DBZ017 Double Bazooka HF Dipole Antenna 17 meters - Frequency 18 Mhz.
The Double Bazooka antenna concept is interesting and useful for radio amateurs who want to operate in a wider frequency range without the need for a tuner.
The DBZ017 Antenna Dipole Double Bazooka for the 17 meter band is specifically designed to operate on the 18 MHz frequency. This frequency falls within the 17 meter band in amateur radio, which extends from approximately 18.068 MHz to 18.168 MHz. The DBZ017 is an efficient antenna tuned to operate in the upper part of the 17 meter band, making it ideal for amateur radio communications on this specific frequency.
Improved SWR across a Frequency Range: Unlike a classic dipole, the Double Bazooka antenna uses a coaxial cable at the feed point to serve as a transformation line. This helps compensate for reactance at the feed point as frequency increases, resulting in a flatter SWR curve over a wider frequency range. This means that the antenna can operate effectively on multiple frequencies without requiring constant adjustments.
Less Need for a Tuner: Due to its greater bandwidth and built-in transformer line, the Double Bazooka antenna can often operate on multiple frequencies without the need for an external tuner. This simplifies setup and reduces the need for adaptive devices.
Robust Construction and Load Capacity: The Double Bazooka antenna is designed to handle higher transmit power levels and its robust construction contributes to its durability.
Low Transformation Line Losses: Although the transformation line introduces slight losses, they are generally so small that they do not significantly affect the performance of the antenna.
The Double Bazooka antenna is an attractive option for radio amateurs who want to operate over a wider frequency range and want a more stable VSWR without the need for a tuner. The combination of its design and construction makes it an effective tool for communication in amateur radio.
