Mast mount:
The benefit of the mast-mount antenna is its
rigid design and resistance to displacement when subjected to
shock, vibration, wind, etc. It can be easily mounted high above
the ground to obtain greater RF signal performance and it with-
stands winds up to 100 mph.
Catalog listing: WAN06RNJ
Mast-mount bracket
(Included with the 8 dBi antenna):
Attach antenna to its mounting bracket. Tighten nut. Assemble
two U-clamps around mast and tighten nuts. Ensure provided
lock washers are compressed to a flat condition.

Magnetic mount:
The benefit of the magnetic-mount anten-
na is its ability to mount on any ferrous-metal surface and in
various orientations. A smooth metal surface is preferred to
allow the best attraction of the magnet to the surface. First,
determine if the magnetic attraction is sufficient to hold the
antenna in the desired position (i.e., shock, vibration, etc. in the
application). Placing the antenna in a location where it cannot
be inadvertently displaced may help.

SP-010:
These magnetic-mount bases are not designed for
mobile applications.
Catalog listings: WAN09RSP & WAN10RSP:
These magnet-
ic-mount antennas are designed for mobile applications and
can withstand winds at >150 mph.

Thru-hole mount:
The benefit of the thru-hole mount antenna
is it allows the cable to run “thru” the mounting surface. There
is also an adhesive material between the antenna housing
and the mounting surface for seal protection. This is a very low
profile, rugged design [approximately 30 mm (1.18 in) height]
when mounted and can also can be used in mobile applica-
tions.

8.5.4 | Antenna Adjustment Considerations
The antennas of the Limitless™ input and WMPR receiver
should be oriented in parallel as best as possible. This will, in
most cases, allow the longest range and highest RF signal. The
least RF signal is normally in-line with the top of the antenna,
so avoid having the antennas pointed directly toward or directly
away from each other.
