The perfect antenna set for LoRa/Helium users!

Everything you need is included - the antenna for Helium and LoRaWAN applications, a matching wall mount and the cable. Simply add one of each to your shopping cart and get started. This compilation is a suggestion based on our experience. At the same time, it is also one of the most frequently purchased antennas in this category. Of course you can also use other wall brackets and other cable lengths, below you will find suggestions for other suitable accessories.

The antenna

The antenna suggested here is a directional antenna. This means that all transmission energy is bundled in one direction and only signals from this direction are received. The so-called 3dB beam angle is approx. 60° in the horizontal plane. This does **not** mean that nothing is received at an angle greater than 60°, but only that at an angle of 30° the signal has dropped from the maximum in the centre to half (= 3 dB). Such a directional antenna is suitable for illuminating distant areas over a wide area.

Possible applications are

  • On a small mast at a height of approx. 6m, illuminating a part of a town from a distance of 100-300mm, the further away the larger the area and the weaker the field strength;
  • to illuminate a building from a distance of several dozen metres on a small mast, the lack of height is compensated for by tilting the antenna;
  • across a hollow or valley to a site on the opposite side of the slope. The distance also depends on the antenna on the opposite side, but distances up to 2-3km are quite possible.

This panel antenna is linearly polarised, by installation one decides the polarisation position: horizontal or vertical (usual is vertical). In contrast to circular polarisation (see bundle 2), linear polarisation has the advantage that there are no losses when the signal is in the same position. This is often the case when there are no obstacles between the antenna and the opposite side and the signal is most likely to arrive without reflections. reflections can cause a rotation of the polarisation. Such situations are mostly found in free locations without obstacles. And usually the gateways are more freely and directly audible than individual sensors in the field. This means that this antenna will probably pick up more gateways and other miners than individual sensors whose polarisation position is unknown or changing. The free and often elevated position of the gateways means that they are usually in direct view.

The wall mount

Here we have chosen a simple and light wall mount. It is not tiltable because a tilt bracket is included with the antenna. For mounting, you need 3 dowels and 3 screws each.

The cable

The suggested cable is a compromise between low attenuation and sufficient length. Of course, it makes sense to keep the cable as short as possible. Whether it makes sense to use thicker (less damping) cable depends on many details. For example, how to get the cable through the wall, how many adapters to use, etc. If in doubt, we will be happy to advise you.
