The distance of 500m is a theoretical data, it shall be operated in an open ground, no barriers, no any interference. But in the practice, it will be hindered by trees, walls or other constructions, and will be exposed to some interference by other signals. Therefore, the actual distance may or may not reach 500m.
If you stretches the telescopic antenna, it can have a further working range, which is twice as much as it used to be.
Modulation Mode: ASK
Operating Temperature: -20 ° C to +70 ° C
Unit Size: 85mm x 36mm x 16mm
