웹Confecção de Baluns. Baluns do Tipo-Tensão produzem tensões iguais e opostas a partir do seu terminal balanceado. Considerando-se que as antenas de baixa impedância são alimentadas por corrente e não por tensão, torna-se desejável que o balun apresente correntes iguais e opostas em seu terminal balanceado. Ganha-se muito pouco se ... 웹Current baluns are the balun of choice in all but very specialized situations, because they work better than voltage baluns in most real-world systems. In the case of a 1:1 ratio current balun, core flux density or "magnetizing stress" on the balun core is independent of load impedance or load mismatch. 웹In addition, this model provides both a 49:1 ratio PLUS a 64:1 ratio for those who find their particular installation has a higher feedpoint impedance. Please note that both ratios cannot … dainty perfume
