- Update: Don't do this mod as I showed in this video. I will have a follow up video soon showing a better solution that won't damage your radio.
The upgrade I've been waiting for. This is the one thing I feel like my Radiomaster Boxer was lacking, an internal antenna. Does it have worse range? Yes. Am I still going to use it? Absolutely. Watch this video to find out why.

why is there a big cencored square over the inside of the radio? whats the point of holding it up if youre gunna blur it out?
My only concern would be that having your internal antenna mounted so close to (within a single wavelength of) chunks of metal such as the heatsink is probably going to mess with the SWR and if you're running a watt in the module then you risk overheating/damaging the RF output stage. When you get reduced range for a given power level you have to determine where all the power has gone. It's either reflected back in to the RF amp due to a high SWR or you've got a radically distorted radiation patern and you're flying in a null-point. Neither is desirable.
I think I'll be more than happy with the tiny antenna poking out the top of my Boxer 😀
Yeah that definitely concerns me too. I’m planning to take out the rp sma adapter and mount it near the top of the radio. That should improve it quite a bit.
I've blurred out the image of my mod. I'm going to revisit this with a better solution. I agree with you that was way too close to the heat sink and sma adapter.
@@stingersswarm maybe a foldable desing ?
@@stingersswarm I did a TPU print in the plug for SMA and mine sits right at the top of the radio flush. it fits nice and shouldnt have any interference issues. will ping ya a pic on IG.
Great to see the results, even if it wasn't an overwhelming success. Thanks for sharing!
Haven’t received my boxer but I ordered some commando 8 antenna shells with the intention on doing a foldable antenna. Nice to know I can use a regular RX antenna internally.
I've blurred out the image showing my mod. Don't do it like I did it. You need at least 2cm ideally 3 between the antenna and any substantial metal.
I've noticed that running over 250mW ELRS can cause interference with HDZero receiver. It depends on the radio antenna and how close the antenna is to the goggles. I'm curious if you've noticed this? Personally, I haven't had too much trouble at 250mW dynamic power on ELRS. Need to have rx antenna in a good spot I suppose
Awesome Kevin 👊🏻👍🏻Can’t wait to see the next one

I did this right as mine came in last week. Did a lot of research on the different antennas I could put in it before hand. I've actually had really good luck currently but I haven't put it through any intense testing yet. Thus far though it's been great for travel not having to deal with the external antenna.

@@stingersswarm I actually have a fairly large flat PCB antenna that I glued down inside. It's fairly directional and not pointed optimally, but Its been working great, I was flying a mobula 6 outside from inside my house on 25mw and it outperformed my video link no problem.
I have a couple other antennas coming in to test and will definitely share my findings
I use a stubby 2.4g antenna on my elrs module on the back of my Tx16s. It's a 2dbm dipole about 1 inch long. The radio fits inside the case with the antenna on and I never have to remove it. Yes it gets a tiny bit less output power than the T style antenna, but at only 100mw power I can still outfly my video range on all my quads. I originally got it just for inside whooping, but it actually works fine outside too. I hate having to put on antennas before flying!
Nice I'm glad it is working for you. I've blurred out the image showing my mod. Don't do it like I did it. You need at least 2cm ideally 3 between the antenna and any substantial metal.
I did the similar thing with my Radiomaster TX16S and Jumper T-Lite. However I used some 3d printed parts for both radios to glue a stickable foil 25*9mm foil antenna.
Yeah probably a better solution.
a solution having both would be cool, too. It would protect the RF modul in case you forget the external antenna. And you would exten the range if you choose to use the external in addition to the internal antenna.
Do they make a upgraded antenna for the boxer or can i use any Rp-sma antenna
I did very similar thing to my mambo. I have ELRS module in the bay and I ran a little custom antenna inside and ziptie it to the tracer antenna inside of te radio. Never had any problems with range and I do a lot of mid range and bando flying. Running 250mw and 250hz all the time.
Glad to hear it. Just to be safe i'm adding this disclaimer. I've blurred out the image showing my mod. Don't do it like I did it. You need at least 2cm ideally 3 between the antenna and any substantial metal. I'm going to post a follow up with a better solution.
thanks for sharing! Would be interesting to see performance with a T-Shape or Diamond Shape Antenna mounted directly to the inner shell of the radio. Maxing the antenna und distance to the rf module.
Great suggestion! I've already improved it. I'm going to test it today and post a follow up.
I was only able to get one of the 4-in-1 Boxers. So I am actually interested in putting a spare ELRS PCB replacing the 4-in-1 in there.
I hope they sell them.
Love this for backpack-ability. Looking forward to seeing the updated version of this with baited breath. Mine doesn't fit in my backpack without removing the antenna, and I have this nagging voice in my head saying "500 mating cycles"...
I have a small case I use which holds my Hdzero goggles and my Zorro in one compart. (Other combos fit nicely also. DJI/boxer etc)
This enables me to keep antenna on all the time.
Nice I'm glad it is working for you. I've blurred out the image showing my mod. Don't do it like I did it. You need at least 2cm ideally 3 between the antenna and any substantial metal. I'm going to post a follow up with a better solution.
If I were to get the boxer should I get 4-1 or elrs
I’ve been considering something like this on my TX16s Max MKII. I have the internal 4 in 1 and the only thing I use it for is USB dongles for simulators.
Don't do it like I did. Make sure it is at least 2-3cm away from any large pieces of metal.
My radio has dual internal omnidirectional antennas. I can fly out a half mile on 100mw. It is great not having to worry about antenna position or breakage.
Nice
I plan to just run the crossfire module in mine when they finally come out with the glitter version with AG01. so Ill probably just put a dummy load on the SMA

