Programs for balun
Baluns are very complicated with poor designs giving very poor results. If you have some knowledge, this program will assist you in designing rf transformers and antenna baluns and unun

Balun 1:4 UNBAL to BAL
if you want to use the balun in the QRPproject format, prepar e the enclosure and solder the UNBAL part as short as possible to the BNC connector
Original cushcraft balun
So the results I found on the Cushcraft balun are better than I expected, therefore I will use the balun like it is
Wind Your Own RF Matching/Isolation Transformer
It's the question I'm asked most often about broadband loop antennas such as the Delta, Flag, and SuperLoop Where can I find the matching transformer?
Conversion CB antenna balun for HF Antenna
The UNUN balun because no equilibrium is reached, I experimented with the base material FT 140-43 and obtained partially better resul

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
Interface-for-digital-broadcasts-with-integrated-audio 4-port HUB, with a TUSB2046. With port 1 of the HUB we drive the FT232RL; with port 2 the PCM2904, furthermore, we decided to leave ports 3 and 4 free
