The STR-1000 has several different lengths of wire antenna which are laid out behind the user
and allowed to lay on the ground as the user moves in the underground or surface environment.
The low drag of the wire will prevent the antenna from getting snagged on rocks or other
protrusions when in use.
The STR-1000 can also use one of the very short stainless whip antennas. These should only be
used in a fixed, non mobile, location. In addition, telescoping short antennas are provided which
should also only be used in fixed locations.
Recommendations for which wire antenna will give the best results for a
frequency/depth/distance on the surface combination, are given in Tables 1 and 2.
Table 1. STR-1000 Antenna Selection for Frequency (1st to 3rd choice)
Recommendation.
Table 2. STR-1000 Depth vs. Surface Distance Recommendation (* = only in
optimal conditions).
Note:
Lower frequencies and longer antenna lengths will give the best depth penetration
at all distances.
