The Delta7B antenna is engineered to operate across seven frequency bands, ranging from 30 to 6 meters, delivering commendable performance. This multiband antenna is designed to use an automatic tuner (ATU) for most bands. However, it achieves an acceptable Standing Wave Ratio (SWR) on both the 20-meter and 10-meter bands without the need for a tuner. The Delta7B's omnidirectional design ensures a low elevation angle, akin to vertical antennas, while maintaining low noise levels similar to loop antennas, making it an excellent choice for various amateur radio applications.

For operators requiring higher power output, the Delta7B is also available in a variant known as the DELTA7B3, which supports a maximum transmit power of 3000 Watts through a robust balun. This feature caters to users who may find the standard 1000-watt capacity insufficient for their specific needs. The antenna's construction includes a pole clamp, essential tools, and a manual, ensuring users have everything necessary for installation and operation.

Technical specifications highlight the Delta7B's weight at 9 kg and a wind surface area of 0.26 m², with a maximum wind speed tolerance of 120 km/h. It supports a 50-ohm impedance and exhibits impressive gain values across various frequencies, including 8 dBi at 14 MHz and 9.19 dBi at 50 MHz. With a rotation radius of 2.85 meters and a single SO-239 connector, the Delta7B is a versatile and efficient solution for amateur radio enthusiasts seeking reliable performance across multiple bands.
