Description

10/(15)/20/40 End fed antenna kit, including 100 Watt 1:49 Impedance transformer, wire of your choice, DIY kit

An advantage of an end-fed antenna is of course the simplicity. The fact that the antenna has no feed point in the middle makes placing the antenna very easy. Due to the solid tensile stools, this antenna can be used in permanent setups. The 10/(15)/20/40 End fed Antenna Kit has a total length of approx. 20 meters. On the 10, 20 and 40 meter band the antenna can be work without an antenna tuner. An antenna tuner is required for the 15 meter band. The feed point of the 10/(15)/20/40 end fed Antenna kit is a broadband impedance transformer. This means that the end fed wire antenna with a very high impedance +/-2500 Ohms is transformed to an impedance of 50 Ohms.

This 10/(15)/20/40 End fed antenna kit comes with antenna wire of your choice:

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 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.

Copper/Stainless Wire: This antenna Wire is produced especially for HF Kits in the Netherlands. The wire consists of a stainless steel core (7x 0, 35mm) with around 1.0 mm2 tinned copper braid. 7x 0.3 mm stainless steel and 14x 0.3 mm thinned copper. The insulator consists of black UV resistant PE. The total diameter is about 2.5 mm. Tension force approx. 100 kg. This is a robust antenna wire with a very long life span. As far as we are concerned, this is the best choice for permanently placed antennas.

Tips:

  • As much as possible, Hang the antenna free from interfering elements
  • This antenna can also be used as a sloper.
  • If you can’t get rid of the entire length, zigzag also works, avoid angles sharper than 90 degrees.
  • In case of common mode issues, use a common mode choke. Do not place this choke directly at the feed point of the antenna.
