9500 MPR Product Information 371
Disadvantages:
• Interference from other 5725-5850 ISM band transmissions are possible
• Operating restrictions
• 5.725 to 5.850 GHz band
• Performance could deteriorate due to interference as the frequency band becomes
congested.
Antenna Recommendations:
• Frequency – 5.8 GHz
• Size and Type – 2, 4, 6, 8, or 10 foot parabolic; 1 or 2 foot flat panel.
• Parabolic antennas, See Table 8.26.
• Flat antennas, See Table 8.26.
• Gain and 3 dB Beamwidth
This device has been designed to operate with the antennas listed below, and having a
maximum gain of 42.5 dB. Antennas not included in this list or having a gain greater than
42.5 dB are strictly prohibited for use with this device. The required antenna impedance is
50 ohms.
These antennas can only be used in a fixed point-to-point configuration.
To reduce potential radio interference to other users, the antenna type and its gain should
be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that
permitted for successful communication.
The antenna(s) used for this transmitter must be installed to provide a separation distance
of at least 12 meters from all persons and must not be co-located or operating in conjunction
with any other antenna or transmitter.
