Great introductory video for this! As for Tracking app recommendations: I recommend just using SatDump itself. If you use SatDump for tracking, live processing, and/or recording all at once, you don’t need to look between multiple devices. Everything fits on one screen. Also, as others have said, that dish probably isn’t be best. I use the NooElec GOES dish for HRPT. It’s also not perfect because it has a linear feed, not a circular one - but I can still pull in HRPT signals with a SNR around 14-15 dB. In the end, though, all pre-built dishes at this time (that I’m aware of) are a bit of a trade-off without modification.
FYI, SatDump can decode, track, AND record the signal at the same time. Just make sure you have a decent computer or even phone/tablet as it's available in Android 😉
@@alphaadhito yes true, I just use satdump this antenna and android phone with sawbird+ external bias tee, and airspy mini, I get metop satellite 📡 good images, NOAA good, meteor good, metop takes longer to process images using android phone after tracking done 👍🏻
Brought the helical feed 1698MHz only from eBay a week ago and put it on a 1meter dish totally happy with it have read good things about the faraday cloth dish. Going to treat myself to the S band version with a Nooelec Ham It Down next
The faraday cloth "dish" looks too flat to focus on the helix to me. Perhaps it's deliberately not focusing too sharply so it doesn't need to be pointed too accurately?
@@SeedMedia-j9b I use airspy R2 with sawbird+, DC stop filter and external usb power supply. In this video there is only airspy mini and sawbird+ which seems a bit strange to me. Maybe lna does not give full gain with such a weak power supply.
@@maxxm.108 I found sawbird+ would glitch on and off using only airspy mini 80ma , so I just use external bias tee and 5v, I not bother with DC block never had any problem but good you use good logic and are careful 👍🏻
@@TechMindsOfficial any old TV dish with a helix would outperform this, or if you really need the portability there are "helicone" antenna designs, some solid, some that people made folding
@@SeedMedia-j9b Yes, but you will never have a clear picture as a result... have a look at the page he mentioned at 8:55 and see what is best for you. You don't have to carry it in your hand if you buy a speaker tripod for a few bucks.
That "dish" is nonsense. Almost the *entirety* of any antenna gain seen is from the helical feed. The only the the flat reflecor is doing for you here is flipping the chirality as seen by the feed. Wind the helix in the other sense, and point it directly at the satellite and you'll get as good or better. It's NOT a "parabolic dish". Not even slightly. The work put into this "dish" could just as well have been put into making a proper parabolic shape. But, you know, don't trust me. I've only been involved in radio instrumentation design since the 1980s, and run a radio astronomy observatory. What do I know?
@@TechMindsOfficial hi, I really like how you presented the process in this video and that you referenced one of the most accurate articles about HRPT at the end, but I would note that your title saying "parabolic dish" is inaccurate for everyone that wants to learn. Thank you.
@R1chae I didn’t make the dish, and that’s the description from the seller. It’s not entirely flat, maybe that doesn’t show too well on video. Not as deep as a sat dish for sure, but it’s not flat. Cheers :)
@@TechMindsOfficial oh I indeed didn't notice that it isn't entirely flat. it actually looks slightly conical at about 1:43 but as this gets worse signal than a 60cm tv satellite dish, I highly doubt that this reflector is even nearly the right shape to focus rf in this frequency range and personally I would still change the title to be more accurate than the listing. You could put it under quotes maybe, that sounds fun
@@patchvonbraun you could have done this without the last bit where you come across like a dick See how the rest of us are helping Mat without doing that?

The Faraday cloth and photographic tripod mounts are excellent design features. Thanks for the video and your time to make this excellent series.
Correction: Faraday Umbrella🤓
Genius idea saves me juggling the weight when hand tracking of my big dish 👍🏻👍🏻👍🏻

That dish looks a bit too flat... But it did the job!
Amazing 😍
Nice Job!

This can’t be this easy. Omg
Nice one Matt. 73 de F5VMJ.
Wish there was one that is c-band size haha
What were motorised dishes at the start of the video please.
Is that dish actually parabolic? It just looks flat, or at best a shallow cone.
Its flat. Simple small RHCP helix works better.
Portable QO-100 dish?

Sawbird+ draws 180mA via bias tee. Does airspy mini have that current capacity?
yes. I use airspy with sawbird.
You need bias tee or usb power for sawbird+ as airspy mini only does 80ma hope this helps 😊
@@SlawekKlimek55 With sawbird or sawbird+? Sawbird draws 30mA, sawbird+ 180mA.

here's what 4k without internet means
parabolic? I guess if you scale any parabola enough it becomes flat
Its very shallow almost flat
This antenna is not good at all for its price and size, I would advise against buying this
What would you recommend instead, for the price, portability and size?
If it works it works
@@TechMindsOfficial any old TV dish with a helix would outperform this, or if you really need the portability there are "helicone" antenna designs, some solid, some that people made folding
@@dereksgcI understand what you're saying but none of those fold like this umbrella, a traditional dish is heavy for a 15 minute tracking

How about Discovery Dish CROWD SUPPLY?
Over priced, too small, heavier and isn't folding. This didn't need any crowdfunding
HUGELY overpriced for what it is.
that doesnt look very parabolic
It’s just a small section of an enormously huge parabola
