Overview

DX Engineering RR8B-HP Remote Antenna Switches

DX Engineering RR8B-HP Remote Antenna Switches are RF switches designed to have excellent performance on HF through 6 meters.

Using 16 custom, sealed, moisture-resistant relays, these Remote Switches provide the best port-to-port isolation available with reliable, long-term performance. RR8B-HP switches may be used as conventional one-of-eight antenna switches or configured to simultaneously select multiple output ports, thereby allowing their use in complex antenna phasing and stacking systems.

DX Engineering RR8B-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. These remote relay boxes are custom-made on a revised stainless steel chassis with integral mounting-bracket flange and include a special RF-shielded high-impact thermoplastic cover. There is also a custom conductive gasket to complete the seal between the cover and stainless steel housing base. A DX Engineering V-Bolt Saddle Clamp is included to mount the RR8B-HP on any tower leg or pipe sized from 1 to 2 in. O.D.

Features of the RR8B-HP Remote Antenna Switches include:

* Fully RF shielded with stainless steel mounting bracket and hardware
* Best port-to-port isolation available: Over 70 dB isolation below 30 MHz, Over 55 dB isolation below 60 MHz
* Loss: Less than 0.1 dB below 60 MHz
* High-RF tolerant, Amphenol UHF female, SO-239 connectors
* Shorted or open selection of unused antenna ports
* Sealed 20 ampere, RF-rated relays
* Safe 12V DC relay operation
* Lightning protection on control lines
* External quick-connect plug for control lines
* Reliable operation in extreme-weather conditions
