Balun Test
Many articles and technical sources on baluns or balun design ignore voltage, focusing only on current. Focusing only on current is a serious oversight that can result in defective system design

1:1 Balun for HF wire
1:1 50 ohm balun for use on HF horizontal wire dipoles. It uses an AM radio ferrite rod, with 3x14 turns of wire. 10-14 turns should be good for 2-30MHz. 18SWG enammeled copper wire
Binocular ferrite 9:1 balun RX Transformer
There are lots of good designs for matching transformers for receiving antennas. it's cheap and easy, and very high performance
1:9 Antenna balun
I had this feeling the 1:4 balun was not presenting the greatest match to the open feed line. After I built and tried this 1:9 balun the autotune antenna tuner was able to
1:9 Antenna Long Wire con Balun 9:1
Vi occorre un antenna semplice e di sicuro funzionamento, in pochi minuti potrete costruirvi una Long Wire (filo lungo) o corto, fate voi
