DELTA7A/X/SMAM/S/S/11

Delta 7A DUAL BAND WIFI / 5G / 4G / Bluetooth / Zigbee / ISM 2.4G & 5.8G HINGED ANTENNA Key Features • Supports 5G NR / 4G LTE • Supports Dual-Band WiFi full 2.4 GHz & 5 GHz spectrum • Supports Bluetooth and BLE, Zigbee, ISM 2.4 GHz, ISM 5.8 GHz & IEEE 802.15.4 bands • Hinged Mount • Omni-Directional General Description Additional Considerations The Delta 7A is primarily designed as a dual band WiFi antenna, tuned to the 2.4 GHz and 5 GHz bands. It also supports some of the 5G NR and 4G LTE Cellular bands. The hinged joint provides a flexible means of setting the antenna into the optimum position for WiFi transmission. • Adjustable mounting allows positioning for signal optimization • Dual band flexibility – choose least congested network • Meets all EU compliance criteria for electronic goods The Delta 7A supports WiFi, Bluetooth, Zigbee and ISM based applications and can be used with most modern-day WiFi modems that operate on the traditional 2.4 GHz and extended 5 GHz bands. The table for 4G and 5G bands lists the supported frequency bands for LTE. The Delta 7A is supplied, as standard, with either an SMA male or a reverse polarity SMA male connector.
