MCIR false color enhancement with normal projection. Captured from NOAA 18 on 26th April 2020 at 08:35:18 IST.

Sri Lanka, the Bay of Bengal, and Andaman sea. Captured from NOAA 15 on 25th April 2020 at 19:45:16 IST. Some of the satellite images which I processed with this setup are illustrated below: I test this antenna with all the NOAA passes, and every time I manage to get an excellent signal from the satellite.

Channel B is the thermal infrared view.Īt the testing stages, I manage to receive APT transmissions from all the active NOAA satellites such as NOAA 15, NOAA 18, and NOAA 19. This image is captured from NOAA 18 and processed with noaa-apt. After examining and comparing the features provided by the above packages I decided to stick with WXtoImg to process my APT streams. I examine a couple of APT decoders with my setup which including WXtoImg, APTDecoder, and noaa-apt. To get the APT transmissions I setup SDRSharp with following parameters: RTL R820T2 SDR is used to test the constructed antenna. Wiring layout from dipole elements to PL259 connector. The antenna is installed 13m above the ground, which is nearly 48m from the sea level.

The modified design is transferred to CAD drawing and available to download at the locations given at the end of this post. 54cm long, ⌀ 21mm PVC tube, which is reinforced by inserting water resistivity wood stick.īefore constructing this antenna, I did some minor adjustments to the design by changing element spacings and lengths. Two 8cm × 8cm × 6cm waterproof ABS project box. Originally, I build this antenna on a wood-stick, and later I changed it to a stable setup as shown below.Īssembled antenna for 137 MHz NOAA weather satellite receptions.įollowing materials and components are used for the above construction: After examining a couple of designs, I decided to build a Turnstile antenna which is designed by Ivo Brugnera I6IBE.ĭue to the COVID19 lock-down, I build this antenna using parts that are already available in my inventory. As a first thing, I did search on the internet for a suitable antenna for NOAA satellite frequencies (137.100 MHz - 137.9125 MHz). Recently I got an interest to experiment with NOAA weather satellite reception techniques.
