10. Cable guidelines
The antenna can be connected to the ThurayaIP terminal with different types and different
lengths of coaxial cable. However, the insertion loss of the cable is critical to the correct
function of the antenna, as the transmitted power from the antenna may not be too low nor
too high. The following cables have been carefully selected to take this into consideration. The
lengths of cable shown are therefore not maximum lengths only, but also minimum lengths.
The RF insertion loss at 1600 MHz needs to be 5 dB.
The user may not alter the lengths of the cables. If a different length is needed for practical
reasons, please change the cable type to the type suitable for that particular length.
Cable length Cable type Cable diameter Cable weight
Meters (Feet) Mm (inches) Kg (lbs)
6m (20 ft) RG58C/U 5.0 (0.20”) 0.25 kg (0.5 lbs)
10m (33 ft) RF195 5.0 (0.20”) 0.37 kg (0.8 lbs)
15m (50 ft) RF240 6.1 (0.24”) 0.75 kg (1.5 lbs)
30m (100 ft) RF400 10.2 (0.40”) 3.0 kg (6.6 lbs)
The default cable is the 6m RG58. This cable is fitted with the necessary connectors for correct
operation, SMB (female) for ThurayaIP and QMA (male) for the antenna.
For the cables with larger diameter, it is not always possible to fit the small connectors. In
these cases, small adaptor cables will be included.
The information above relates to the SAT cable between the ThurayaIP and the antenna.
However, the corresponding GPS cable will be of the same type and length.
For ordering information regarding cable sets, please consult the separate ordering information
document.
