CPI SAT Series 1184 1.8m Ku-Band Tx/Rx VSAT Antenna
1.8m, Receive and Transmit, cost effective and reliable
C-Band 1184 Ku-Band Tx/Rx VSAT
The CPI SAT (formerly GD Satcom Technologies and Prodelin) 1184 series 1.8M is a rugged, reliable antenna system, which will operate with high efficiency and at the same time successfully withstand the effects of the environment. The basic 1.8 meter antenna consists of an offset reflector, reflector support, feed support structure and Az/El positioner. The 1184 1.8m antenna is ideal for fixed VSAT applications.
