AlfaSector for Helium US
Net price: $79.00
, SKU: AS915
AlfaSector US for Helium operates at 915MHz with 8.5dBi gain. The outdoor sector antenna is dedicated to Helium Network devices like SenseCAP M1 and other IoT Gateways. Comparing to omnidirectional antenna, sector antenna transmits signal to a farther distance because of the antenna’s directional gain.
High gain sector antenna guarantees larger coverage. As a result, your Gateway is connected to the higher number of devices in Helium network, increasing HNT profit.
Advanced mounting system gives significant advantage that it can be adjusted in the range of +/-35 degrees in two planes, also in case of wall mounting.
Supported systems: US915, AU915, AS923, KR920
