2 Build and mount : This a demo of how I constructed my antenna for home use
3 Test and results: The the mobile signal booster antena and cable are put to test in a basement where there is very poor signal usually. With this setup there is a gain of around 28dbm. Which is pretty amazing for such a low cost home made antena. This helps in acheving very good and reliable signal.
4 Conclusion: Summary of the use cases where this may be useful.

@@jahangirhussain6870 hi, you could install an app from playstore for android, the name is "Lte discovery" , very helpfull and easy to use, it tell you the direction of the tower at you are connected too.
Sie, you are one of the few youtubers in India who is legit and work hard for your projects. You have all my respect and admiration. I was looking for a signal booster for my engineering project. Not only you made it really a fun task to perform, but also explained the things really nicely. Plus, the music was soothing, unlike that of the others who add EDM which makes it quite annoying. Thank you soooooooooooo much again for such a wonderful video. Hats off to you!!!
Dear Yuvraj, Thank you so much for your kind words. You made my day :)

Phenomenal video! Will be very helpful for people with poor Network reception.
I watched the video again and caught the spot I missed the first time through. Thanks again guy. I'm building this as soon as I can solidify what the carrier's frequency is from nearest tower for my phone.
What is the range of the "S" indoor unit? Does the phone have to always be on top of it? Also would it improve if it were connected to a larger metallic zig-zag pattern?
The dimensions given are for the half side or total length of directors dipole and reflector?
Thank you for the great video which I have learnt so much from. Looking forward to making one of these and thanks for the spreadsheet too.
can we connect two different frequency antennas into same co axial cable?
And also, there are some disc type antennas too, do they have same length and spacing
Thanks a lot for such detail videos. I like your presentation 🙏
I think I know what frequency the carrier here uses now, so I'll be modifying the yagi I built to accommodate that. Invaluable info. Thanks again. Ron
Hi sir I'm making the antenna and I'm facing some problems with the cable. There are two connecters what are those, I could not see it properly. And we use only the core cunductor in other end which is a single wire. It has 2 cunductors inner and core... What to do sir?
Sir..can you please explain how to connect the dipole to coaxial cable and how to use Balun for this antena and it's connection. Is there any method to amplify the received signals.
also how is this even working when the only thing touching a rod by the cable wirier is the one almost in the middle the rod which was the one with the most bends. the rest of the rods are not touching i wounder if some one were to use a aluminum rectangular pipe then all rode are touching each other look like to me that the one rod doing the work is the one that the cable wirier is touching the rest are just for show maybe in my case i need the booster part not just the antenna part but the booster pat and yes cost almost 300usd + the shipping to the country it needs to go at huhu
Pretty straightforward and clear narration. Well done!!
Thank you!
for bsnl Bannd 1 2100Mhz not working.. i make antenna two timesbut not worked. i fix antenna at 25 ffet height also try after change the directions... Help
What do u mean by saying "it was twisted in albhabet S"?and 2nd thing how to place the pvc towards the tower ?
Do we really need to match the impedance between the antenna and cable?? Kindly answer sir..
Thanks for sharing the calcs. From NJ.
Curious if this works only for GSM or if it will work for CDMA as well?
Awesome information provided 👍
This is just wow. Great work NJ.
Thanks Puneet for the everlasting support!
I wonder if you could split the end that goes to the cellphone (meaning make two "phone ends" connected in a "Y" to the antenna) so you could use it on more than one cellphone? Thoughts? There is a particular camping spot my wife and I like and the cell reception is very weak there.
Worth a try!
Thankyou very much, How do you connect the coaxial cable to the antena? it has to be connected in an specific part, I think you connect it to the feeder, but don't know how to do it
Hi Carlos,
Yes, the cable is connected to feeder.

