Why low gain antennas are great for Helium hotspots?

[Songs] why do i like low gain antennas maintain it basic maintain it real that'' s really what i desire to do currently the whole topic of high gain versus reduced gain is potentially fairly controversial so i'' m simply going to walk gently below and just want to claim i like lower gain antennas due to the fact that high gain can be flawed with a whole lot of threat and also mistakes [Songs] i'' m not speaking experts below so if there'' s an expert viewing this video i'' m with you high gain is excellent yet high gain is great if you if you have the right antenna and you establish it up appropriately and that'' s where the issue is that like with helium presently in the helium network you have a great deal of installers as well as setups that might not have the right option as well as there could be choices of antennas available since there'' s obviously an entire boating of options available currently free web sites not free however low-cost web sites as well as unidentified brand choices available as well as you can have a great deal of blunders i just want to describe what is potentially going wrong if your high gain antenna that you acquired on online is not doing what it'' s doing so on the screen i have a radiation pattern that i gotten from a chinese manufacturer when i was just checking out things and also would like to know what'' s going on on the antennas and also without naming the precise firm what involved here it'' s simply a maker basically they sent me this variant pattern as well as a hand on heart set that'' s the antenna this is what you will get if you get a 5.8 or 6 dbi antenna currently if you check out the story on the left you ' ll see it primarily has a little bit taking place the horizon but it seems to have a big bubble going up in the direction of the leading to make sure that the plot in the center and also on the right is the 2d plot of the very same antenna and it has numbers there so you will see that it says maximum 5.6 dbi so in principle in antenna world yeah that'' s great i guess you can escape claiming it'' s a 5.8 or 6 dbi gain antenna it won'' t actually you won ' t see'that difference since that ' s just 0.3.4 db however the big issue is where is the power going so you buy this antenna under the assumption that your gain is going left as well as right so on the perspective and also when you mount it on a on your post you assume this is'going there so you look at this it ' s it ' s not overshooting as well as all those words that you obtain however this antenna is simply gladly increasing right into the skies so concerning 30 levels up so you are generally attempting to generate iot signal towards the neighborhood aircrafts overlooking this is pointless and afterwards imminent simply look at the numbers imminent if you actually look take a close look it'' s in the negative adverse tbi variety so why this occurs is is you really need to do a great style when you go higher because you have multiple aspects you have a component here and ahead and also on the top each of them needs to be appropriately delighted or fed with a wonderful feed network if you have the phasing incorrect if the range is between them is wrong as well as the spacing is wrong between the aspects which is actually component of the entire appeal of the style you can'' t just have a resonator that does great at 900 megahertz as well as put 2 of them together and also just say i'' ll simply feed them with each other you need to have the spacing proper as well as you need to have the phase in between them with the feed network appropriate so there'' s two points that is truly crucial as an antenna design firm if you wear'' t do that this is the type of stuff that'' s going to take place um it'' s just going to damage totally so there we go that'' s a high gain antenna it ' s a 5.5.86 dbi gain antenna you can acquire it for economical on the web from some of the like ebay as well as so forth you'' re most likely to get that not terrific not terrific in any way so why do i wear'' t like low gain firstly the variant patterns is most likely mosting likely to be a lot extra foreseeable to be perfectly sincere i'' m loving the h antenna i have one running here and also i have a few clients here in adelaide also running them as well as the results are extraordinary first of all the gain that you hop on the perspective with a single antenna is going to be what it is due to the fact that it'' s essentially an excellent trustworthy dipole tolerable in any way so left wing is just a screenshot extracted from the um mp antennas or h antenna internet site you can see it'' s simply a traditional dome in contrast to the previous photo that i had which was all over the place and also in fact going 60 levels up this is a nice grain so you understand you have three dbi and also it'' s mosting likely to the perspective that'' s what you anticipate whereas the other antenna which you place on your roof you believe it'' s a 5.8 so you set your system your healing hotspot to have a 6 dbi gain suggest time on the horizon is -3 this is 6 dbi much better since it'' s a far better interior um and afterwards if you see the 2d story which is the cut simply it does does it does exactly what it requires to do on the riser as well as to rather gladly um setting up now the range there simply to to to be fair the scale that they use on that particular story is in fact simply a recommendation to zero that'' s not an absolute story that obtains done a lot in the net so people will certainly tell you this is a 3 vibrai antenna as well as there'' s the radiation pattern so the pattern might be stabilized to absolutely no and after that you just have to scale everything so the maximum equals to in fact having a 3 dvr gain so it'' s 2 various means of taking a look at that'that ' s the h antenna which is a low gain antenna and it ' s doing truly well however don ' t take my word for that allowed ' s look at a few of the outcomes that we are seeing in in in adelaide so this is really it'' s not mine yet it'' s a customer of ours that is um living nearby um he replaced a high gain omni with this reduced gain omni