how to receive WEATHER satellite image From NOAA satellites and RTL-SDR vlog v3

Antenna design 3-elements UDA YAGI antenna --------------------------------------------------- Frequency f: 137 MHz Wavelength λ: 2 m 188 mm Element diameter: 7.3 mm…21.9 mm ( min.: 0.003λ , max.: 0.01λ ) Approx. antenna gain: 7.3 dBi Bandwidth by VSWR less than 2: 10 MHz (approx.) --------------------------------------------------- Reflector length R: 1 m 130 mm --------------------------------------------------- Dipole length V: 1 m 24 mm Dipole-reflector distance S1: 376 mm --------------------------------- Director length D: 930 mm Dipole-director distance S2: 300 mm --------------------------------------------------- Minimum boom length Bl: 698 mm here element dia is given as 7.3 mm, but if we reduce it to 5mm, the bandwidth will be narrow. Tht doesn't hurt us as we are only using the center freq for antenna calculation and we are not transmitting. The BW may swing on either side by 100 khz For decoding software i have used "SatDump" on my windows 11 PC I hope you guys enjoyed the video...if you wanna know something about the video or in general, comment down 👇 , most of the time I have nothing to do...so we can chat 🙂
