End Fed Half Wave Antenna-11 Bands One Antenna

If you can't see the video, please insert this title URL into your browser search box: https://www.youtube.com/watch?v=Ree8NtpEEW4.  This is post 2151 in a continuing series of simple ham radio antennas.

In this intriguing video from Steve Ellington, we learn how to build a super antenna covering 11 amateur/ham radio bands.  Although this antenna is a bit more complex than your average dipole or 1/4 wavelength vertical, most radio amateurs should be able to build this versatile antenna with a little patience and creativity.

Steve explains how he created this antenna:

"What started out as an 8 band antenna now covers 11 bands. The EFHW transformer can be bypassed with this relay which turns the antenna into a 130' end fed. It now resonates on 160, 60 and 6 meters when in the bypassed position. If the 160m antenna appears to be too long, insert a series capacitor in the antenna lead between the boxes. I found that I needed .0015uf. Voltage rating needs to be at least 1 kv for higher power. You can install the capacitor externally or internally.
