Why is it showing a Short Circuit. 49:1 Transformer EFHW Well that's because it is. Let me explain, if you use a multi-tester to check continuity it will sho...
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...
It looks like you have 6 turns on one side and eight on the other. Still 14 turns, but I have built mine with 7 and 7. A turn is considered a pass through the inside of the toroid. Also check out some of Steve Ellington’s videos on 49:1 transformers on YouTube.
Just been re-watching this video and noticed a mistake the correct value for the capacitor should be 100pF not 100uF.You can support this channel financially...
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.
4 sie 2020 · This is the page on the End-Fed Half-Wave antenna with a 49:1 transformer. This is a multiband antenna without the need for any tuner (which is the best type of antenna).
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.
