To Install antenna options:
1. Physically install the antenna, arrestor or extender as described in the instructions provided
with the option.
2. Launch a browser client to the transmitter.
3. Select the System Settings page. Figure 3.2 on page 21 illustrates the System Settings page.
4. Within the Antenna Type pull-down menu, select the antenna installed on your extender. The
following specialized antennas are available for use with MPX1000 extenders:
a. LGA51G-OMN: A low gain omni-directional antenna tuned for best performance in the
UNI 1 and 2 bands. This is the default antenna.
b. HGA51G-DIR30: A high gain, directional antenna tuned for best performance in the UNII
1 and 2 bands.
c. LGA55G-OMN: A low gain omni-directional antenna tuned for best performance in the
UNI 3 and ETSI bands.
d. HGA55G-OMN: A high gain omni-directional antenna tuned for best performance in the
UNI 3 and ETSI bands.
Use of high gain and directional antennas is suggested when necessary to extend transmission
distance. Use of low gain antennas allow transmitters to be placed in closer proximity. Use of
lower bands antennas are preferable for penetration of walls or other obstructions. In multi-
transmitter environments, use of high band antennas allows for good RF separation from
extenders using low band antennas within the same RF envelope.
5. Within the Lightening Arrestor pull-down menu, indicate if an arrestor is present or not.
6. Within the Antenna Extension pull-down menu, indicate which extension is installed, if any.
Supported antenna extenders include:
a. 1 Meter: Provides a 1 meter antenna extension.
b. 2 Meter: Provides a 2 meter antenna extension.
c. 3 Meter: Provides a 3 meter antenna extension.
7. If you have installed a custom antenna, then you will need to configure the extender for a chan-
nel in the appropriate band. Select Media LAN Settings from the main menu. From Wireless
Channel pull-down menu, select an appropriate channel.
8. Repeat steps 3 through 7 for each active receiver.
These settings allow the extenders to properly configure transmit power to compensate for
extension loss and report true effective radiated power, allowing for high gain antennas.
