The End Fed Half Wave (EFHW) Antenna

I have been doing some research on the EFHW antenna and I am finding some things about it that I like. I found a 10pF-310pF variable capacitor that I had bought for my magloop experiments but could only handle about 650V. This turns out to be perfect for an EFHW matchbox. I am looking into how to wind a suitable transformer for this. The advantage is an EFHW antenna is resonant on the band of interest and does not require a tuner. I’ll post more on this as I work out the design.
