HY-GAIN's VB-215DX directional antenna is a yagi antenna designed to operate in the 144-146 MHz frequency band, which corresponds to the 2 meter amateur radio band. It has 15 radiating elements, allowing it to direct and focus the signal in a spe more Manufacturer: hygain Reference VB215DX
The Hy-Gain Model 215DX is a high performance yagi antenna for SSB/CW DXing in the 2 meter amateur band. It features 15 elements mounted on a 28-foot (4.03 wavelength) boom, with superior gain, low sidelobes, and a high front-to-rear ratio. It also includes an encapsulated power point and a low-loss, weatherproof N-type connector for use in all types of climates. The usable frequency range of 144-146 MHz makes the 215DX suitable for 144 MHz EME and terrestrial DX, as well as 144-146 MHz satellite communications. 215DX antennas can be easily installed in stacked configurations to enhance their performance. The design of the 215DX is based on input from the DL6WU log dimmed design. Performance was verified by testing at the range of Hy-Gain antennas and by computer modeling using NEC-2 and Yagi Optimizer(C) computer codes. The antenna's performance characteristics have been optimized for the 144-144.5 MHz frequency range. This electrical design also allows for the addition of more director elements for additional gain, with little or no adjustment required. In other words, it is possible to increase the gain of the antenna by adding more director elements without having to retune the antenna significantly. This offers flexibility and ease in configuring the antenna to suit different conditions and communication requirements.
