COMTEK 40VA 40 Meter Vertical Antennas
COMTEK 40VA Vertical Antennas are rugged, yet economical quarter wave antennas designed primarily to be used in sets with phased vertical array systems. For instance, DX Engineering DVA Dual Vertical Array systems and four square arrays from COMTEK and DX Engineering or any other four-square array controllers. Designed by the people who know all about phasing, these antennas provide precise control of all parameters. Constructed from 6063-T832 (drawn, not extruded) aircraft-spec aluminum tubing, COMTEK 40VA antennas taper from a huge 2 in. O.D. base section to 1-3/8 in. O.D. at the top. While they're built to withstand the most rugged environmental conditions, light guying is always recommended for phased systems to keep the spacing precise and minimize swaying. Hardware used is of the highest quality. High-strength, UV-resistant EXTREN insulators that won't crack, peel, splinter, or fail will ensure you of years of long-lasting, reliable performance under adverse conditions. Mounting brackets are laser-cut by the latest state-of-the-art manufacturing equipment. Stainless steel hardware is used throughout and the antennas come complete with V-saddle clamps for installation to your ground-mounted pipe. A 2 in. O.D. is recommended but the clamps will accept any O.D. from 1 in. to 2 in. Whether you want a quality ground mounted 40 meter vertical as a TX antenna, or are building your dream phased array, These COMTEK 40VA Vertical Antennas from DX Engineering are a great solution!

COMTEK ACB-4 Series Four-Square Switch Relay Units
COMTEK ACB-4 Series Four-Square Switch Relay Units use a well-established design and proven technology to offer any ham an advanced antenna system with s possible. Our phased array systems are affordable, simple to install, and easy to use. COMTEK ACB-4 Hybrid Four-Square Relay Units are single-band phasing and relay devices. They are typically in stock for every major HF contesting Amateur band and 30 meters; 60 meter array units are available by special order. Four-Square arrays are single band specific, due to antenna spacing and phasing feedline lengths, and for proper phasing and patterns. For manual operation, these relay units require the COMTEK ACB-4A Four-Square Control Console. It is now made to run on 12 to 14 Vdc, allowing easy operation of the four square array with battery emergency or International power sources. A DX Engineering factory-tuned cable feed system for the vertical array (available for your center frequency and sold separately) will provide the best performance. The ACB Series Hybrid Switch Relay Units also require a good 50 ohm, non-inductive dummy load. Contact DX Engineering for more information on Four Square Array components.

COMTEK Control Cable
COMTEK Control Cable is a high-quality, PVC-jacketed control cable consisting of either three or four 20 AWG conductors. It may be used in a multitude of control cable applications including remote electronic switching and antenna rotators. These cables are sold by the foot cut-to-length and by 1,000 ft. spool. COM-CW-3 and COM-CW-4 are sometimes thought to be DXE-CW-3 and DXE-CW-4 but they are a COMTEK brand cable.

COMTEK 30VA 30 Meter Vertical Antennas
COMTEK 30VA Vertical Antennas are rugged, yet economical quarter wave antennas designed primarily to be used in sets with phased vertical array systems. For instance, four square arrays from COMTEK and DX Engineering or any other four-square array controllers. Designed by the people who know all about phasing, these antennas provide precise control of all parameters. Constructed from 6063-T832 (drawn, not extruded) aircraft-spec aluminum tubing, COMTEK 30VA antennas taper from a huge 2 in. O.D. base section to 1 1/2 in. OD. at the top. While they're built to withstand the most rugged environmental conditions, light guying is always recommended for phased systems to keep the spacing precise and minimize swaying. High-strength, UV-resistant EXTREN insulators that won't crack, peel, splinter, or fail ensure you of years of long-lasting, reliable performance under adverse conditions. Mounting brackets are laser-cut by the latest state-of-the-art manufacturing equipment. Stainless steel hardware is used throughout and the antennas come complete with V-saddle clamps for installation to your ground-mounted pipe. A 2 in. O.D. is recommended but the clamps will accept any O.D. from 1 in. to 2 in. For 30 meter performance you can count on, order COMTEK 30VA Vertical Antennas from DX Engineering!

COMTEK 20VA 20-10 Meter Vertical Antennas
COMTEK 20VA Vertical Antennas are rugged, yet economical quarter wave antennas designed primarily to be used in sets with phased vertical array systems. They are well suited for Four Square arrays from COMTEK and DX Engineering or any other four-square array systems. These monoband 20VA antennas may be used on any single band from 20 meters through 17, 15, 12, 11 or 10 meters by adjusting the length accordingly. Designed by the people who know all about phasing, these antennas provide precise control of all parameters. These verticals are constructed from 6063-T832 (drawn, not extruded) aircraft-specification aluminum tubing. COMTEK 20VA antennas taper from a large 1.0-in. OD base section to a 3/4-in. OD top section. While they're built to withstand the most rugged environmental conditions, light guying is always recommended for phased systems to keep the spacing precise and minimize swaying. High-strength, UV-resistant EXTREN insulators that won't crack, peel, splinter, or fail will ensure you of years of long-lasting, reliable performance under adverse conditions. Mounting brackets are laser-cut by the latest state-of-the-art manufacturing equipment. Stainless steel hardware is used throughout and the antennas come complete with V-saddle clamps for installation to your ground mounted pipe. Pipe of 2.0-in. OD is recommended but the clamps will accept any OD from 1 in. to 2 in. Plumbing galvanized water pipe called 1-1/2 in. size is actually 1.9 in. OD and works well. For a single 20 meter vertical or a set of elements for a phased array, consider COMTEK 20VA Vertical Antennas from DX Engineering!
