DX Engineering RR8A-HP Remote Antenna Switches

DX Engineering RR8A-HP remote antenna switches are low-to-medium power RF antenna switches with excellent performance on HF and 6 meters, usable to 150 MHz. They use 16 custom, sealed, moisture-resistant relays to provide the best port-to-port isolation available and reliable, long-term performance. RR8A-HP switches can be used as a conventional one-of-eight antenna switches or configured to simultaneously select multiple output ports, allowing for their use in complex antenna phasing and stacking systems. DX Engineering RR8A-HP switches use a removable screw-terminal control cable plug that greatly simplifies installation by eliminating the need for disassembly or soldering to wire the control lines. The remote relay boxes are custom-made from a stainless steel chassis and a special RF shielded stainless steel cover. There is also a custom conductive gasket to complete the seal between the cover and stainless steel housing base.
