Comparison Oregon RAR502X vs Oregon RAR502

The maximum distance to the main unit of the weather station where an external sensor can be placed. For wired versions (see "Type of external sensor") this indicator corresponds to the length of the standard cable; for wireless, a guaranteed radio communication range is usually indicated within the visibility limit, provided there is no interference or foreign objects in the signal path. Anyway, it should be taken into account that the maximum installation range is usually less than the claimed range in fact. This is due to the fact that the wire can rarely be laid in a straight line, and the radio signal, in turn, is affected by obstacles and electromagnetic interference. Therefore, it is worth choosing a weather station for this parameter with a certain margin.
