CPI SAT 4.8M Intelsat Type Approved Compact Cassegrain Antenna
C, Ku, X and Ka-Band configurations available, Tx/Rx or RX only
4.8 Meter Tx/Rx Cassegrain
The CPI SAT (formerly GD Satcom Technologies & Prodelin) 4.8M antenna delivers extraordinary uplink performance at a cost effective price. This 4.8 meter antenna is an ideal solution for uplink applications that require Intelsat, Eutelsat, Asiasat or Hispasat type approval. The CPI 4.8M antenna is available in a wide variety of configurations from transmit/receive, receive only, C-Band, Ku-Band and high frequency Ka-band.
Precision Construction
The CPI 4.8 Meter antenna offers precision-formed panels, contoured radials and a machined hub assembly. It also features an innovative feed and subreflector design which results in high gain, low noise temperature, high antenna efficiency and excellent rejection of noise and microwave interference. The reflector is supported by a galvanized pedestal that provides the required stiffness for pointing and tracking accuracy. The pedestals are designed for full orbital arc coverage and are readily adaptable to ground or rooftop installations. All configurations meet CPI SAT's own type approved quality assurance and performance guarantee.
