Cisco Vandal Resistant Omni-directional Dome Antenna for 860-928 MHz ISM, WPAN and LoRaWAN (ANT-UN-MP-OUT-QMA)
Table 1 RF Specifications
Note 1: Antenna has been designed and tested to have excellent performance with and without a ground plane over the full
860-928 MHz frequency range. It can be installed on a metallic or non-metallic surface. RF parameters in the table are provided
for both cases of ground plane vs no ground plane.
Note 2: Peak gain of monopole antennas installed on a finite size ground plane will not be at horizon, and will be elevated above
the horizon. In contrast, typical terrestrial radio deployments with omni-directional antennas involve communications near the
horizon. Therefore, in the most common deployment scenarios the gain at horizon is a more useful parameter than peak gain.
Note 3: The minimum horizon gain specification shows whether an antenna has radiation nulls in azimuth. Nulls are directions
in which the antenna has poor gain (e.g. -6 dBI, -10 dBI, -20 dBI or worse), and nulls often result in severe transmit and receive
signal loss in the direction of the null. The ANT-UN-MP-OUT-QMA antenna has a smooth horizon or azimuth radiation pattern,
and does not have azimuth pattern nulls. When evaluating omni-directional antennas, it is important to ensure that the antenna
pattern does not have nulls in azimuth, to ensure good transmission and reception signal quality in all directions at horizon.
Note 4: All provided RF specifications include the RF loss of the integrated 5 foot cable.
