Through out my nearly four decades of Ham Radio, I have never used an End Fed Half Wave Antenna. As it is difficult to route multiple coaxial cables into my shack, I thought that Multi-Band EFHW is the only way to go for multiple bands. I been using a modified inverted V antenna for 40 m and an inverted V dipole antenna for 20 m for the past two months or so. Though I had used a dual band fan dipole for 40 and 20 m in between, I was not very happy with it. Bought an EFHW for 40, 20, 15 and 10 m from another ham. The antenna length was mentioned as 20 m, which was half wave at the lowest frequency. It would resonate for higher harmonic ham bands without an antenna tuner.
