Overview

DX Engineering KX4O Vertical Dipole Antenna Support Plates

KX4O Vertical Dipole Antenna Support Plates are used in the construction of John Huggins' version of an increasingly popular portable HF antenna. It is called an "Asymmetrical Hatted Vertical Dipole," but John shortened the name of his version to "AHVD". It uses mostly off-the-shelf DX Engineering hardware to construct a very robust and versatile portable antenna.

His approach is basically a tripod-mounted vertical dipole radiator with an inverted "hat" that serves as an asymmetrical counterpoise. It's an upside-down "T" in appearance! Assembled largely from telescoping aluminum tubes, the antenna elements may have their length easily changed to allow for single-band resonant-coverage from 20 through 10-meters. Due to the relatively large-diameter but lightweight aluminum tubing and electrical design of the antenna, bandwidth is very wide.

At the center of John's version of the AHVD are two important items--the support plate and a 1 ft. long slit aluminum tube. DX Engineering is pleased to offer the pre-drilled support plate and the aluminum tube that are at the heart of the antenna!

Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information.

When you consider building a five-band 20 through 10-meter HF portable antenna, give the KX4O version of the Asymmetrical Hatted Vertical Dipole a try. An engineering drawing, design discussion, and list of materials are available on the KX4O website. These KX4O Vertical Dipole Antenna Support Plates, as well as many other parts for this antenna, are now available from DX Engineering!
