ESP32 External Antenna Attachment Tutorial | ESP32 Long Range Antenna Mod | HOW TO

[@RobotBuilder100]

Great video! This is exactly what I will be doing today. I really liked the way that there is no pre-content and/or music. You get right to the content! I will be using an Xacto knife. Keep up the good work. Thanks, JD.

[@justinfudally4158]

Quick and to the point, great video and explanation!

[@KeithMildenberger]

This was really helpful. Worked as advertised and the detail is greatly appreciated. Tip about the glue gun is a great idea.

[@kc1fx]

Thank you for this. I was going to add an outside yagi point towards the outside 2.4ghz solar/UV station that I made. I had an old wireless print server that had the pigtail for the ext antenna. I did the mod today and signal went from -80dB to -53dB. Distance from router to device approx 125'. I am very pleased I did this.

[@chriswf]

I completed this mod to a couple esp32s. So far I have seen a noticeable difference in wifi capability! This definitely works! My esp32 is in a shop ~50 ft from my home, behind 2 walls. It monitors my solar panels. And it's acting as an access point for any device in my house that wants to connect and see the panels stats. The solar panel controller does come with bluetooth, but we all know what the range of bluetooth is like. :( So - I read the data with the esp32 then broadcast it towards my house. Before this mod, I didn't have a signal in my house at all. Couldn't even see the AP. Now, I'm actually able to get data - most of the time at least. I'm going to make a DIY biquad antenna for the esp32 and a raspberry pi in my house to see if I can increase both ends of that signal really well.

[@INOVATRIX]

Very nice 👌. If you want even better range you can add a 2.4Ghz amplifier to increase the range also.

[@ManishaPatil-l3q]

Sir can you please tell me how much range increase after antina ??? Approximately?

[@beststorytime4325]

no one never knows lol

[@jqzIII]

Old laptops have an antenna/wire set. Some a few. Great for scrounging they are.

Just found your channel. Excellent Content - another sub for you sir!

[@reshiram4562]

Does this help increase the range of Bluetooth as well or just that of WiFi?

[@MrRoma70]

Pretty sophisticated work, that made me laugh, lol

[@tba3679]

Made me stay to the end 😅

[@patilmm123]

is there a range test video? please share the link.

[@INOVATRIX]

Unfortunately no, it was a bit silly from my end not to do a range test but you can find other people's video on this easily.

[@geheimspionchase8658]

Does this antenna also extends the Bluetooth-range or only the wifi?

[@jyreprejoles7604]

Same question

[@geheimspionchase8658]

@@jyreprejoles7604 well i bought it and can answer now, it indeet also extend the Bluetooth range a lot. I used the module for am firework ignition system and autside the box the old esp had a range of arround 40-50 m insinde the box only 5m. With the new antenna i didnt test it to its limits but it went at least back to the original range

[@patonaranjo9394]

Hello, I have the same doubt. Did you find the answer to your question or did you test with Bluetooth to see if it increases the distance range?

[@OutOfNameIdeas2]

Should be same as they both use the same antenna

[@AMEGO]

Bro i have a repeater so my question is are this anteena for output wifi on input singnal from the router Im talking about stock motherboard anteena Im getting 1 bar i want to get more can i use this biuld to get strong signal

[@design8studio]

Thanks. Great explanation.

[@devilvortex1]

The antenna length must be calculated. Speed of light / frequency.

[@АлександрКопытенко]

Это так. Но... То есть, вас не смущает, что вместо разъёма ufl или тому подобного, антенна просто припаяна к дорожкам приёмника, из-за чего будут возникать дикие помехи?))

[@Dyrgrip]

Perfect! Thank you!

[@INOVATRIX]

Glad it helped!

How to do this on esp32 cyd?

[@ugurerdem9395]

Mesafe nedir? Antenli bluetooth mesafesi nedir acaba?

[@walt_the_dolt]

Are you sure the antenna wires are touching the contacts on the board? If it is only touching the solder, then it won't work because solder is not very conductive.

[@ArrehYhan]

is it also applicable to ESP8266?

[@Pomeranc-8749]

Yes

[@Ekozip1234]

did it work for bluetooth too?

[@mumbaiverve2307]

Hi, is there a follow up test video ?

[@istemihanmp]

a simple question if i dont plug in the antenna to sma adapter it will keep working righT?

[@INOVATRIX]

Yes it will work as I usually don't have the antenna plugged in while I am programming and testing the board. But I'm not sure about the effect it'll have on the range.

[@guntherschadow9383]

​@@INOVATRIXBut it can't work as well as if all was property impedance matched.

