“SIG (sIRG) & GVF – What a Ride!” Martin Coleman

Starting in 1995, Dave (‘Whirlwind’) Hartshorn and I (working out of Singapore for SSE & Prodelin, respectively) witnessed, first-hand, the “explosion” of TDMA-Voice VSAT networks here in South East Asia. 1.8m antennas (C-Band, Linear-Polarised) were being frantically installed in (then) very remote locations. The installers lacked training in the pitfalls associated with Cross-Pol, Pointing, Over-drive, and IFL cabling/connector issues.
