Type 245: 2.4m Rx/Tx Standard Ku-Band SFL Class III Antenna with Mode Matched Feed

The Skyware Global 2.4m 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 insures 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 168mm [6.63”] OD installation mounts.

• All hardware is plated to 720 hour salt spray standards under ASTM B-117.

• Tx Cross-Polarization Isolation of greater than 31dB 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) and ≤ 16W installed power. (BUC support kit may be required depending on application)
