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.
