There are many different designs and you may even have some luck with a good old fashioned 2m ham radio antenna. This ideally should be a circular polarized one. This seems to work by far the best for me. The one I used is pictured below and I use this in conjunction with a Signalink USB Soundcard I had laying around. It WILL give you better images if you do compensate for this obviously, but not needed.

The dedicated receiver will take care of the doppler issues as will some plugins with some of the SDR software if you are concerned about this. If you are not compensating for doppler effect the receiver bandwidth should be set to 50 kHz or so to receive all the data of the modulated signal. The signal is 30+ kHz wide signal which prevents narrow FM modulation receivers from being used. Note that Scanners and the ham radios may have bandwidth issues. I have used ALL of the above at some point and had pretty good luck with all the AirSpy and even better with the HackRF One or the dedicated receiver below I own WeSatCom APT-06 from Germany were tied for first place. You can look at the photos of the inside of this unit as well as some other similar units on my PiAware ADS-B pages of this website. This unit is easy to find, including one here on Amazon. Needless to say the NOAA APT satellites orbit (move around the earth) and they pass a few times overhead at each location on earth, generally twice a day but at times more passes can be captured. If you are interested in building a receiver for these, please visit the Setting up a GOES Geosynchronous Weather Satellite Receiver using a Raspberry Pi page on this website. GOES satellites are very directional and use 1.6941GHz. GOES-13 (2006) 75° W “East coast view” - Not Active.Geostationary Orbiting Environmental Satellites (GOES) Weather Satellites are: The latter is perhaps a different article as I would not recommend starting with those. As well as some geostationary satellites. The newer Meteor line of satellites (M2 specifically) from Russia, which provides much higher resolution. There are the ones I will be focusing on above. The NOAA-19 APT image resolution is 4-km (2.5-mi). I should start out by saying that there are many ways to go about doing this.
