RDL-3000
5.3

RF Ports

The two RF ports (N-type / F connectors) conduct RF signals between the RDL-3000
and the antenna system (ordered separately). The RDL-3000 can be operated using a
SISO (single antenna) or MIMO (multiple antenna) system.
Failure to follow the following requirements may result in damage to the RDL-3000 unit,
requiring that the unit to be returned for factory repair.
4. Both RF ports must always be electrically terminated to an antenna or other RF terminator
device when the RDL-3000 is powered-on.
5. When operating in SISO mode, the unused RF port must be electrically terminated.
6. Do not disconnect any RF cable while the RDL-3000 is powered-on.
A factory-installed protective weatherproof plastic cap is installed on the RF ports. When
a cap is removed to install an antenna cable, the port must be adequately
weatherproofed.
5.3.1

RF Cable Connections

RF jumper cables with type-N/M connectors are provided to connect the RDL-3000 unit
to the antenna system. The cable length supplied is based on the mounting kit. Apply a
small amount of weatherproofing grease to the nut threads at both ends of the RF cable
Connect the RF cable between the RDL-3000 RF port and the antenna RF port.
The connectors must be tightened to the required specifications. RF connectors must be
finger-tight plus 1/8th turn only. Use the proper tool for final tightening. Using excessive
force (over-torque) or the incorrect tools will damage the connectors on the antenna and
RDL-3000 and may defeat the connector weatherproofing features.

Important: The N-type connectors on the RDL-3000 must be weatherproofed. The
following section provides a pictorial primer on correct weatherproofing procedures.
5.3.2

Weatherproofing RF Ports

The importance of proper weatherproofing can not be overstressed. Both ends of
the RF cable must be weatherproofed.
Redline recommends sealing tapes designed for outdoor use:
- Scotch 2200 series of Vinyl Mastic rolls
- Scotch 130C Linerless Rubber Splicing Tape
- 3M Scotch Super 88 Electrical Tape
These heavy-duty tapes, which are weather, abrasion, and UV resistant, can be
purchased at most hardware stores. Rubber mastic putty or duct sealing putty must also
be used to complete the weatherproofing. The professional installer may use his own
weatherproofing materials provided they are not silicon-based Redline does not
