Balun circuito Balanced
The word balun is a contraction of BALanced to UNbalanced transformer, that is, balanced to unbalanced transformer. So the best thing to do is to start by understanding what exactly this concept of balance refers to

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

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
30 Volt Computer Power Supply Stack A bonus was that i discovered that these did not need a standby load connected to the supply to keep them running just apply mains power and close the Start lead to ground
