Description
10/20 Mini End fed antenna DIY kit, including 100 Watt 1:49 Impedane transformer
An advantage of an end fed antenna is of course the simplicity, especially for field work this is a huge advantage. The 10/20 Mini Endfed Antenna Kit has a total length of approx. 10 meters. The antenna will work on both bands without antenna tuner.
The feed point of the 10/20 Mini end fed Antenna kit is a broadband impedance transformer. This means that the end fed wire antenna, which has a very high impedance of around 2500 Ohm, is transformed to an impedance of 50 Ohm.

This Mini End Fed Antenna is supplied with your choice of litze.
Experimental Wire: This wire consists of 1.0 mm2 braided copper wire with a UV resistant black shield. The total diameter is about 2 mm. Perfect for experiments or holiday antennas. Because the core only consists of copper, this wire will stretch over time and continue to hang. The tensile force of this wire is thereby also limited.
Copper/Kevlar Wire: This antenna wire is produced especially for HF Kits local in the Netherlands. The wire consists of a Kevlar core with around 1.1 mm2 tinned copper braiding. 1x 0,4 mm Kevlar en 24x 0,25 mm copper. The insulator consists of black UV resistant PE. The total diameter is about 2.5 mm. Tension force approx. 50 kg. In this way a strong, smooth and relatively light antenna wire is obtained.

Tips:
- As much as possible, Hang the antenna free from interfering elements
- This antenna can also be used as a sloper.
- In case of common mode issues, use a common mode choke. Do not place this choke directly at the feed point of the antenna.
