END FED 5B short mk2Code: 295/CU 295/CU2 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.
The transformer circuit is mechanically designed to allow high variability in different mounting conditions.
mk2 version - movable massive radiator mount
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.
4B short - 7-14-21-28 MHz - emitter length 12,5 m, includes coil
4B - 7-14-21-28 MHz - emitter length 20 m, does not include coil
5B short - 3,5-7-14-21-28 MHz - emitter length 24 m, includes coil
5B - 3,5-7-14-21-28 MHz, emitter length 42 m
- 3.5-28 MHz bands
- emitter length 24 m
- coil included
- antenna cable according to the selected variant
- unun END FED
- power load 300 W PEP max (on digi, FT8 etc. max 100 W)
- weight 1 kg
- the mounting is variable thanks to the mechanical design of the Unun
- PL connector (UHF)
- stainless steel fasteners
The transformer circuit can be mounted variably in different placement conditions - using plastic or metal pull-tabs on a pipe, railing, mast, etc., it can just be hung or screwed to a surface.
The antenna should be supplemented with a Link Ibsuolator, 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)
