For your solar power system the orbital period is roughly 90 minutes and the illumination period is 45 minutes.
If you only knew the true capabilities of this "cube" setup!
Hi @EngineerMeThis. I’m a final year student doing my final year project on design, fabrication and testing of a Helmholtz cage for ADC of small CubeSats. May I know the process of testing phase details? That would be really helpful for my final year project.
Can you share the editable .sldpart? I'm a Solidworks novice and cannot figure out how you did the swept feature with the shape. I'm attempting to redesign it for GPS L1.
in th-cam.com/video/OJy-XjGYlGw/w-d-xo.html you show a guide for turn the wires . Can you put the stl on thingiverse? i,m interesting on that sistem for buildld an antenna for tinygs mesh. 73 EA8DEC
really beautiful
Great building! Thanks!
What freq is this for?
Is there something like this for 137mhz?
ufb Good engineering job! I am always looking for an antenna, that meets the requirements and is small enough for neighbors view. 73 de Peter, DG8DZ😋
@EngineerMeThis just printed and put together the wrongest way possible... Hahaha still work's excellent for receiving and decoding Radiosonde weather balloon's!!!!! Excelent work!!! Do you have the stl files for a top cap and bottom bracket of some sort???
Nice work!
@@EngineerMeThisHi! The QFH is working flawlessly!! I asked the guys who printed the antenna for me to create the top and bottom(for tripod/screw mount) covers! I have the .STL file if anyone wants it.
Oh! What a nice build. I would wish a tutorial like this for a 137mhz build. Do you have any plans?
It's in the works! trying to accommodate people with 220mm build volume so making it modular
Look Forward To seeing test results on VNA etc. Have you upgraded this to another version?
In the process of the next ones that's abit more refined
From looking into it a bit the helical antenna would be very directional and is supposed to have higher bandwidth, but for some reason this one doesn't have higher bandwidth. Is there any comparison with a patch antenna? It seems you could make a patch antenna from a cut up beer can that would have coverage for the whole sky with less gain, but would be much more directional in the right way than using the dual band or 1/4 wave antennas recommended on the tinygs site.
Hey, I think you might be mixing a normal direction helical antenna and a QFH helical antenna. A Normal helical (which is another video on my channel ) is directional and very narrow beam. The QFH antenna has two coils in either 0.75 or 1 wavelength. This is a very omnidirectional antenna and nor comparable to a patch or normal helical antenna
@@EngineerMeThis I made your antenna design but ended up resonant at 402mhz with narrow bandwidth. It is improving reception on TinyGS and is still picking up some satellites on 433 but is doing best on the 400 mhz
@@GuyMasong1 Thanx for trying it out, I agree it tends to be much narrower then expected. but on the freq side, thats by design. if you have a wide spectrum to cover like 400 to 440mhz you want to be on the low side and being on the high side means you wont get any of the 400mhz freq. the issue as you stated is the narrow nature.. im testing new designs with better efficiency and wider band. so stay tuned.
I would be interested in the actual tested gain of the antenna. It occurs to me that the material you're using for the form (PVC, or maybe ABS) is a dielectric and since it's in the middle of the field, could effect the performance.
Hey Hey. This material was PetG. and the contact surface on the cover coil itself was limited. Performance is great with real work tests and has 100mhz usable band. with regards to the dielectric. Yes it has impact but it can be accounted for to a certain extend. This specific antenna has a biggest impact on the impedance matching part but minimal on the coil it self. I'm yet todo gain testing but would be happy to assist if you have the equipment and time todo so
Very interesting. I have a need for the same type of antenna for Meshtastic, US 915mHz. I used Matlab's Antenna Designer software which has the ability to optimize the design parameters for gain, bandwidth, etc. I was able to get a gain of 11.1 dBi. The parameters are as follows: Radius 0.069493 Width 0.00278 Turns 3 Spacing 0.09731 WindingDirection CCW FeedStubHeight 0.001 GroundPlaneRadius 0.20852 Tilt 0 TiltAxis [1 0 0] Matlab provides an S(1,1) plot, as well as complex impedance, but does not show how to match to a 50 ohm Tx source. Any pointers would be helpful. I think your construction methods are very clever. Having a VNA to validate the design is helpful, have a Siglent 1032x standing by.
Large Portions of this video has no Audio.
This seems to be a TH-cam playback issue. Couple of people have commented on different videos but lost are fine. I suspect it's music copyright sections where they deem it needed to block it and then loose all audio as result
@@EngineerMeThis 🤬 TH-cam (KGB) .. I give them 👎👎👎👎👎 for messing with your video.
