dedicated ground). When using 8-conductor wire the feedline serves as a ground return. Use
of two
DXE-CW9
CAT-5 or standard low voltage control wiring, such as telephone wire, is
acceptable.
General Information
The
DXE-RR2X8B
uses a dual star arrangement of 24 relays to select one or more of eight output
ports when voltage is applied from two 8-wire control lines.
The 24 relays provide greatly improved power handling, port-to-port isolation and SWR over
conventional switches and allow connection between any of the eight antenna output ports from
either the Main or Secondary input ports.
The system offers virtually no loss at HF and excellent low-loss performance (less than 0.16 dB loss
on six meters).
Installation
1. Secure the
RR2X8B
switching unit using the included DXE
-
SSVC-2P
stainless steel V-Saddle Clamp. For outdoor
installations or in moist environments, connectors must face
downward. Use Jet-Lube SS-30, Never-Seez
®
or Anti-Seize on
all stainless steel hardware to prevent galling.
2. Fasten all cables to the mounting mast or tower to relieve strain,
and gently droop the cables to form a drip loop (do not use tight
bends with coaxial cable). Install the
RR2X8B
with the
connectors facing down and use gradual bends or loops in heavy
wires. If the
RR2X8B
is mounted to a wooden pole or building,
a wide copper flashing or heavy wire or strap should be
connected from the mounting bracket to a good ground.
