Overview

DX Engineering Pretuned Quarter-Wave Phased Array Cables

DX Engineering Pretuned Quarter-Wave Phased Array Cables are ready to go into your phased array for 80 or 40 meters. These RG-11U coaxial cable assemblies are electronically tuned during production to 3650 kHz and 7100 kHz, the two most popular phased array frequencies. Pretuned Quarter-Wave Phased Array Cables ensure optimum pattern control and gain from your phased antenna array. They are available individually, in pairs and in four-packs, all terminated with soldered silver-plated PL-259s. These cable assemblies are exactly as required for many 80 and 40 meters phased arrays including Comtek Hybrid Four Square Arrays, DX Engineering TFS4 Four Square Arrays, as well as DX Engineering Dual Vertical Arrays.

DX Engineering Pretuned Quarter-Wave Phased Array Cables are made from the highest quality waterproof PE jacketed, direct-burial RG-11/U 75-ohm low-loss foam coaxial cable. They are called "phasing feed-lines" because they are one quarter wavelength long electrically, which differs from the free-space dimension by the velocity factor of the cable. This RG-11U coaxial cable is manufactured to DX Engineering specifications, with a nominal velocity factor of 0.82. That means they're the right physical length to allow for easy burial and routing from the center-mounted array phasing unit to the base of each vertical element.

Maximum performance is achieve with properly installed phased arrays, including ground-mounted base-fed full-size quarter-wave elements with free-space array dimensions and complete, interconnected ground radial wire systems. The electrical dimensions of phased array transmission cables are critical to system performance. Each of our cable assemblies is hand crafted and electronically tuned at DX Engineering. Eliminate the trouble and concern of trying to tune your own cables and order a set of DX Engineering Pretuned Quarter-Wave Phased Array Cables.

NOTE: Custom tuned phased cables for all other frequencies in each Amateur band are also available. See DX Engineering Phased Array Quarter Wave Tuned Cables.
