End Fed Half Wave (EFHW) Experiments | Ham Radio

In this Live Stream we will look at: ° Various EFHW transformer variants i built in the last three years ° How to use SimNEC and a NanoVNA to compare different variants ° New torroids to try out for better efficiency (Fair-Rite 2643625002 and 2643251001) ° Websites from other OMs about EFHW Antennas / Transformers to check out Edit: I just realized I consequently used the wrong unit when talking about the compensation capacitors. Even in the names of my saved SWR curves 🤦‍♂️. Of course the unit is Picofarad not Nanofarad! So 100pF is the “standard“ value. Sorry for that! I’ll go and rename about 100 files now. 😣 Intro Music: Peter W - Spy vs Spy (Instrumental Version) Links: K1RF PD7MAA Owen Duffy ht
