Class III Antenna is a rugged, commercial quality product suitable for the most demanding applications.
The reflector is constructed from glass fiber reinforced polyester [SMC] for strength and accuracy. A proprietary process developed by Skyware Global 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 (114mm) [4.50”] OD installation mounts.
All hardware is plated to 720 hour salt spray standards tested in accordance with ASTM B-117.
Cross-Polarization Isolation of 30dB on axis.
Excellent Tx Port-to-Port Isolation of 90dB or better.
Meets or exceeds regulator agency requirements.
Heavy-duty Class III mount for 11 kg (25 lb) RF electronics (LNB & BUC).
