  • CONNECT SPU TO ODU Stop panning at the point of maximum signal strength (highest AGC voltage) and PROTEUS AMT M-SERIES The SPU-to-ODU cable is a single 50-ohm RG-8A/U TNC to Type N coaxial cable. tighten azimuth adjustment nuts. RADIO Cable length limit is 22 dB loss at 350-MHz (about 300 meters). Remember to add 4.
