¶ General Description
The Delta 7A is a lightweight direct-connect antenna developed primarily for dual-band Wi-Fi, short-range wireless and industrial IoT equipment, with additional support for selected cellular bands. Its slim 108 mm profile and hinged joint allow the antenna to be positioned for optimum signal transmission, while the cable-free design simplifies installation.
Strong operation across 2300–2690 MHz supports selected 3G UMTS, 4G LTE, LTE-M, NB-IoT and 5G NR bands. Coverage from 2400–2500 MHz enables Wi-Fi, Bluetooth, BLE, IEEE 802.15.4 and ISM applications, while dependable performance across 5150–5990 MHz supports 5 GHz Wi-Fi and 5.8 GHz ISM operation. The antenna provides 0–3 dBi gain and 64% radiation efficiency.
A durable TPEE housing, low 10 g weight and omnidirectional radiation pattern make the antenna suitable for space-conscious equipment requiring dependable wireless connectivity. SMA male and reverse-polarity SMA male options enable direct connection to a wide range of compatible devices. Alternative connector types can be supplied for high-volume orders.
