Type 185: 1.8m Rx/Tx Standard Ku-Band SFL Class III Antenna with Mode Matched Feed

The Skyware Global 1.8m Rx/Tx Standard Ku-Band SFL Class III Antenna with Mode Matched Feed is a rugged, commercial quality product suitable for the most demanding applications. The Antenna features a unique feed which provides cross-pol performance that exceeds industry standards.

• The reflector is constructed from glass fiber reinforced polyester 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/El 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.

• TX Cross-Polarization Isolation of 29dB within 1dB contour.

• 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) with
