This is a followup video to #344 where I assembled the 49:1 UNUN kit from HF-Kits / ARRL. Here I show finalizing the antenna, getting it in the air, and run...
14 cze 2022 · My 49:1 UNUN now rated at 100 WATTS. @TheArtofEngineering. In this video I show how I made an UNUN for my EFHW inverted V antenna. I use it to replace my QRP UNUN so I can CRANK my...
Just a quick video showing how you can test your EFHW 49:1 UnUn for Impedance Matching / Transformation. In this video, we use a RigExpert AA-30.ZERO Antenn...
1 lut 2020 · The End Fed Half Wave is the most built antenna based on the #ELKPAK. Discover how Frederic, F4IHD, built his own portable #EFHW with the Elektro Ludikits "Portable Antenna Kit" and the 49:1 UNUN option...
The 49:1 impedance transformer ( or 64:1 ) will help you bring down the high impedance of your resonant EFHW antenna to almost 50 Ohm. Let’s have a look at a few details on how to build a 49:1, or a 64:1 impedance transformer.
7 lut 2024 · Along my journey on understanding radio, electronics, and in particular, the magic of baluns, ununs, and other transformers, I came across this helpful video on how to analyze a 49:1 unun with a NanoVNA. I replicated it with the the “Alleyway Antenna” transformer.
22 lut 2021 · The following is a list of materials required to make a 49:1 unun impedance transformer for an end-fed half wave antenna. You will also need a half-wavelength length of wire (14 or 12 gauge typically) in order to construct an antenna radiator for whichever ham band you choose.
