Helium Outdoor Antennas FAQ Installation & Deployment

Helium Outdoor Antennas FAQ

  1. What is an omni-directional antenna?
    • a omni-directional antenna is an antenna that radiates in every direction.
  2. What characteristics does a good helium omni antenna need?
    • A good outdoor helium omni antenna needs to combine effective RF performance with excellent build quality. Reliable gain figures are important for planning your deployment and the use of quality materials such as fibreglass tubes to ensure longevity when exposed long term to UV from sunlight and the weather.
  3. What mounting options are possible?
    • A good helium antenna will offer multiple mounting possibilities. Limiting the mounting to only pole mount or only wall-mount is restrictive therefore an antenna that offers both mounting options is preferred.
  4. Is the choice of RF cable important for Helium deployments?
    • The selection of quality RF cable is important for Helium antenna deployments especially for longer cable runs where it is critical to minimize signal losses (attenuation) over the length of the cable. For 10M or 20M cables, look towards 240 or 400 type cables respectively to mitigate signal losses.
  5. Is a surge arrestor required for Helium installs?
    • This is really a question for the installer. In the UK lightning strikes are very rare, so typically surge protectors are not used as the chance of a strike is so low. However, a “belt-and-braces” approach might be considered where a surge protector is used.
  6. What the best advice for choosing a Helium outdoor antenna?
    • Use a quality antenna from a reputable manufacturer where you can be sure that the specifications published match the performance of the antenna. Ensuring that the antenna is made of quality materials means that the antenna is unlikely to fail with a few weeks of installation. Select high quality low loss cables that mean you do not lose all the gain offered by the antenna over the cable run.

Helium outdoor antennas

Helium outdoor antennas things to check before you buy

The Helium network offering low power coverage across the world is rapidly growing in popularity. Across the world, as Helium miners are being deployed, people are looking at outdoor omni-directional antennas to optimise coverage from each miner installed.

This brief comment is going to focus on build quality.

There are quite a few outdoor antennas on the market, but selecting one with build quality good enough to be permanently installed outdoors without falling apart is critical.

Many low (and very low) cost antennas are available from online market places. Ignoring poor RF performance for now, many of these low cost antennas suffer from poor build quality or inferior materials and are unlikely to survive one average winter outdoors.

Our suggestion is to look for European-manufactured Helium outdoor antennas that tend to focus on quality materials and not solely on price. One particular area to focus on is the sheath or tube as poor materials weather and crack very rapidly leading to unit failure. A proven, durable option is an antenna with a fibreglass tube which will withstand many winter’s deployment without suffering weather or UV-degradation.

Also check the brackets/clamps that come with antenna. Are they fit for purpose? Is the antenna secure enough when mounted?

There is nothing worse than having to replace the antenna you took the trouble to install three months ago due poor survivability of the materials.

Just in case you’re interested, here is a link where you can purchase quality fibreglass tube 868 MHz antennas.
