Limitless™ WGLA Series
Magnetic mount: The benefit of the magnetic-mount antenna 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, the user will need to
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. Magnetic-mount antennas are not designed for
mobile applications.

6.2.4 Antenna Adjustment Considerations

The antenna of the WGLA switch and WPMM monitor should be
oriented in parallel. This will, in most cases, allow the longest range
and highest RF signal. The least RF signal is normally in a direction in-
line with the top of the antenna, so avoid having antennas pointed
directly toward or directly away from each other.

Signal Range of an Antenna

The signal range is defined as the physical distance between the WGLA switch and WPMM monitor. It's a function
of the antenna's gain, radio output of the WGLA switch and WPMM monitor (8 dBm or 18 dBm), and cable loss (if
used) in conjunction with the environment (i.e. outdoor urban, indoors, etc.) that the Limitless™ product is operating
in. The Honeywell antenna range calculator can be used to estimate the expected signal range that can be achieved
between the WGLA switch and WPMM monitor with chosen antennas, cable extensions, radio output, etc. The
calculator can be found at www.honeywell.com/limitless.
Signal range specification:
250 m [820 ft] (nominal) – 8 dBm radio output
305 m [1000 ft] (nominal) – 18 dBm radio output
