For Cellular Communication Antennas

For Directions on installing the Omni Outdoor Cylinder Antenna go Omni Directional Antenna_Installation Guide

When using an external antenna, placement of that antenna is critical to a solid data link. The key to the overall robustness of the communication link is the height and placement of the antenna. In general, communication modules with a higher antenna placement (roofline height) will have a better communication link. An adjustment of as little as 2 feet in antenna placement can resolve some noise problems.

1. In order to get the best signal, HydroPoint recommends: 
   1. placing the antenna 10-25 feet away from tree canopies and on top of a roofline if close to a building
   2. mounting the antenna to a metal pipe that is driven into the earth, which creates a good earth ground for the antenna.
   3. Ensure as much vertical separation as possible between all antennas. Other antennas in close proximity are a potential source of interference. HydroPoint recommends 10’ of vertical separation from other high power.
   4. Cellular signals can penetrate plastic but not metal. If placing a controller inside a large metal enclosure be sure to install an external antenna. 
2. To view signal strength, press the COMM button. If the signal strength is acceptable, the word “OK” will display in the VIEW PHASE INTEGRITY screen. 
   1. A signal level above 10 is strongly preferred. If the signal level is low (below 5) there may be a line-of-site issue with the antenna.  The antenna may need to be redirected or increased in height.

A Central Yagi antenna is also available, however we do not prefer this accessory as there as there have been directional problems reported.
