SLA 71
Application area
The SLA 71 is a read/write antenna in the middle of the performance range.
It permits greater distances to the evaluation unit (ASM).
The length of the line between antenna and evaluation unit is 55 m (max.).
The SLA 71 can be operated on the following interfaces: ASM 724 and
ASM 754.
