Radio Range to Diver-DXT

Radio Range is 500 m (LOS). This is under good conditions!!!

Radio Range is negative affected by: Obstacles which interfere Line Of Sight (LOS). Obstacles can be

anything like vegetation (plants/trees), buildings, cars etc. Metal close to the Diver-DXT or Diver-Gate antenna. Examples

are metal well cover, car/truck etc. Position of antennas (the higher the better). Examples are

Diver-DXT under ground level or on ground level. Weather conditions (fog, rain, snow etc). Flooding conditions. Diver-DXT under water (or snow/ice)

Radio Range to Diver-DXT

Street cover: Diver-DXT is underground level. Radio distance LOS 100 m. Radio distance around corner 20 m.

Metal casing: Diver-DXT is 1 mabove ground level. Radio distance LOS 200 m.

Plastic casing: Diver-DXT is 1 mabove ground level but withvegetation. Radio distance LOS 200 m.
