I got one second hand for 10€, I modified the dipole for 1.7 GHz, I was able to receive GOES 16 from Portugal at 8.8º elevation

Damn I'm also at Portugal, but I don't want to disassemble the antenna bc I want to use it for S Band also

@@twitch_theoxidado9043 You can always make 1.7 dipole from scratch and make a new shell for it if you have a 3D printer.

Great video! I keep meaning to try one of these!

Awesome! I just got mine a few days ago, going to point it at GOES-16 and try and get some photos of the eclipse on the earth.

Haven't started watching video yet, but with that title im sure this will be amazing

The general rule is the holes have to be equal or less than one-tenth of the operating wavelength.

Good idea. I've few those antennas in my garage but I live in Poland so I don't have a signal from GOES satelites. Those feedhornes can be use for receive LTE signal on 2600MHz, it works very well out of the normal band :)

have you considered building a antenna rotor controller, with a light antenna that also has minimal wind loading it should be easier to use relatively low cost components to get a pretty stable tracking mechanism

Great video, I have 2 of these. Only problem I have with it is I get Sample dropouts. It does work for HRPT and GOES 16

@dereksgc 4 ай бұрын

You might want to try adjusting your sample rate, on the RTL-SDR ADC sometimes it can help reducing to 2.4 Msps

@albatross_v2 4 ай бұрын

Are you using Windows? Windows is known to cause sample drops, if possible try using Linux.

@@albatross_v2 Yes I'm using Windows 10 Pro on my Laptop, I have great signal it's around 14 snr at times I do see the waterfall hope not sure if that's caused by the Cell tower that's nearby.

I actually had almost the same one but smaller in Poland for my first network access when i was 7

I wonder if a Lora Meshtastic is already being beamed to pirate 🏴‍☠️ satcom and would be interesting to listen to them for any Lora transmissions. Of course it’s 800 to 900 megahertz but I wonder if someone has used a translator to use it as a space repeater and then I wonder about the other satellites being used for Lora packets only because ham operators always think they have a license to “ experiment “

Did you manage to 3D print a useable mount ?

Replace the dipole with a yagi. Are you using a SAW filter + LNA?

Do you think that the WiFi grid antenna can access GOES Sat from London UK?

@dereksgc 2 ай бұрын

Check with an app like look4sat or gpredict to see if you have line of sight, you need a clear view of the satellite with no obstructions. I don't think the 2.4 GHz grid antenna would work on its own, you would probably have to modify it so its properly tuned at 1.7 GHz

Have you tried using a helix feed for the circular polarized sattelite?

How would this work against Himawari8?

@dereksgc 3 ай бұрын

as far as I know, neither of the Himawari satellites transmit anything in the 1.7 GHz band, it would most likely work very well for the GK-2A satellites and the Elektro-L satellites if you do get a better line of sight than me, the performance can be improved by rebuilding the dipole, something I'm currently making a video on
