End-Fed Half-Wave Antenna & Tuner
post 17 Aug 2022
I would like to have the option of using the antenna portable, where a transmission line is just something else to carry and end-feeding is probably the easiest to set-up.The final device tunes a resistive load of 3-7 kilo-Ohms from 3.2 MHz to 12.6 MHz. 40 metres is covered (and 30 metres too, but I lack a transceiver for it currently), it is unfortunate that 20 metres could not be covered

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
