9:1 Impedance Transformer
a 9:1 unbalanced to unbalanced UNUN impedance transformer, is to experiment with an Inverted V end fed antenna for 80 to 17m, I'm not aiming for transmission on 12 and 10m

A simple broadband 4:1 Balun Transformer
10 bifilar turns are mount on an Amidon FT-240-61 ferrite core
Balun 4:1 Para varios tipos de antenas
The balun performs this function! that is, it overcomes this inequality and improves signal transfer
UN-UN for longwire antenna
The photo above shows the winding of about 70 turns and of 0.5 mm covered wire
The Dual-Ferrite-Bead 4:1 HF Balun
Ruthroff voltage balun design using a T200-2 Toroid core was selected
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
