868 MHz 4.4dBi tuned HNT antenna for Helium LoRa Hotspot

rating No review at the moment

This antenna is specially designed to improve the performance of Helium Network (HNT) hotspots and miners, whether for use in urban areas with dense hotspot coverage, or in suburb areas.

It is tuned for 868 MHz frequencies, with a SWR of less than 1.2, which allows it to use almost the entire transmitted power, with a real gain of 4.4dBi (2.25dB), while non-tuned wideband antennas will lose a more or less important part of the transmitted power, due to a too high SWR.

The polarization of the antenna is vertical and the radiation omnidirectional, the connector is N female (take a cable or an adapter with N male connector to be compatible).

The mounting with the mast support integrated in the antenna and the supplied brackets, also facilitates the mounting and stability of the HNT V2 antenna on a mast to be used with a diameter of 35-70mm.

Supplied with: 1 HNT Helium V2 868 MHz OPA Design antenna, with mounting bracket supplied.

Optional: Add SAW 868 MHz bandpass filter, to suppress out of band emissions and increase the number of witnesses if you are in a "noisy" environment and depending on the coverage in your area.
