(Options)
Model:
V740-A01-3.0M
Model:
V740-A01-10M
Length:
3.0m
(9.8’)
Length:
10m
(32.8')
Insertion Loss: 1.5 dB min.
Insertion Loss: 1.5 dB min.
Cable Type:
3D-2V
Cable Type:
5D-SFA
Connector:
Reverse TNC to Type N
Connector:
Reverse TNC to Type N
Cable Diameter:5.5mm (0.22’’)
Cable Diameter:7.6mm (0.30’’)
Super Long cable
(Options)
Model: V740-A01-20M
Length:
20m (65.6’)
Insertion Loss: 3.0 dB min.
Cable Type:
5D-SFA
Connector:
Reverse TNC to Type N
Cable Diameter: 7.6mm (0.30’’)
Note: Because the Super Long cable produces more insertion loss than the Long and short cables, it
decreases communication distance between a reader and tags by approx. 20%.
