Recently I got an interest to experiment with NOAA weather satellite reception techniques. As a first thing, I did search on the internet for a suitable antenna for NOAA satellite frequencies (137.100 MHz - 137.9125 MHz). After examining a couple of designs, I decided to build a Turnstile antenna which is designed by Ivo Brugnera I6IBE . Due to the COVID19 lock-down, I build this antenna using parts that are already available in my inventory. Originally, I build this antenna on a wood-stick, and later I changed it to a stable setup as shown below. Assembled antenna for 137 MHz NOAA weather satellite receptions. Following materials and components are used for the above construction: - Two 8cm × 8cm × 6cm waterproof ABS project box. - 54cm long, ⌀ 21mm PVC tube, which is reinforced by inserting water resistivity wood stick. - 8mm thread roads. - M8 nuts and M8 flat washers. - 50Ω and 75Ω coaxial cables. - PL259 male and female connectors. Before constructing this ant...
