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