[@gazzacroy]

yes very helpful thanks for that :)

[@guntherschadow9383]

Did you match the impedance? The cable and antenna you use has 50 Ω impedance? Because I think that this PCB antenna is a 50 Ω antenna. And you are soldering to the antenna section, not the feed point. So you can easily screw up the performance to be worse than if you just leave it as it is. Although, I don't see any matching network, so perhaps there is no matching network needed because the PCB antenna might be 36 Ω? But you need to match the cable and antenna hardware to it. I checked your antenna link and there it says 50 Ω, and that would be fine if there was a CLC π-network to match the ESP32 pin impedance with the antenna impedance of 50 Ω, but there isn't, so I think they used a PCB antenna that is matched to the pin, not 50 Ω, which means you should be putting in a matching network!

[@techdad6135]

Will this help extend the BLE range also or just wifi?

[@alex59292]

It's a WiFi antenna…

[@jyreprejoles7604]

Bluetooth and Wifi have the same Frequency range (2.4Ghz). I think it will also extend the BLE because they shared the same antenna. What do you think guys? Pls comment. Thank you

Can i with Lora Antenna 915mhz- is compatible ?

[@edisonkho5874]

can it work with antenna operating in Ku band (12-18GHz)? can you suggest any controller that support this frequency range.

[@Elvishglint886]

That’s a lot of power and definitely is gonna be quiet large, like fit in a car not a backpack large

​@@patonaranjo9394same question!

[@allstar7778]

feel free to remove the antenna outer cover, just the wire enough will give you better range than before ofcourse less than full antenna but might be just enough for your purpose, this is helpful for tight spaces and gives you more flexibility

[@DroppinBeat]

Do you have a part number for the cable you are connecting? Where did you purchase it? Thanks

[@INOVATRIX]

It usually comes with the antenna but if it doesn't then you can search for it as "sma antenna extension cable".

[@khasuist]

You can give antenna from old router

[@PovGuy21]

Is that transmitter or receiver?

[@JoernR]

Transceiver, as always with bidirectional transmissions.

[@catursubagyo360]

If I look at the ESP32 the end of the line is one, I have tried it with 1 cable and the results are both good

[@hibahprice6887]

как это сделать на KRC 86B? Где там заземление, а где контакт на антенну, там всего одна дорожка(

[@unknownblueblue]

thank you worked

[@beststorytime4325]

What's the estimated range difference (in feet)?

[@tyjohnston5889]

About 600 inches.

[@DustyPhillips]

The mesh should be going to the shield.. it looks like both traces are positive for phase loading.. otherwise they would not be connected... You are shorting the antenna.

[@cheapmod]

he cut trace

[@melophile04]

wherer did you got that antenna buy link ? nd buy link for esp32 chip too ?

[@INOVATRIX]

It's all available on Amazon

[@TheGoodMorty]

Will this increase both sensitivity and output?

[@INOVATRIX]

I didn't check the before and after state so can't really say but it will surely increase the range although not by much.

[@TheGoodMorty]

​@@INOVATRIXI just mean, will this increase the range that the signal goes out and the range that signals can be picked up? or does it only increase the range signal goes out?

[@INOVATRIX]

Should help in both

[@jyreprejoles7604]

Model of the ESP32?

[@ManuelNogueiras]

It's looks like an ESP-WROOM-32 DevKit. You have also the "S" version with the antenna connector already integrated.

[@INOVATRIX]

Process should be same for that as well

[@paranoidzkitszo]

Way too much work and can't believe you don't know this but Espresif with their ESP32 boards did some cost savings which lead them to remove any external connectors they didn't see users utilizing its range...and maybe a few cents but if making hundreds of thousands maybe millions of the boards it adds up. BUT, what they did do....sure they removed the larger sma or ipex...but you don't have to do all that cutting/ scraping. Possibly getting cancer from breathing the dust(you did wear a mask while scrapping right? That black protective coating is highly carcinogenic)... but that black layer actually peels off leaving behind a couple small glue spots... all you need is to buy ipex connectors. The little ones.. and peel the black off- be care full...it's also very thin and difficult to do...once you do, just place he ipex connector on the glue spots...no need for solder either. Just take care with attaching the antenna and try not to have to disconnect reconnect too many times. Hope that helps.

[@MrTea42]

😅 back seat drive much paranoid. bro is working with what he has. the tiny pex connectors are convenient but might not line up with the trace pads. he could buy an esp with one already installed, or you can just let this man make videos in peace with you trying to be OSHA

[@vaibhavbhasin1221]

doesn't look safe steps.

[@INOVATRIX]

It does involve some risk.

[@wargakonoha2689]

​@@INOVATRIXWhat risks will be obtained if you apply such an antenna?

[@tyjohnston5889]

​@wargakonoha2689 Risk you're going to jack up where you scrape and if it's not in a box to protect the connections.

[@atmozphera]

what a crap job... buy a ESP32 with RP-SMA built.

[@chimeranzl9147]

what a dick comment

[@timfoster5043]

He's talking about RF, not WiFi. The WiFi module from Ghost has an ESP32 WROOM chip ...with built-in antenna, unfortunately. You'd have to do a solder hack if you wanted to add RP-SMA.
