EFHW-20/40 - End Fed Half Wave 20m and 40m Antenna
This end fed half wave antenna comes in two parts. The 10/20m end fed feedpoint with 33' of wire and the add-on extension wire that gives you 40m as well. The 40m wire is a little longer than necessary so you can cut it to be resonant for your particular field operation setup.
This 20/40 model also includes a 33' antenna wire finished off with strain loops and gold banana connectors. To add 40m just plug in the additional wire and connect the strain relief loops to the supplied plastic clip.
If you want to operate on 60m or 80m, you will want to add additional wire. You can either extend the existing wire with connectors and clips like our linked dipole or you can add your own wire to the feed point body. We provide a spare female banana socket for an add-on wire or you can de-solder the wire supplied and replace it with your own wire.
With the 40m add-on wire you can also work 15m. The antenna is usually has very low SWR on all bands. 15m will be slightly elevated but will work fine.
