Sirio antenna is ideal for LoRaWAN and Helium miners with a maximum gain of 5.14 dBi and robust construction designed for wind resistance up to 150km / h.

For more than 40 years Sirio has been manufacturing antennas from its location near Milan. Antennas are produced and tested using the latest CNC machines, in accordance with the incompatible quality system ISO 9001: 2008.

To the right of the attachments you will find the Data Sheet

Supplied with pole mounting kit and all the necessary material, to assemble this antenna and place it on a mast in 10 minutes. This antenna is ideal for outdoor installation on a mast or convenient scaffolding or handrail section, but can also be easily screwed to a beam in your attic for indoor testing.

A female connector N is located at the bottom of the antenna, which is kept waterproof by an O-ring when assembling the antenna. We provide a variety of cables for connecting your antenna, see our cable section in Helium Accessories.
