QRPGuys Portable No Tune End Fed Half Wave Antenna
Single band, 80m-10m end fed half wave wire antenna. It is designed as a highly portable wire antenna, easily set up as an inverted V, horizontal, sloper, or in the case of higher frequencies, a vertical radiator. Your feed line is essentially the counterpoise, so a separate one is not needed. The high impedance, half wave wire is matched to your 50 ohm feed point by an integral impedance matching toroid transformer, and rated is at 10 watts

160m mini portable End Fed Half Wave Tuner
The setup for 160m and 40m using an end fed half wave tuner and a kite is simple and easy to setup
160 meter end fed
With this length of wire a coil of 11 turns is required, resonating the antenna on 1.950MHz with an SWR of 1.5:1
40m End Fed Half Wave EFHW Antenna
The feed point of the EFHW is in the order of 3000 to 5000 ohms while the 1/2 wave dipole will be closer to 50 ohms in the inverted V configuration
