END FED 5B short mk1Code: 286/CU- 286/CU-2 Choose variant
Product detailed description
Wire HF antenna with a radiator fed at the end.
The antenna is fed by a 50 ohm coaxial cable.
mk1 version - mechanical version for suspension mounting
The radiator is single, end-fed and electrically designed in ½ lambda length or multiples thereof.
It connects to the transformer circuit.
The usable bands are according to the selected emitter.

The antenna should be complemented with a Link Insulator, connected as close as possible to the antenna.
This will prevent shell currents and interference (RFI).
Depending on the specific mounting design, the use of an antenna tuner on some bands should be considered. The quality of the ground, surrounding objects and environment, the height of the ends of the radiator, the shape of the radiator extension (horizontal, angled, cranked, etc.) have an influence.
Optimal mounting conditions are: horizontal at 10m height, power supply with a coaxial cable of the length of the impedance repeater to the lowest band used. Impedance repeater = ½ lambda x truncation factor (for the specific cable used)
