Range of Wireless Transmission
The range of your radio transmission depends on many factors. Try to position the
transmitter shelter and your console/receiver as close as possible for best results.
Range is up to 1000' (300 m), line of sight, under optimal conditions. Typical range
under most conditions is 200' to 400' (60 to 120 m), but this may be reduced by walls,
ceilings, trees, or foliage. Radio-frequency interference (RF) can also reduce
transmission distance. Cordless phones (900 MHz) and ham radios are common
examples of RF interference.
A metal roof or other large metal structure can interfere with the signal (aluminum
siding, a furnace with metal ducts, and your refrigerator are examples). Sometimes
transmission between wireless units is obscured by something you cannot identify, or by
some obstacle that you can’t work around. If necessary, consider using
Wireless
Repeater #7626 or #7627
to strengthen the signal or increase the distance between the
anemometer transmitter and the console/receiver.
Testing Transmission from Proposed Location
It is
very important
to test reception from the proposed location
before
permanently
mounting the anemometer transmitter shelter.
Place the transmitter shelter at the intended mounting site, or have someone hold it there,
so you can walk around with the console/receiver for a few minutes. Rotating the
antenna may help to improve reception.
Test wireless reception anywhere you might want to use or mount your console/receiver
now or in the future. Take your time. If you aren’t picking up strong signals where you
intend to place your console, better to move the transmitter shelter now than after it has
been mounted. Experiment.
If you have irregular terrain in the area, it may interfere with the signal. For example, if
the transmitter is mounted downhill from the console/receiver, the ground may block a
wide angle of the transmitted signal.
Mounting the Anemometer Transmitter
The anemometer can be mounted either on a pole or on a vertical surface such as a
fencepost. Remember to mount it so the anemometer arm is extending northward.
(Otherwise, you will need to calibrate the wind direction on your console to display
accurate wind directions. See your Vantage Pro2 or Vantage Vue console manual for
instructions.) The transmitter shelter also can be mounted on a pole or on a vertical
surface.
Mounting Anemometer on a Pole
1. While holding the mounting base against the pole, place a U-bolt around the pole and
through the two holes in the base.
2. Place a flat washer, a split washer and a hex nut on each of the bolt ends.
