In figure 1, below, pictures of the HDR-160MHz are shown. All antennas in this series 
have the same basic layout, only that for the 750MHz, no-side handles are available. 
In the following a brief description of the unit is given, with reference to arrows and 
labels in figure  

1.  GPS. The black plastic on top of the connector tower hoses the in-build 

differential GPS-receiver and antenna. This receiver has in-built SBAS-
correction capabilities. It is essential that the antenna is mounted in a such a 
way to give the GPS antenna as much of free sky as possible 

2.  Battery. The LI-Ion batteries are housed in a casing of worked aluminum, and 

have a nominal capacity of 7.8 Ah, 11.1V. This gives at least 5 hours of 
operation, somewhat varying between the different models. 

3.  Battery release knob. The batteries are held in place by a spring loaded pin, in 

order to release/mount the battery, the knob is pulled. 

4.  Measuring wheel mount. The measuring wheel is mounted via a protected, 

waterproof 9-oin d-sub connector. The wheel is locked in place by a vertical 
pin, see later section. 

5.  Mounting inserts. The units have 2 inserts, M6-threads, on each side, these 

are intended for mounting purposes, either mounting the antenna in a custom-
designed carrier or for carrying purposes. 

6.  Carrying handles. By default the 3 lower frequencies have handles mounted 

on the perimeter of the units. These are intended for tunnel wall, rock-wall 
applications as well as for pure transportation handles. 

7.  Product label and LED-indicators see later sections. 
8.  Connection tower. Power, communications as well as on/off button is mounted 

in a casing of worked aluminum on top of the unit; this casing also contains the 
GPS unit and antenna, if this option is installed. Note the connection tower is 
not intended to be removed at any time, waterproofness of the unit cannot be 
warranted if this part is removed. 

9.  Inserts for wear-plate. Two inserts, back and front, are intended for fastening 

of wear plates, M4-threads. 

10. Mounting inserts. Additional inserts, M6-threads, are mounted on  the top 

metal plate, by means of insert-rivets.

arrows and labels refer to items explained in the text above.
