8.5.2 | Cable Requirement
Some remote mount antennas have an antenna cable perma-
nently attached, with an RP-SMA plug, that is simply connected
to the jack on the WMPR. Other remote mount antennas do
not include cable, and require the use of an extension cable.
This extension cable will normally need to have one end with an
RP-SMA plug (inside threads), which will connect to the sensor,
and one end with an RP-SMA jack (outside threads). The jack of
the extension cable will mate with the antenna or the lightning
arrestor. If a lightning arrestor is connected this way, the anten-
na may be directly connected to the arrestor.
Note that at 2.4 GHz., typical antenna cables types have 0.5 dB
of loss per meter (almost 5 dB for a ten meter cable, plus con-
nector losses). Excessively long cable runs should be avoided if
possible.
Refer to Section 7 for approved antenna and cable options.
8.5.3 | Antenna Styles and Mounting Options
Choosing an antenna mounting style depends on application
conditions, antenna benefits and/or features, and user prefer-
ence. The antenna’s gain (discussed further in Section 8.5) to
some extent determines physical size. Another consideration is
the amount of room available in the application.
Straight or Tilt/Swivel:
A benefit of the straight antenna is
rigid design and resistance to being repositioned (shock, vibra-
tion, wind, etc.) when compared to a tilt-and-swivel design. It is
more resistant to weather conditions as there’s no swivel-joint
connection for contaminants to enter. A benefit of the tilt &
swivel design is that it allows easier positioning in relation to
other antenna(s) to obtain a suitable RF signal.

Adhesive mount:
The benefit of a remote adhesive mount
antenna is mounting flexibility to a number of surfaces and
in various orientations. Remember, the surface an antenna is
being mounted to will affect the radiation pattern. Use masking
tape to temporarily attach the antenna. Perform fade-margin
testing, as described in Section 8.7 before permanently mount-
ing.

Permanent mounting:
Pre-clean the antenna’s mounting sur-
face with an alcohol wipe. Peel paper protection from adhesive
strip and mount to the cleaned surface.
