Introduction The DX Engineering 2-Port Receiving Antenna Switch RLS-2 is designed to allow selection of one of two output ports (generally connected to different receiving antennas) from one feedline. Transfer activates with application of a +10-15 Vdc or 9-12 Vac control voltage through the feedline.

Installation The RLS-2 can be placed at any point between the operating position and the antenna, although it is typically installed near the antenna systems. Any location with ambient temperatures below 150° F (65° C) is acceptable. In outdoor applications, a bead of non-corrosive, marine grade silicone, like DX Engineering part number DXE-RTV598335, should be used along the seams of the enclosure. Be sure to leave a small opening in the bead, at the lowest point, for a condensation drain.
DXE-FVC-1 - Feedpoint Voltage Coupler The FVC-1 provides an interface for standard control switches, such as the DXE-CC-8A or your own arrangement to voltagemultiplexed antenna systems. This interface system will provide the voltages required to remotely select up to four antennas (or four directions) through receiving or low power transmitting feedlines. It provides fuse-protected 0V, +12 Vdc, -12 Vdc, and 12 Vac. output voltages through a panel mounted feedline connector.
DXE-RPA-1 - Receiver Preamplifier, 0.3-35 MHz This is the best HF low noise amplifier available. The RPA-1 is optimized for 0.3-35 MHz operating range. The push-pull amplifier design and robust components enable it to withstand high signal levels and operate when you need it most. The dynamic range of the RPA-1 is better than most receivers. The RPA-1 is suitable for indoor or outdoor installation, with the option of being powered through the coaxial feed.
DXE-CW9-1K - Shielded Control Wire, 9 conductor, 1000 ft reel DXE-CW9 - Shielded Control Wire, 9 conductor, per foot DXE-CW9-1K is a 1000 foot box of high quality shielded outdoor FTP (Foil Twisted Pair) Cat5e cable. It features 4 Twisted pairs of 24 AWG solid wire with Al foil shielding plus a solid tinned copper drain wire - providing a total of 9 conductors for DC switching applications. It has a polyethylene jacket and is rated for direct burial.
