The Delta 25 is a compact, right angled direct connect 2.4 GHz stubby antenna.
Typical applications are Point-of-Sale terminals and networked IoT modules.
The antenna can be used with most modern-day Wi-Fi modems such as NetGear and TP-link that operate on the traditional 2.4 GHz frequency.
The Delta 15 is available with the SMA male and the reverse polarity (RP) SMA male connectors.
