웹Attenzione ,sto facendo proprio in questi giorni dei test sui balun ; mi serviva un balun 1 a 2 ; bene. Quello che proprio NON BISOGNA FARE E' USARE UN TOROIDE T200 e NEANCHE QUELLO GIALLO . Per costruire un balun che funzioni discretamente da 1 a 30 mHz serve un toroide con u (permeabilità) di 1000 circa ; il T200 ha un u di 10 , quindi non va bene .Va … 웹In our example, the SWR on the transmission line is 5:1. This is equal to the ratio of the antenna impedance (10 ohms) to the transmission line characteristic impedance (50 ohms). Thus, without knowing anything else, we know that the maximum voltage along the line is 5 times the minimum voltage. And we also know that the maximum current on the ... 웹2011년 7월 2일 · It does not. work. 2.5+ SWR on 10 meters with a 200 ohm resistor plugged up to the. terminals.

웹2024년 10월 3일 · I Balun, cosi’ come pure gli UnUn, effettuano anche una trasformazione di impedenza tra una porta e l’altra (ad es.: 1:1 , 2:1, 4:1, 9:1 , etc.) ESEMPI DI VOLTAGE … 웹For example, if you have a 4:1, then the device has a high impedance that’s four times balanced to unbalanced impedance. The goal of the device is to lower the input impedance and maintain the output impedance. Baluns usually come in 4:1, 6:1, and 9:1, but individuals can experiment with the frequencies they’re looking to emit.
