The antenna employs a pair of turnstile radiators, a 1:2 power divider and a 90° phase shifter. After a series of simulations and optimizations, the maximum circularly polarized gain at 39 MHz is 5.9 dBic with 96° 3 dB beam width. The simulated axial … 웹2024년 2월 28일 · This is how 4:1 and 9:1 current baluns are constructed, such as the 4:1 unit below which is constructed from a pair of 1:1 current baluns. Coaxial cables longer than 1/8-wavelength or so can also be used to create transmission line impedance transformers. refinery fire watch
