AVW200-series 2-Channel Vibrating Wire Spectrum Analyzer Modules b. Change to a higher gain antenna c. Change polarization (element orientation) of all antennas in your network (yagi or collinear) from vertical to horizontal or vice versa. 9. Interference from 900 MHz transmitter There are some measures you can take to reduce interference from neighboring 900 MHz transmitters: a. Move base station as far as possible from offending transmitter antenna. b. Install 9 dBd yagi and position station so that offending transmitter is located behind or to the side of the yagi to take advantage of yagi's front-to-back or front-to-side ratio (back and side signal rejection). c. Change polarization (element orientation) of all yagi and collinear antennas in your network to see if that reduces effects of offending transmitter. 10. AVW206 or other radio in the network has the wrong Network Address, Radio Address, Hopping Sequence, or Standby Mode It is improbable that an RF401 or AVW206 network that has been working would ever change address, hopping sequence or other settings. However, check the settings for the unlikely event this may have happened. Try "Restore Defaults" and set up RF401 or AVW206 again from that point. 56

Change polarization (element orientation) of all antennas in your
network (yagi or collinear) from vertical to horizontal or vice versa.

Interference from 900 MHz transmitter
There are some measures you can take to reduce interference from
neighboring 900 MHz transmitters:
a.
Move base station as far as possible from offending transmitter
antenna.
b.
Install 9 dBd yagi and position station so that offending transmitter is
located behind or to the side of the yagi to take advantage of yagi’s
front-to-back or front-to-side ratio (back and side signal rejection).
c.
Change polarization (element orientation) of all yagi and collinear
antennas in your network
to see if that reduces effects of offending
transmitter.
10.
AVW206 or other radio in the network has the wrong Network Address,
Radio Address, Hopping Sequence, or Standby Mode
It is improbable that an RF401 or AVW206 network that has been
working would ever change address, hopping sequence or other settings.
However, check the settings for the unlikely event this may have
happened.
Try “Restore Defaults” and set up RF401 or AVW206 again
from that point.
