KV2040-DX
YAGI-UDA DIRECTIONAL ANTENNA 4 ELEMENTS DUAL BAND 40 AND 20 METERS




The KV2040-DX is a 4-element dual-band Yagi-Uda directional antenna, 40/20 meters, which in practice are two monoband antennas sharing the same boom, each with its own independent power supply. A way to optimize space and obtain high performance on the 40 and 20 meter bands, whether for local QSO, DX, Contest, digital modes, etc.
For those who already have the KV240, there is the option of purchasing the transformation kit to add the 20 meter band.
For the 40 meter band there are two 70% size elements with high Q coils, while for the 20 meter band there are two full size elements without shortening. Both elements are mounted on a 6.0m boom making the KV2040-DX a unique antenna on the market.
The KV2040-DX is ideal for forming a combo with the KV1015-DX, a KV ANTENAS solution for 10, 15, 20 and 40m bands in the same setup.
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-built coils and quality wires. In our antennas, we use enameled wire with a gauge of 8mm² and a good ratio between the 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.
