The LevelOne WAN-7151 is a directional, dual-polarization antenna that can be mounted either indoors or outside. Dual-polarization offers the flexibility of two different communication channels receiving simultaneously, while a high gain of 15dBi offers better range and signal strength. If mounted outdoors the weatherproof housing can withstand temperatures from minus 30°C up to 60°C, as well as rain, sNAw, dust and other harsh conditions.
