offset thermoset-molded reflector.
• Single bolt fine elevation adjustment.
• Extruded aluminum feed support arm.
• Pre-assembled Az/El/Skew
mount for optimum alignment
capability.
• Plated hardware for maximum
corrosion resistance.
• Includes Rx/Tx feed assembly.
• Available with Co-Pol or CrossPol feed.
• All materials comply with EU
Directive No.
2011/65/EC (RoHS).
• Designed for typical 1W and
2W Ku-band Block-Up Converters (BUCs)*
* 2 kg or 4.5 lb or max. weight for RF electronics (BUC and LNB)
The Skyware Global 75cm Rx/Tx Ku-Band Elliptical 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 sustains the parabolic shape necessary for
transmit performance.
• The heavy-gauge galvanized steel Az/El/Skew mount provides rigid sup-
port to the reflector.
• The mount secures the antenna to any 60 mm (2.38”) O.D. mast and
prevents slippage in high winds.
• This mount allows for precise alignment of the elliptical reflector to the
geostationary arc.
• A special powder paint process offers excellent protection from weather-
related corrosion.
