KV130

1/9

The KV130 is a rugged bidirectional rigid dipole antenna for the 30 meter band with a total length of 10.20m and uses high Q coils.

Although many people don't know, a rigid dipole antenna has a gain of 2.14 dBi, but can reach more than 6 dBi due to the positive interaction with the ground, as we can see in the radiation diagram simulated by software.

There are several advantages to using a rigid dipole instead of a wire dipole, such as having a bidirectional rotating dipole, installing in a horizontal position to obtain a uniform radiation pattern, keeping the ends of the antenna away from the ground, objects and structures, reducing noise pickup, etc.

COILS:

The calculation and construction of the coils was one of the main points of attention in the antenna design, since it is only possible to obtain a high-performance shortened antenna with well-constructed coils and quality wires. In our antennas, we use enameled wire with a gauge of 8.4 mm² and a good ratio between length and diameter of the coils. These characteristics allow the coils to present very low losses and support high power. In addition, the coils were calculated to dispense with the use of "capacitive radials", which facilitates assembly and installation.
