Cable Losses (FCC Regions Only)

The FCC approval for the product is based on tests with a cable loss between the units of not
less than 1.2dB at 5.8GHz. The use of lower cable losses would result in the installation
being outside the FCC rules.
As an indication, 1.2dB of cable loss corresponds to the following cable lengths excluding
connector losses (source: Times Microwave).
Cable
LMR100
LMR200
LMR300
LMR400
LMR600

13.6.2 Antenna Choices

In non-FCC regions, antenna choice is not restricted, but any region specific EIRP limit must
be obeyed by reducing the maximum Transmit power, see Section 5.2 "Licenses and Region
Codes".
In FCC regions, antenna choice is restricted as described in Section 13.6.3 "FCC Antenna
Restrictions on the PTP 58600" and Section 13.6.4 "FCC Antenna Restrictions on the PTP
54600".
The maximum permitted antenna gain depends upon product variant and channel bandwidth
as follows:
x
PTP 49600: 26 dBi
x
PTP 58600: 37.7 dBi
x
PTP 54600 at channel bandwidth 30, 15 or 10 MHz: 34.9 dBi
x
PTP 54600 at channel bandwidth 5 MHz: 33.4dBi
