EndFed 12-30 100W Warc band

The Momobeam EF1230-100W warc band is a multi-band wire antenna that covers the amateur radio frequencies 10, 18, 24 MHz!
It can be installed in a few minutes either horizontally, inverted L or sloper!
Its features make it perfect for a fixed installation and for your portable activities.
All the bolts are made of stainless steel while the box and wire are made of materials resistant to ultraviolet rays.

In the past the “end fed” antenna was very popular among radio amateurs.

One of the first examples was the Zepp antenna which was originally used on Zeppelin airships during the First World War!
The main characteristic of the End Fed type antenna, as the name suggests, is that it is fed at one end, a point where the impedance is very high (around 2500/5000 Ohm).
The main advantage of these antennas is that by using a long half-wave radiator, it will also have a high feed point impedance at higher harmonic frequencies therefore by using an appropriate impedance transformer, our antenna will be able to operate on multiple bands with a acceptable mismatch.
The main components of our “end fed” are the radiating element composed of coated copper core wire and a wide-band impedance transformer with a ratio of 49:1 which has the purpose of converting the impedance of the feed point raised to a value closer to 50 ohms.