Hello, how do you connect the negative and possitive cable wire to the driving element, is it shorted? Thank you.
I think one is grounded and only the main wire is used as a receiver pad thing.
How to connect the output coaxial cable to signal amplifier?
Where to get the cable from?
The sheet seems not working . I mean is not calculating the length of elements in mm on the right side column . Only calculating values in Lambda . For mm showing always the word #VALUE as result .I use OpenOffice to open the xls file.
The DTH cable have two mesh copper wire. How connect to antenna(dipole) and make the other S shape end.
Do I need to solder the each mesh wire to the both end of dipole individually and then combine the both wired mesh to make S shape end(for plastic card)

Hello Sir, I did not understand what to solder, what to solder?
I've designed 2 antennas considering 1800 and 2300MHz frequencies respectively.. But it's not working for me with any of the these antennas..
Shame problem with me
Thank you so much for this video
You are so welcome!
Hi, I see that the boom is not metal, thus there is not an electrical connecrion between the different parts of the antenna. I have seen otger videos of aimilar antennas and they use a metal rod as a boom,to where the other partsare welded. Couldyou please explain why this is nornecessary in your antenna?
Thanks a lot for the video!
Ideally the boom should not have connections to the Elements otherwise the response of the Antenna will deviate from the intended frequency. Usually there are corrections needed if the boom is conductive and touches the elements.
See more details Here: Yagi Antenna Insulated Elements Boom Correction: www.qsl.net/yu1aw/Misc/Yagi_boom_insul_corr.pdf#:~:text=Theoretically%20and%20practically%2C%20a%20Yagi%20antenna%20can%20work,antenna%20can%20be%20built%20in%20a%20few%20ways.
Sir can i ask if you need to connect the grounding(shield) on the antenna or no need
Yes, please connect!
Thank you very much i getting the i getting the internet
glad that it was helpful
Hi, Thanks a lot for the video.
I see that you have connected two wires of coaxial cable to each of the dipole ends. The coaxial cable that I have has only one central copper wire. How do I connect dipole to it?
One wire is the core of coaxial cable and the other is nothing else but the twisted wire mesh of coaxial cable
what kind of material the black one with electrical tape?? not specify in video
Yes, that's just electrical insulation tape!
Thank you sir
Well done, great tutorial .
Thank you! Cheers!
Sir how to make for airtel in Jharkhand .I'm not getting any information about frequency
Please see this: th-cam.com/video/WG4oDEI1_ms/w-d-xo.html
what kind cable we can use here . I have yagi antena for other end of this .
You can use a coaxial cable or your tv cable.
Hi Sir will copper result better than alluminium in all elements except boom ?
Yes Sir, boom should be non conductive. Use plastic or wood for boom.
I have jio sim so , so do I need to create 3 antena to cover all the 3 jio band(850hz,1800hz,2300hz) , or one will be enough. I want to use jiofi6 with better internet speed.
One will be enough.
Check which band has better coverage at your place.
Usually, lower is the frequency, better is the coverage.
Can you tell me the frequency band of bsnl 3g and 4g net work in Kerala
Kindly check here: th-cam.com/video/WG4oDEI1_ms/w-d-xo.html
What about conductor connection?
Can you provide link for measuerments of the antena? I am not able to find out that refered excel file.

Hi bro , if i use aluminium wire 2mm for Reflector , Feeder source and Director also if i join Feeder source in the end with coper wire 1mm , is it will work good ??!
Hi Arif, in my design, I didn't join the ends and it still worked fine.
well i think this might not work for me because the problem is the celltower are very fare and most of them are in red thy have a red dot which mean thy are giving out a weak signal and the green one are givng out good but there are so far that the net will get dis disconnected
Can please give me the details of Airtel carrier configurations how to build one .

