How To Choose The Right Helium Antenna?
When you own a Helium Miner, you want to get maximum results. The most important part of your setup, is your Antenna. There are multiple things to take in consideration, when you choose a antenna.
If you just want to know which Antenna to buy you can choose one of the 3 antennas above!
For Helium Hotspot owners who really want to maximize there profits and understand how the Helium Antenna works, we have gathered the best information.
Down below you will find the three most important factors to consider when choosing the right Helium Miner Antenna for your setup.
Everything about Omni Directional and Directional Antenna’s, and which is the better choice.
Should you use a high-gain or a low-gain Helium Antenna, and what about EU Regulations?

Helium Antenna Direction: The Differences Between Antennas.
The first thing you want to know when choosing the right Helium Antenna, is what type of antenna you need.
We can choose between an Omni Directional Antenna, and a Directional Antenna. Below you find both of them explained.
A directional antenna can only send the signal in one focussed direction. This means you might miss a lot of signals and could reach less other Hotspots.
Omni Directional antenna
An Omni Directional Antenna will send signals in all (omni) directions. This means the antenna will direct the signal a full 360°
In most cases, the best choice is to use an Omni Directional Antenna for your Helium Hotspot. With the Omni Directional Antenna you can reach all the hotspots in your surroundings. But, there are some cases where a Directional Antenna is the better choice.
For example, when the Antenna is placed at the edge of a mountain, you simply can’t send any signals through the mountain. The signal just isn’t strong enough to reach the other side. In this case it would be the better option to focus your signal strenght the other way, away from the mountain, with an directional antenna.
Helium Antenna Gain: How Does Gain (dBi) Work?
The second thing you need to consider when choosing a Helium Miner Antenna, is the Antenna Gain.
The Antenna Gain is mostly described as the dBi of the antenna. Every single decrease in the dBi, makes a big difference in the strength of the Helium Antenna. Likewise, when the dBi increases, the signal strength will also increase rapidly.
But the dBi of the Antenna also has a huge effect on where the signal is being send. Importantly, no Antenna can create more signal strength, it can just focus the signal in a certain direction.
4 dBi Antenna
6 dBi Antenna
8 dBi Antenna
To clarify with an example, above you can see how the radiation pattern changes when the dBi increases. When the dBi of your antenna is low, the horizontal reach of your antenna will also be low. The antenna will cover a more vertical area (up and down), like in the first image.
Secondly, the antenna with a higher dBi will have its power focussed to cover a more horizontal area and will reach hotspots much further away. However, it will also cover less vertical area.
Higher Gain: Does It Work?
Some people argue that a higher dBi antenna will not reach near Hotspots in your surroundings, because the radiation pattern is too narrow and will send the signal over the Hotspots, like in the image on the right.
In reality, altough the signal is more narrow, an Helium Antenna with a higher dBi has side lobes, these are small antenna’s that reach the areas that the main signal can’t reach, like in the picture on the left side.
However, these side lobes are not as powerful as the vertical signal from a low dBi Antenna.
Does High dBi work with EU Radiation Regulations?
So the question is: Why should I get a high dBi antenna, when the signal is reduced to fit radiation regulations?
The answer is very simple, with your output of 16,5 dBi and the more focussed antenna you can reach much more Hotspots. But, when your transmitted signal reaches more than 14 Hotspots, the network will select only 14 to communicate with.
So, for what do you need a higher dBi Helium Antenna? Most money earned with a Helium Miner, comes from witnessing other Hotspots. (Average 80%)
When you get a high dBi antenna, you can also witness more Hotspots. This is because your receiving signal will also be focussed.
When you can receive more signals from other Hotspots, your Helium Miner will be chosen as Witness much more and your rewards will go up!
Helium Miner Antenna Placement
Most importantly, Antenna placement. The location of your Helium Antenna might be the most important aspect, because the location dicates which type and gain antenna is best for your situation.
Helium Antenna Location (Geographics)
Antenna location has everything to do with the landscape around the Antenna. A mountain can definitely block your signal, but also for example trees can reduce the strength if you are living in a place where there are many trees. Likewise, when your antenna is placed near water, the signal can travel much further.
Indoor Or Outdoor Placement
When you want to get the most out of your Helium Hotspot setup you need to place your Helium antenna outside. The difference in your earnings between indoor and outdoor placement can be very high. This is because a wall of 20cm / ~8″ thick will reduce the signal by 27 dBi.
Helium Antenna Height
One of the most important factors for a Helium Miner is the placement height of the Antenna. For example, when you place the antenna on for example 3 meters the signals will be blocked by the ground (earth) by lots of buildings, trees and other the surroundings. When you place your antenna on 9 meters the signal will bounce against fewer objects and will reach much further.
The Best Helium Miner Antenna: Conclusion
Finally, the conclusion. In most cases, a high dBi (8-10) Omni Directional Antenna is the best choice.
However, every setup is unique and to optimize your earnings, you need to make the right choice for your location.
