Thank you so much for this video, my friend and I ended up winning 2nd place in an American state science competition centering around wireless antennas by using this design. You are my hero. 🔥🔥🔥
Best antenna guide I have seen ....very informative and upon following your instructions I have successfully made several of these for my quadcopters. Thanks
Same here. Took me an hour to find this video and it answered my questions completely. Was able to order the materials and repair my FRSKY xsr receiver to better than new. Thank you WildMania!
Thank you too. So, please share this video - out there are many desperate people who broke antenna, and don't know how to repair it. And many people who want better performance.
This is a VERY GOOD antenna design. The balun is very clever, as is the impedance-matching 'radial' element. WELL DONE! Easy to follow, too, especially if you know some antenna basics.
The part starting at about 2:04, I've attempted like 3 times. The first time I threw the wire away because I really messed it up. The 2nd time I cut the sleeve off and slid it down. The 3rd time, I actually did it well and it came to the correct length, too... while drinking beer!
"Through necessity comes innovation"........ And this dude is the master of innovation.......Awesome work WildMania this is so helpfull as are all your vids...........How to soar like an Eagle whilst surrounded by Turkeys.........;)
Yes, good point! Imagine person born in relatively poor country as is my country Croatia, then move to USA. New Nikola Tesla? Who knows?! I have no chance to move there... too bad for humanity :(
I'm trying to do Dipole antenna for a class project, what is the SWR and the Reflection Coefficient on this antenna? Also what did you use to match the antenna as the cable impedance is 50 ohm and the impedance of the Dipole are by theory 73 +42.5j.
I have no idea about SWR and how to measure it. For small transmitter (1 mW) for quadcopter, it goes over 1 km, so most of the energy is out, not reflected. Matching impedance is done by 1/4 lambda coaxial sleeve + odd multiplier of the rest of the cable as a impedance transformer. Also, note that this antenna and its dipole is not straight but rather at some angle - this helps bring down impedance a little bit.
@@mariofigueroa2110 Not at the moment. If you have some device with RSSI or any measurement, rather pay attention to good signal than SWR. SWR is okay up to 1:3, so no worry there. Usually manufactured antennas are around 1:1.5. Exactly because of complex number part... or, there is resonance and "anti-resonance" part if you look at voltage or current to or from the antenna. Pretty complicated stuff... :D
@@MilanKarakas I made the Antennas and they work perfectly. The TX have a Reflection Coefficient about -29dB with SWR about 1.2 and the RX have a Reflection Coefficient of -16dBi and SWR of 1.4 My only problem was that I have to use coffe straws and hot glue to make the dipoles more straigth in order to have a better Radiation Pattern. But these Video was great. Now Im making A Yagi Antenna for 890MHz to 960MHz with Gain about 12dBi.
Don't worry about SWR. It is more important that you have good transmission power and reception. Up to SWR 3 is fine, but above 3 is in danger. I watched many professionally made antennas, and every single has SWR exactly around 1.5 .Rather use actual receiver and if you have RSSI or other way to see whether it is good or not - if you measuring TX, then put 50 Ohm resistor as a termination on your receiver, lower TX power and make some distance between TX and RX. Then tweak antenna of interest (this time TX). Repeat the process with RX antenna, terminate TX with 50 Ohm "dummy antenna", or just solder resistor (small inductive reactance). Yagi antennas are really good. I should to make one video about dipole feed - the best I have found is so called "delta matching", where GND of the coaxial cable goes exactly at center of continuous conductor (1/2 lambda), and "hot wire" or feed at 1/3 at one end. For lower frequencies (say 144 MHz), you may add trimmer capacitor to adjust impedance, but for higher frequencies i tried and even without any capacitor it perform much better than feeding antenna by GND (shield) to one part of the dipole and hot wire to another. I am glad I can help. Thank you for comment.
GOOD JOB! Are you a Ham? This is essential / basic antenna theory and works on all freqs / bands. Feed lines such as coax being un balanced. Although we feed some HF antennas with ladder line which is balanced. Very good tutorial! For folks in the USA by law we are supposed to be a Ham to modify any wifi device. Part 15 devices i think it is are not supposed to have removable antennas. Just so your audience knows. But this is why so many of the older wifi routers are in big demand. =] WW5RM
The best way is to use 'gamma matching' if possible: www.google.com/search?q=yagi+gamma+match+design&tbm=isch&source=iu&ictx=1&fir=mSObcuVspB5CIM%253A%252CErgUUKqxQynucM%252C_&vet=1&usg=AI4_-kTYsowj3qHWBAA5rsjcPAxYV0UB0w&sa=X&ved=2ahUKEwif8ornm5bmAhUklosKHdgHBN8Q9QEwAHoECAcQBg#imgrc=mSObcuVspB5CIM: If small antenna, it can be made of brass or copper wires and solder instead making clamps and whole construction.
