Multiband HF Projects - Longwire Antennas

160–80–40m End Fed Antenna by GØCSK
At the Junction Box , coax inner connects to the antenna wire (blue) and braid connects to the brown wire and ground spike.

The W3EDP end fed wire antenna lends itself readily to QRP and portable operation. A simple matching unit is needed to couple the wire to the rig and a counterpoise is required for some bands, ...
