Hey guys i’m laura with Rokland Technologies your leading sources on helium mining antennas and accessories. Today we’re going to be showing you the top five do’s and don’ts of helium mining and bonus we’re having a major giveaway announcement at the end of this video so make sure to watch all the way through for your chance at a free SyncroB.it helium miner! That’s right we’re giving away a free helium miner so make sure to watch all the way through to the end of the video One of the best choices you can make is getting an appropriate antenna for your location so whether you’re in the city, the suburbs, or out in a rural environment you’re going to want to get the best antenna for your location in a city you’d be best off with a 2-6 dbi antenna. This will allow you to connect with hot spots that are both vertically and horizontally near you.
In the suburbs you’ll be best off with a 4 to 8 dbi antenna.
You won’t need quite as much vertical range as in a city so this provides a good trade-off between the horizontal reach and vertical beam width of the antenna. And for a rural environment we recommend the 8 to 10 dbi antenna. This will offer maximum range for reaching those far away hotspots Wherever you plan to set up your miner it’s best to head over to HotspotRF and run one of their simulations to get an idea of how your miner paired with your antenna and your cable will perform in your area.
We’re in the USA so we’ll pick 915 MHz for the frequency.
We’re going to use one of our Rokland 8 dbi antennas, let’s set the height to a conservative 10 feet and for the cable loss we’re going to put 0.6. Where do we get that 0.6? If you head over to rokland.
com, go to our helium mining, page scroll down until you find the cable you want, in our case we’re doing the 16 foot 400 low loss cable, we’ve done the math already, this one loses 0.6 dBi. So we’ll plug all that in. Select your terrain we’re in the suburban area, so we’re gonna put suburbs and we’re gonna simulate this location. This will give us a good idea on if we should go with a higher or lower dbi antenna, if we should possibly raise it higher, if we’re getting a lot of dbi loss maybe upgrade to a better cable with more shielding, we actually cover this in the next section.
So it’s still running the simulation and once it finishes we want to look on the simulation output on the right.
So we’re able to reach three hotspots and we’re also getting a reward scale of 0.93, this is a 0 to 1 scale, so for this scale we’re doing pretty well we’re close up to 1. You can run the simulation a few times changing the variables to see the best options for setting up your hotspot. Once you upgrade your helium hotspot antenna the next most important upgrade is a correctly shielded coaxial extension cable.
So, what is shielding? Shielding is what prevents electrical interference. The higher the shielding the stronger the signal sent from your hotspot. As you can see in this photo there’s braided shielding that goes around the length of the cable to prevent electrical interference cables come with different shielding grade ratings: 200, 400, and 600 are the most common.
Choosing a cable with a higher shielding grade will offer less dbi loss, however, it will require more raw materials to produce this cable, thus the cost will be higher.
Let’s take a real world example of dbi loss at 30 feet: with 200 grade shielding you’re looking at about 3.0 dbi loss per 30 feet with 400 you’re looking at about 1.1 and with 600 we get down to 0.75 For a real world mining application with 30 feet of cable we would want at least 400 grade shielding, but what if we went with one of the cheaper options like RG58? What kind of dbi loss would we be looking at?
We’re going to show you with a calculator how we find the dbi loss of our cables.
So here we have a 400 grade shielding cable we put it in for 30 feet. For our example we’re going to set the frequency to 915. And go ahead and click calculate, you’ll see just like we have on the screen 1.175 dbi loss, but what about this RG58 cable?
These are cheap and you can find them online for a lot less price. Oh, yeah, now we’re looking at 4.65 dbi loss for 30 feet. That is a big drop, that is something you’re going to want to avoid if you want to stay profitable with your miner. Let’s consider this hypothetical example.
We’re going to set up our minor in the center of the city and use an omnidirectional antenna to send out radio waves in all directions to interact with as many hotspots as possible. This is considered the ideal scenario, however, there might be a mountain range or something behind you, and if that’s the case you could try and use a directional panel antenna to see what kind of results you get.
But I would still recommend first starting with an omnidirectional antenna and seeing how many hotspots you’re able to interact with. Much like we’ve had to socially distance due to COVID, you’re going to want to socially distance your helium Hotspot miner. This is because when miners are within 300 meters of one another they compete for network coverage, so spread them out, don’t let them get too close, or you’ll lose out on your hnt rewards.
It’s a good idea to look on the helium Hotspot Coverage Map.
This will show you what is near you and what other miners that might be in your area of network coverage. You might not even be best to set up your hotspot at your own house, maybe you need to borrow a room in your parents house or a friend’s place. Your goal should be to find the most advantageous place to set up your miner. So there you have it the top five do’s and don’ts of helium mining.