searching for much better insurance coverage in his immediate vicinity since undoubtedly as we know and over it doesn'' t overshoot but you still have better protection in your instant base listed below you [Music] and you utilized to get a web link to what we have it'' s called dublin it'' s not doubling in ireland it'' s simply a very tiny community up north from adelaide about 70 80 kilometers far north currently the story that i reveal on the display we still get all what we the customer and that particular unit still obtains a link to that 80 kilometer link so we are having a 3 dbi antenna positioned at a good placement still having an 80 kilometer lick currently it is essential to keep in mind that the rssi is lower so we can see that it really has um you know reduced the the number the power level that goes there however you still attain those kind of sizes at ranges with a 3dbi h antenna that'' s sort of what extra do you desire since the important things is if you consider it and also this is this is now me talking from from personal viewpoint concerning iot and also where points are um you understand intended to be heading for for iot and also helium as a whole you desire your base station you want your hotspot to be servicing all the gadgets and points that you remain in your immediate location so let'' s say the 10 kilometer distance around you which is currently rather a big radius you desire everything to visit ground there you desire everything to happen there a low gain antenna is mosting likely to do that it'' s not that it'' s inferior it ' s really simply going to be better in your instant area since if you say well i can get with a high gain antenna a a variety of 80 kilometers and also this high gain have witnesses up at 80 kilometers i ' m not a iot device or software professional however i put on ' t assume that device will in fact have a really high chance of linking to devices on that particular that range so why would you actually attempt to get to that array where you can really obtain a low gain and also 10 iron surf your instant location so a lot better so i assume if you consider iot reduced gain is much better the least expensive that is still making good sense for you and also three or 6 those are both limits as well as i i directly for these kind of setups i i put on'' t always think 9 is is the means to go and after that there was an additional one i wish to reveal which is really one that that we utilize ourselves right here in the workshop however there'' s an image on the display as well of the antenna on the workshop right here currently you need to know adelaide to recognize how useful or incredible that is due to the fact that we'' re in fact on the south as well as south lags a little bit of a hillside people recognize it'' s that that'that ' s why they they look down on us because they claim are you people on the various other side of that hill and now that that white dot that'' s where we'are we ' re beyond of that hill yet we have um witnesses going around the town beyond so i'' m happy i ' m delighted this is h antenna once more it goes north and it goes south so it functions like a dream it covers essentially the entire of adelaide i wouldn'' t go higher there ' s just no no need for that as well as there'' s no need and it'' s really possibly going to trigger me a lot more difficulty because in this way i may not obtain the the regional connections along with i wish to um so i i guess simply as a point of view item why why am i so fired up regarding these points or why am i so concentrated on on reduced gain four especially helium i assumption initially of all it'' s simply iot is an extremely slim band application as well as since it'' s narrowband the level of sensitivity is remarkable and you can get truly low signal levels as well as still have a great link so gain is not the point that'' s mosting likely to make you damage it it'' s it ' s the iot things is such narrow band that you kind of wish to have a really excellent antenna where i think as in its entirety system layout your radiation pattern rather than that initial picture i revealed and also the 2nd image you want the 2nd picture because the pattern behaves basic tidy jobs well everything is going to just have a nice possible connection placement of the antenna that'' s that instance for the younger gentleman in that has the 8 financial link he'' s a little bit high up a hill he has a beautiful arrangement as well as the um the unit that'' s far away additionally has a wonderful high pole so antenna positioning is more crucial than getting a high gain antenna and after that polarization with this h antenna is just an excellent instance of exactly how points can be done because it hasn'' t put an awesome multi-polarization so it offers you extra um about ability that'' s what sorry capability to link 2 tools and also as i pointed out in my previous video the device can be vertical horizontal could be relocating doesn'' t matter but the polarization is going to be very important in the lengthy run so be mindful of that and you can do that much far better with logan antenna so once more there is an an additional advantage for going reduced gain you have extra control i could say even more composure in fact you can do even more things with the reduced gun as well as don'' t go all expensive on the high gain and then this is with any kind of antenna resistance matching as well as performance is so crucial h antenna does that well currently you can do that on a high gain antenna so that'' s not the situation that ' s not the concern whatsoever however it ' s simply if you have a negative insusceptibility match if you wear'' t have excellent antenna efficiencies there'' s in fact going to be extra losses that you um that you introduce that that will certainly that will harm you as well as with the logan antenna with web itself the structure is less complex it'' s a lot easier for us as developers to um maintain it easy as well as obtain it appropriate hi there that'' s a wonderful one keep it straightforward get it best i'' m mosting likely to use that going onward anyhow thanks for watching see you in the next video bye-bye [Songs]
