Does the Antenna Matter? // LiteRadio2 ELRS 🤷♂️
In this case. This is the original light. Radio 2 to the express lrs edition was the upgrade board and at first i just left the original patch antenna inside here. So this is what the patch antenna looks like its just basically a sticker thats on the inside. It is on the inside of the casing. Right here – and this is the express cellar express lrs edition – light radio 2 unmodded. This is stock from the company, and this one here is the one that i upgraded, but ive replaced the antenna in there. As you can see, i pulled the patch antenna out and i put this dipole in here. This is actually from one of the receivers you can buy these in a pack of two, i think for like six or seven dollars. This is the same microfl connector that the original uses and the antenna is in the same location. In the case, its about right here like this inside and someone was wondering well um – is the range gon na be any different if youre, using if youre, not using the patch antenna, someone suggested you could drill a hole here and then you can use a microfl To sma connector adapter and then you can then at that point, use an external antenna of course, theres a wide variety of external antennas that you can use. Um yeah i didnt havent gotten to that extensive test testing. I wanted to sort of keep things more or less.
You know convenient so that the point of this radio is not to have a bunch of stuff hanging out and all that just keep it simple, so switch different patches to dipole here and wanted to see what the difference in performance is. So i did two flights im going to show you both flights im not going to tell you which ones which ill, let you guys decide, which one you think is the dipole antenna and which one you think is the patch antenna. So theyre going to be labeled a and b on the two flights im more or less flying the same pattern about the same distance um. Both radios are um. I think theyre configured for 50 milliwatts, exactly from both so thats. What you know i wanted. I wanted to lower the power, so i dont have to go super super far because on 100 milliwatts, its um, you can go really really far like kilometers away. So i lowered the power a little bit. So i could see the the drop in the signal and i am um using the patch antenna properly. I am facing the quad or facing the the passage of the quad. If you use the pattern chaining, you point at the ground, like some people, use the radius and pointing at the ground like this, then the patch antenna is going to be less effective because the signal is not going to be coming from the ground, of course, but In that case, the dipole will be more effective because the dipole, whether or not youre pointing at the ground its still going to be able to receive signal, and i did not.
Obviously i did not test that because its really going to i mean its kind of a given. If you dont point the patch at the quad, your signal is going to degrade and its just going to be worse. So i wanted to see in a comparison. You know if theyre, both if the patching is properly being used and the dipole is properly being used and pointing it at the quad whats the difference in the signal and thats what youre going to see here, two flights, a and b. Let me know down in the comments which one you think is which i will let the run. Let this video run for like a week or so and then ill come back and answer in the video description as to which flight is which but yeah im really curious to see what their response is going to be in terms of what you guys. Think of the differences between the two antennas anyway, thats gon na.