Hiya Milan, on the other video, the one for the sleeve antenna, did you use RG178, or the RG316? I wound up getting some 178 but finding it a little delicate to work with, so think I'll order some 316, may have a little better luck not damaging it stripping or burning insulation soldering, chuckle, real fine detail soldering not my strongest skill, it's far better than my painting, but I cant solder a house either
+Edward Hollibush I found the same issue - too delicate to work with. On all my videos, RG316 is used, except for FPV Mobius, where it is RG178 (single video). I wanted to save some weight, but amount of work on this antenna is... say three times longer if not more. Regarding insulation, it is PTFE or better known as Teflon. It resist temperature up to 260 degrees Celsius, and for short period over 300°C. Heh, not tried trick with flame - it just soften, but after cooling it back to its original state. Different thing is with razor blade stripping. It resist blade, but wires behind does not resist. So, yes. I understand the difficulties. But, RF and mechanical properties are good for use as an antenna, much better than other cables.
+Wild Maniac Well, i kind of misspoke, i meant more as you described kind of softens looks a little melted and gets a bit discolored, i just use the term burned for any distortion or discoloring of insulation, not actually blackened or flames, not the proper term for it I'm sure Thanks for answering man, I'm going to go a size up then and order the 316, BG has a 5M coil for 5.99, i just do little projects now and then, more repair, replace and minor improves than building or chop shop type customizing, you know, real simple stuff, umm i guess tinkering would be a good word for it, so 5M will last me a long time Take care Milan Ed

@@lionheartsummit284 The problem is that for every thickness of the cable, particularly central part - calculation is different. Also, if this part of the antenna is too thick, it will be wide in resonance, but quality factor and gain will decrease.
so can we split the into two antena for the transmitter? example are Mavic controller, or we use a wifi detachable antenna and solder the rp-sma m connector to the transmitter?
Milan, in your demonstration of the range you've been flying in a sraight line and have a staight line road/canal geographic reference for aiming the transmitter. What happens if you don't have such a good fix on which direction to point? That is, when reaching such large range, it must be very directional, right? How many degrees is the spread where the quad can receive at distance? Can the spread be increased by using more than one antenna?
+Dave Review Dave, you asked very good questions! Yes, I did it by knowing where it will end. But my other FPV flights are about half that range (cca. 500 meters only). Firstly anyone who fly FPV should build space orientation and mental image of where is the quad in respect to you, and where are you in respect to what you see on video feed from the camera. This way, you are pretty close to direction where it should be pointed. Also, my receiver has panel antenna which has four elements, thus pretty much directional. Just moving my helmet left right, and I can "feel" where video signal is stronger, but also where is my quad, so I orient remote to this direction too. In most cases of long range, I rather fly twice than circling around for example. Going say east, then back, then north, then back - rather than east, then circling to the south position. I don't know exactly how many degrees, but I know that as distance increases it feels more narrow. Another trick or secret of long distance controlling is in position of the receiver antenna on the vehicle. Away from noise sources: processor, MOSFETs, and motors. On transmitter (remote) side, it is done by slightly emitting more forward by "V" shaped element. Imagine donut shape, or toroid shape. If it is balloon, and if one part is squeezed, it is elongated, while the rest is shrank. This elongated part is where "V" shape doing this trick. No, more than one antenna usually result in more narrower beam (stacked antennas). In the case you want neutral beam, or omni-directional antenna, don't make "V", but instead straight dipole. As I said before, half of the trick of long range is in "V" shape, but other half is in moved antenna from the nose sources. Thanks for the questions.
+Wild Maniac Yes, I didn't think about the ability to slightly scan to and fro, as if to "hear" where the signal is received more strongly. And OK, so you are flying straight line and back as a practice in navigation. Thanks.
+Dave Review Yes, generally speaking. Once you have some feeling of space, then you can fly slightly out of straight line. And, with practice, maybe even more than just few degrees.
+Dave Review Not exactly. Single transmitter, with "splitter", which first split signal to two cables (each cable getting half of the power), and if needed - each cable to another two. Depend how narrow beam you want. One important thing is that all signals on antennas are in phase, otherwise it may end in bad side-lobe pattern. Two or more transmitter will result in bad interferences, since you can't control phases.
Hi Milan, I have a couple semi-off topic questions the green mat you are using, how heat and scar resistant is it? heat as far as any protection to counter underneath? (in case drop iron or hot glue gun tips off stand and not best time to grab, holding a soldered or glued part in place till cool/cured for example) scar resistant as far as say using an exacto knife to roll cut wire jacket, does it start to get a peeling off of top layer if it gets a few surface cuts from slips? (looks like scotch tape peeling up i guess is best i can describe what i mean) and I been shopping them at BG, but they seem small, what size is yours?
It can be used on a little vtx for micro quads?? (Eachine ef-02/ very little, 3 gr!!). I broken my omnidirectional at the base, the board cracked!! So I cannot resolder it. And I prefer this one that is less prone to be squashed. If I can resolder it !!! Will see. Thanx for this vid and I will for sure check out oiur stuff !! Have a nice day
This antenna is for 2.4 GHz band. Not for 5.8 GHz, if you think on analog VTX. Some quadcopters has 2.4 GHz WiFi video link, and only then this one can be used. Instead, if you have 5.8 GHz VTX - do this one: ua-cam.com/video/Rzumbr72xjg/v-deo.html
