1.5 Antenna Orientation
The radios come with high quality dipole antennas. Dipole antennas perform the best when
information is being received on the broadside of the antenna. To maximize the performance,
mount the radios so that their antennas are in an upright position and are on equal
elevations.
Figure 6: Correct/Incorrect Antenna Orientation
An inclination of more than 45 degrees from a perfect parallel position may reduce the
performance of the radios by more than half. However, dipole antennas are not directional
and will transmit signal equally for 360 degrees around the antenna.
A difference in elevation may be allowed depending on the distance and orientation of the
antennas. If both antennas are angled at 45 degrees, performance can again be maximized.
Refer to
Figure 7 for details.

1.6 Channel Number
The channel number is a parameter that must be the same for all server and client radios in
the same network. Each product line will have a set of channels on which the radios may
operate. The Venus 1500 radio can operate on channels 67-74. The default channel is 67,
which corresponds to address 0 on the radio’s hex dial. To change the radio address, refer to
Section 3.1 .
