Oscar 3A4G/5G LoRa 868-915 MHz High Gain Open Yagi Wall Mount Antenna

The Oscar 3A is an efficient, low-cost aluminium antenna with an enamel coating, designed with 9 elements to deliver a peak gain of 10.55 dBi.

It offers reliable coverage over the lower LTE and NR frequency bands, making it suitable for cellular applications in rural or challenging RF environments.

This antenna is also optimised for ISM applications within the 868-915 MHz range, achieving around 80% radiation efficiency and a gain of 9-10 dBi.

Equipped with an FME Male connector, the Oscar 3A ensures a secure connection when paired with the appropriate cable assembly, and it is recommended to seal the joint against water ingress.

A universal clamp is included for easy mounting on standard antenna poles, enhancing its practicality for various installation scenarios.