Wish they made the antennas like the Nirvana had it, folding into the body of the radio while in transit and folding open when flying.
The zorro is like that.
@@stingersswarm My tx16s and t-lite aren't 😁
True, it shouldnt be that hard, and not even that pricy to make. I completly agree with you

Im looking foreward to it!
I have the Radiomaster Boxer on order, I also have the stock antenna for the FrSky X-Lite on order. Going to mod the Boxer with that antenna and see how that works. I would like an internal antenna on the Boxer like the Mambo.
The gray box made me scared, was it that bad or did radiomaster say don't show that to anyone
I have a noob question for you. Could you just replace the stock antenna with a immersionRC red stubby antenna
Are you gonna try the CNC gimbals for the mambo from pyrodron?
Nope. They keep the same sensor which maxes out at 250hz which is a 1/4 the speed of this one. Plus that sensor has known drift issues. 🤷🏻♂️
Why do you blur out the video when you're showing the inside of the radio?
I did the AG01 but won't do an internal antenna. Room in its case for antenna. Still, good to see the penalty of moving it internal.
Yeah don't do it like I did if you do. I'm blurring out the image and going to post an update with an acceptable internal mount.
Be ultra careful when removing the UFL connector! I accidentally ripped off the UFL connector from the main board. It was a massive pain in the ass. The connector was destroyed and I tried to strip the mini antenna and soldered it manually but the range was hugely affected. I've made my own helical antennas before easily so I doubt it's my poor soldering. I didn't get any antenna warnings either like Taranis would give. I'm going to order a new UFL connector but in hindsight I caused a load of trouble with no results
I removed the SMA connector from the antenna mount and drilled two holes in the mount. Then I removed the plastics from the original antenna and took out the pcb with the half way antenna. ( one side ground and one side signal dipole). Put the signal rod thru the holes and the ground rod to the left. Works perfect for my distances with planes within 200m( appr. yards). Anything over this distance is of no use for me with my eys. Our max power in Sweden is 100mW/ 0.1W. 1W will give you approx. 3 times that distance if your drone is not extremely noisy on 2.4GHz. I never use external antennas today. Regard that as stoneage. No external antennas on mobiles either today. Nice that it worked for you also.
I'd probably design a small 3d printed mount for the sma hole to get vertical polarization with it tucked against the body of the radio.
Sang did just that. I've blurred out the image showing my mod. Don't do it like I did it. You need at least 2cm ideally 3 between the antenna and any substantial metal.
TrueRC do a nice flat T style antenna which would be easier to package in might even be able to mount it vertically as well. Having an internal antenna does make a difference in useability.
I'll take a look at it. I've blurred out the image showing my mod. Don't do it like I did it. You need at least 2cm ideally 3 between the antenna and any substantial metal. I'm going to post a follow up with a better solution.
I would use flexible antena and stick it to the radio plastic shell. It would then have direct view outside from the radio shell, also would be further away from internal radio boards. And those antenas are designed to be used on the plastic housings, so they they get prefect frequency tune when glued to plastic wall. while others get detuned from optimal frequency. For example DigiKey has some to sell. Like ANT-2.4-FPC-LH100UF or ANT-2.4-FPC-LV100UF antenna. I filtered out some 53 different models DigiKey has in stock.
Yeah. I've thought about that. I'm just not sure if I'll pull the trigger on that because it would block the vents for the cooling fan. I've blurred out the image showing my mod. Don't do it like I did it. You need at least 2cm ideally 3 between the antenna and any substantial metal. I'm going to post a follow up with a better solution.
Losses and gains are always dB, because they are realtive values. 3 dBm is an actual rf power of ~2 mW.
dBm means "dB relating to 1 mW", so 3 dBm is ~Faktor 2 * 1 mW because 3 dB (power) is ~Faktor 2.
What do you mean "solution that won't damage your radio" if the antenna is close to metal the radio can be damaged?
I bought a 2.4ghz immortal t antenna for my tx16s elrs version
I was thinking of doing something similar, but with a moxon. Maybe cut a slit in the top of the radio so that the top blade of the moxon is exposed.
I can’t find a moxon that terminates to a u.fl. If you find one let me know. I’d prefer to cut down on connections.
@@stingersswarm ahh, makes sense.

