To determine which antenna or antenna combination is needed for your network:
•
The Yagi antenna is the most powerful and will give the longest range. However, you
can only use it if the data is being received from or transmitted to stations within a
50° angle of the antenna.
•
You should use the omni antenna if receiving or transmitting in multiple directions.
Note:
The best Yagi antenna performance is always achieved by pointing the antenna directly at the
antenna at the other end of the link
Antenna Ranges
Each antenna type in a repeater network varies in the distances it can receive and transmit
data. For instance, the dipole antenna on an integrated sensor suite transmitting to a
dipole antenna on a console is limited to 1000'. A dipole transmitting to an omni antenna
lengthens the distance to 1580' because the omni has a better “microphone.” A Yagi
antenna has an even stronger “microphone” and can “hear” a dipole antenna up to 3,160
feet. The table below shows the total distances of each antennas (receiver and transmitter)
combination. (Examples of dipole antennas are Vantage Pro2 or Vantage Vue integrated
sensor suites and consoles, Envoy, Vantage Connect, standard wireless repeaters, Leaf
Wetness and Soil Moisture stations, Wireless Temperature Stations, etc.).