Hi sir. I have question. Can this boost my modem signal using your setting .I'm using modem B618. I want my modem detect band 40. Mybe the tower very far. But here only have band 5.
And it's possible if I make two antenna will be better than 1? Can get more signal??
Hi Z Rose's
With Modem, I believe, you mean to say an LTE Hotspot device. If yes, the the answer is yes. It should work fine with that. On other end just try to put your device with different orientations to find location of your device antenna.
Two antenna, with a physical separation in mounting location should give better results. (This is called receiver diversity gain)
If it is not possible to mount far apart, you can also put the two antennas on same location with polarization diversity. Mount one parallel to ground and the other one perpendicular on side.
Hope that helps!

@@GeekyAndTweaky Thanks for your reply. Should reflector face cell tower or I have to place director fowards cell tower?
@@iMKPandey5 smallest director should be facing the tower.
Reflector should be farthest from tower.

Hai bro I have seen video of Kreosan English has making yagi antenna with circular discs. He's showing drawings with disc size and spacing. Does this really works if it works how he's calculating the disc size and spacing regarding bandwidth
Not sure about that bud!
Can you please review his video.
I am not much aware about communications and network
Very good bhaiya
Thank you :)
Sir.
I tried it several times, every time its getting fail to catch any signal.. mobile not responding with antenna or without antenna there is no change in netwrok strength.
There are trees surroundings to my house. But at the terrace of my house there is BSNL 3G network of 2 to 3 bars.whether the singal tower must visible or simply 2 to 3 bar is enough. Every time I was pointing the antenna towards singal tower. But there are trees surroundings... Plz guide...
How much you get usually?
@@pabitranaskar5967 at terrace there is 2 bar bsnl 3g nework... But inside house its nil...
Poison the trees at midnight.
THANK YOU Sir. The video was very helpful for me . The best part is that i made the antenna free of cost . I had a old power cable at my house from which i extracted the aluminium wire from it ...... Previously downloading speed was less than 2 Mbps and now i am getting average speed of 7-9 Mbps .
So thanks again .

नमस्कार सर, आप से कुछ आग्रह करना चाहता हूँ ,
antenna बन गया कम भी अच्छा कर रहा है परन्तु हमेशा antenna पर पक्षी बैठ जाते है और antenna की दिशा बदल जाती है , अगर संभव हो सके तो omni directional antenna बनाने की विधि बता सकते है .

Hello, outstanding video, very informative, well executed. Worth subscribing to. Please, some questions, if I may: As per your recommendation to dial on a Samsung phone *#0011#, in my case, 850, 1900 Mhz. Do operators change frequency when the signal downgrades to 3G, 2G? Would the Yagi required still be 1900? Can you recommend a booster (plug in type) and in house antenna? If the wire calculated by f/C/lambda x 0.0085 is 1.3mm, why do commercial yagis have elements (aluminum) that have 5 to 10 mm? Is it less optimum? I look forward to your videos. Thank you. Gustavo in Caracas
Hello Gustavo,
First of all, thanks for your encouraging words!
Operators do exercise load balancing strategies based on both signal quality and load (number of users in a particular cell/technology). So chances are, that a mobile phone may switch to another frequency band/technology while in use/connected.
When connected in a particular frequency band, antenna will perform better if designed to that particular (currently connected) band's dimensions.
Regarding those 10 mm sized elements: Usually, those sizes are for hollow pipes. Thickness of the metal will be typically between 1 to 3 mm range. What do you think?
regards

