DX Engineering RT4500HD Rotator Control Extension Cables
DX Engineering RT4500HD Rotator Control Extension Cables are premium pre-assembled cables with the appropriate 4-pin mating connectors installed for the DX Engineering RT4500HD Rotator. They eliminate the time-consuming task of soldering two additional optional connectors onto a long control cable. Designed for durability, these 4-conductor cable assemblies are rugged, yet flexible and are built to last with heavy duty stranded copper conductors and industry leading direct-bury polyethylene (PE) black jacket that is impervious to water and highly resistant to sunlight UV. Two 12AWG wires are for DC supply to the rotator motor and two 18AWG wires are for the rotator Pulse Sensor. One end of the cable features an interlocking weather-sealed 4-pin DXE-LP20-F female connector that mates with the RT4500HD rotator pigtail male connector. The 4-pin DXE-LP20-M cable mount male connector on the opposite end of this extension cable is intended to be connected to the controller pigtail. The DXE-LP20-F Rotator Control Line cable-mount female connector supplied with the RT4500HD, along with any convenient length of DXE-CW1812OR Heavy-Duty Spec Rotator Cable (sold separately), can be used to make a permanent pigtail with appropriate ring terminals for the screw terminal connections on the rotator controller. The use of the pigtail and this Rotator Control Extension Cable with mating connectors supports easy disconnection of the controller for additional surge protection and for simplified equipment repositioning. In this arrangement, the female receptacle connectors are appropriately used to supply power. Cable mounted male connector exposed pins are never energized when they are disconnected from their mate, thereby eliminating an accidental short circuit to ground. NOTE: At the appropriate point along the run, this cable may be cut, split, prepared and terminated for connection to a grounded surge protection device. Control Line Surge Protection, such as the DXE-CLTB-M or DXE-IS-RCT, is recommended to be installed at the grounding point of the tower base.

DX Engineering Phased Array Quarter Wave Tuned Cables
DX Engineering Phased Array Quarter Wave Tuned Cables ensure optimum pattern control and gain from your phased antenna system. These cables are custom built to your array frequency, made with the highest quality waterproof PE jacketed, direct-burial RG-11/U 75-ohm low-loss foam coaxial cable and terminated with silver plated PL-259s. From the system phasing unit to each array element, these phasing feed-lines are one quarter wavelength long electrically, which differs from the free-space dimension by the velocity factor of the cable. The electrical dimensions of these cables are critical to system performance. These cables, manufactured to DX Engineering specifications, have a nominal velocity factor of 0.82, providing plenty of physical length for easy burial and routing from the base of the vertical to the center-mounted controller. DX Engineering Phased Array Quarter Wave Tuned Cables are custom built by DX Engineering. Each is hand crafted and electronically tuned to a specific HF frequency. Typically, they are tuned to the same frequency as the antenna array. After placing your order for DX Engineering Phased Array Quarter Wave Tuned Cables, please inform us of the order number and your array frequency for your tuned cables by e-mailing dxengineering@dxengineering.com or by calling 800-777-0703 or 330-572-3200. You may leave a message after business hours. Custom cable assembly orders will process after we receive your frequency information. Please contact DX Engineering Technical Support if additional assistance is needed. We will contact you if we have any questions about your special order.