@@stingersswarm im think I’m getting this one
@@stingersswarm THE ONE AND ONLY STINGY !!!!!!!
your closeups are blurry for antenna?
0:24 Thanks for clarifying that right away. It's all I needed to hear to not do it.

@@stingersswarm Excellent! I'll wait for it.
Still flying the Mamba!
but much more interesting, are you going to stick with HDzero :o ?
For now
So where's the follow up video?
I know sorry about that. I’ve had a crazy schedule with work lately and I haven’t really even been home during daylight hours. I’m gonna get the update done soon I promise.
Why doesn't somebody make a folded external antenna for Boxer? It would be a great mod!
I'd love to see that.
yes, doing antena mod, no it wont be an internal one, will be using a happymodel variant and a 3d printed housing similar to nord ant mod video
Eyy.. He finally gone through it!
This weather we have hasn't allowed me to fly as much as I should and test the mod I did on mine..
My internal antenna is positioned vertical. I removed that pigtail and yep, it is a pain to remove.
Thanks for the test!
Finally he did it, and did it poorly. I've blurred out the image showing my mod. Don't do it like I did it. You need at least 2cm ideally 3 between the antenna and any substantial metal. I'm going to post a follow up with a better solution.
Maybe someday the Boxer will ship

I love the mod but probably going to play it safe until I break my antenna lol
I don't know, Kevin, but I think I've seen 2.4ghz internal antenas in some other radio... I just can't remember which... But they seemed to work fine. 🤔
Perhaps one of those (if they're available in the market) could do the trick! Because they were much bigger if I remember it right... You know?
I believe ELRS receivers use antenas that are 1/4 of the wavelength. A 1/2 of wavelength antenas definitely would work better.
Anyway, stay safe there with your family! 🖖😊
The frsky x-lite has an internal but, it's pretty similar performance drop. Mounting an antenna horizontally polarized next to pcb's is always going to cause loss.
@@thirtythreeeyes8624 That's very true.

just get a bog standard external folding rp-sma antenna.
I wish they should ship mine.... :(
Ordered from getfpv. They shipped Thursday and I received it yesterday, so yours is probably close.
Me too. I've blurred out the image showing my mod. Don't do it like I did it. You need at least 2cm ideally 3 between the antenna and any substantial metal. I'm going to post a follow up with a better solution.
Just did this to my tx16s max. Try using a tracer antenna. Haven't noticed any difference between it and the external. Way better quality than the garbage happy model and other junky elrs antennas. Also you may try pulling the board out and getting it on top of the board and closer to the front/top of the radio. Just my 2 cents. Also get that giant chunk of brass out of the way too.. if you can remove it.
edit: commented 1/2 way through the vid. def get that rp out the way and use a tracer mini t.
That actually is a tracer antenna fwiw
I will be removing the rp sma adapter. I just wanted to be sure I was committed first.

Thanks love
Thanks for making this video, been curious about this mod. 50% reduction is too much for me so I wont be doing the mod.
I don’t mind because I have other modules I can use in the JR bay if I need more power.
I’m also curious if I can improve it when I take out the sma adapter.

blurred out the giblets now I cant copy DAM😁😁
I’ve altered the install and you don’t want to run the antenna how I had it mounted for any length of time.
@StingersSwarm so radiomaster didn't give you a hard time lolz 😆