What was your cable length
Does it work at 15 MTR cable
I have tested it only upto 30 feet. I fear that 15 meters (~ 50 feet) may be a bit too long.
Thank s❤
May you provide thickness of alluminium rod?
Diameter = 0.0085 x Wvelength
hello sir, really great to watch your video but i have one doubt i have three different sims airtel , jio, vodafone. i was checking the frequency of all three different sims. jio was 850 inside home and outside home 1800 and 2300. airtel was 1800 and 2300. idea was 1800, 2300 , 2500. so im bit confused which frequency i should use.
Hi
Usually lower frequencies have better penetration. So 850MHz will give you better coverage without the antenna also. I'd recommend you go with 1800Mhz as that's a common frequency for all your SIMs
thanks for this insightful video. please which material is best for the directors? copper or aluminium?
shared this link and subscribed
Hi Bernard
Thanks for subscribing and sharing!
Copper will be best, then Aluminium.
Higher the conductivity better the material
Regards
G&T
Dear sir can you please tell me if such a device can be used for multiple mobile service providers
Yes, if they operate in same frequency band.
Aluminium rod size plz
In our area there is 2g service can i get 4g with then help of this antenna.. plz rply 🙏🙏🙏🙏
This can boost the signal only if it is present, may be low intensity. If there is no 4G in your area, then this won't help.
Can I make this using round copper dish
some people have posted such videos. I haven't tested personally
Nice info, thanks :)
From my house ,roof top to my bedroom distence arround 30 meters so can i use 30 meters coaxial cable ?? Is it work that much far distance??... please answer my question....
Dear Mayuresh, this long distance will cause some loss, but still it will boost to some extent overall.
If you have good signal at rooftop, it is still worth a try.
Yes .. I got 10 to 15 Mbps at roof .. but down no network and jio speed also .. sir can i use LMR 300 coaxial cable for that antenna ?? Please answer me ..
Then you should be able to get it with this Antenna.
LMR300 cable will be good for this purpose.
Thank you sir for your kind information..
Sir .. today I did measurement from roof to my room I can arrange these all system within 20 meter.. so still is tere any signal loss ??? Please answer my question..
Hi,
It did not work for me i tried every thing,
can you help me with this, i am using a cable which is same as yours and the rods are cut and placed at the same distance as you specified but i am unable to boost the signal for my airtel sim, please reply
Could you please share some pics of your setup
Sir can we use indoor antenna to retransmit signal
No unfortunately!
For that we need to amplify the signal before it can be radiated again. Which is complicated, costly and illegal (Unless we have an approved RF Device).
Great Video and excellent Design Spreadsheets!!! Thank you. Can you let me know how to have more or fewer Directors and their spacing and width? I was thinking 7 or 8 directors. Also, If you put another antenna at the Cell phone end of the coax could you have a little more mobility to walk around your office?
Hi Rudi,
Thanks!
You can find a table on this page which lists gains expected from yagi antennas with different number of directors (up to 15). You'll see that the increase in gain with every additional director is a diminishing value.
www.antenna-theory.com/antennas/travelling/yagi3.php
In last row of the table you'll find how to calculate the separation between the directors for different designs as a function of the Wavelength.
Putting another antenna on the other end didn't work for me. Despite the gain, the signal is still too weak to be radiated again effectively towards the mobile.
I think mobility won't be possible with this kind of passive antenna. We need an active booster fir that.
Hope this helps!

G&T
@@GeekyAndTweaky Thank you so much. The second spreadsheet is great too. I will be putting the receiving Antenna about 25M up on top of a tree. Coax is RG11 75 Ohm, runs down tree about 15M...Then per your recommendation, I will put the "S" contact antenna next to my signal booster that spends signal to house. I'm out in the country. Up in the tree my phone gets 2 to 3 bars. But no bars at the bottom of tree. I get LTE band 66. (1710-1780Mhz up and 2110-2200 down). So I'm going to design a yagi centered between at 1950Mhz or try a dual-band antenna with directors on top of a non-conducting boom centered at 1725Mhz and Directors under centered at 2150Mhz.. Any suggestions or thoughts?
PS, I subscribed to your Channel
I suggest you to keep the mobile over the cable & use blue tooth headset to take calls !

Very good signal at roof -95 dbm but too poor at ground room. I am expecting better response for jio in Maharashtra.
Dear Bharamu
Please solder the cable at antenna end for better results.
In your charging point are you use any WiFi or any other device
That's a magnetic connector for charging cable.
Thanks for the video. However, as you mentioned, mobility is the issue. We have to keep the other end of the cable always with the mobile. There must be some solution for this too. 😊😊😊