That 1/4" Tubing should be "Ridged Enough" to hold it's shape.. No need for the 3D Frame other than to help form the Elements perfectly... (Cut Slots) top and Bottom to Slip your Formed elements out after forming. (only thing) you will have to (Cut) and solder the ends at the bottom as well when installed into it's final Mast.. (Nice Idea) this QFH should perform the best for the TinyGS 👍 It will have a Perfect Radiation Pattern for Satellite RX. I use one like this for NOAA at 137 MHz (Very happy with it)
I agree with everything you saying, just remember the point of this project was to dielectrically load the elements with plastic to reduce the overall antenna size. So if I remove the plastix the antenna will no longer resonant at 400mhz. But your points are still valid and I'm working on version 3 so will def be taken into consideration
@@EngineerMeThis I hope you create a video Showing it's Performance and Resonance with your VNA. Along with a 3D printed Helical Radial Former (and willing to share the files 🙏) I plan to make one to hope will resonate at around 425Mhz ... But I cheat and use elbows for the 90 degree bends. A forming frame (for one Radial at a time) would be slick. (Subscribed & Notifications are on) So... I'll be Waiting..👍📡73s
*¡¡¡ ANDA YA !!!*
Could you build me one of these for 300mhz?
What usecase do you have for 300mhz ? You should just be able to scale the size larger for 300mHz as a quick fix
@@EngineerMeThis used for SATCOM
could you please send the STEP file
The solid works file is already loaded
This is RHCP or LHCP
RHCP
Hello, compliments for realization. Have also the 137 MHz version?
You are not the first person to ask this, I'm looking at it. The issue is size. You would need to split and print this antenna in 6 pieces with the current design. So I'm working on the princple to see if different method can be used
👍@@EngineerMeThis
A 137MHz version would be fantastic. I appreciate the step-by-step video. Thank you.
Bummer about the cheap GPS chips is that they auto-lock above specific altitude and speed limits to prevent their use in aerospace applications.
Indeed. I think if we were in a world with no dark side we would have access to alot more cool tech we don't even know about
Hey brother I am a student that is just building a cubesat for a hobby on my own I invested alot of money into it already and I love how you break down each component of everything. is there anyway I can reach you ?
Email is listed on my page
Not being a radio guy, I just printed the print in PLA, and just used ordinary multistrand electrical wire… soldered ends together on the bottom. Then just soldered center and shield of coax to the wires on top (as shown in video). No balun, No tuning or anything, I have no instrument. Then connected it to TinyGS Lora Satellite Groundstation, and it just works 😊. Receiving 20-80 satellite messages daily 😊 (It is just hanging inside, in front of a window, using a nylon string) Receive only. Thank You 🙏👍😊. Best wishes from Norway
The audio disappears at 4:26. I have tried youtube app and on different web browsers. Same everywhere. Weird
*** Enough with Vertical video shorts that are annoying !!! *** Please use your phones HORIZONTAL mode in future !
Looks like a gyroscope to me
Gyro for stabilisation
Hi, I've build one and it receives well, after three years I am back, receiving satellites again. I will try shrinking this for the 868MHz and will go after INSTANBUL satellite 🛰. I use an old Tbeam at the moment. I understand there are some with LNA and better chip like SX1262? Can you recommend something better? 73 DE1CTL
I just wrote my report here… ( see latest video comment). Using TinyGS on 433Mhz in southern Norway. Have you modified the model to 868MHz yet?
A motor in a gimbal in order to vector steer thrust?
Very close! But not exactly. It's the beginning of 3 Axis Gyroscopic precession stabilizers..
Shoulder joimt?
nice QFH sat antenna
hmm.. wonder if I can make a 10m version... lol
whats the use of a QFH at 433Mhz? I am interested in building a QFH for NOAA APT and see some Space pictures but I don't recall what this antenna would provide at that freq.
I have built it and use it on my TinyGS. Receiving 20-80 Lora satellite messages per day.
@oljobo I looked up tiny gs and Lora. Neat project but not a lot to do if it's just packets of satalite heath and status.
@@tratzum yeah true 👍😊
Can you please send a link for the connector you used to join the antenna 18:17
This is a great Video Have you made an instructable? Whats the best way to contact you.
very nice ... thanks for the well done documentation ... but the sound/voice fails may times ...
Hey there, thanks for your hard work on this! I'm wondering if it's possible for you to modify the STL so that the holes at the bottom where the copper tube is fed in again are open-ended. It would make it a lot easier to bend the pipes in. I tried doing it myself but didn't have much luck. Would really appreciate your help with this! * Maybe if possible also provide a STEP file please.
Hey, I can do so, I found it easier just to cut them open after the print has completed. Cutter into open slots instead of holes.
Hi, please is it possible to purchase the energy harvester board and the solar panels?

Hello Sir i need you help with some clarity i am trying to make a Helical antenna for 2.4 Ghz band (2400Mgh) but the calculators on the internet seem to give different values for the different measurements and diameters. And the other is am having some dish old huge dish laying around so i also want to make a helical antenna for digital Tv setellite channels but for this i have no measurements. is it okay if you could guide me on this. for my builds i wont use 3D printed frames I will use simple plastic in center. Thansk in advance
What is your preferred circuit design software? Thanks!
The sound dies at the beginning of the video. Great project though, I’m super excited to try it
