Just look at those specs below. This is truly the last remote coax switch you will ever need. Look at how clean both the outside switch box and control boxes are. See pictures, you get the RR8A-HP external switchbox and CC-8A in-shack controller as shown. This is BETTER THAN NEW. Because the performance is the exact same – just cheaper!

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. Features include: Fully RF shielded with stainless steel mounting bracket and hardware Best port-to-port isolation available: >70 dB below 30 MHz, >60 dB below 60 MHz, >45 dB below 150 MHz Loss.
