3.4.1.2

In-Line Amplifier

 

 

In some cases it may be more cost effective to place an amplifier in the antenna cable
system to make up for the signal attenuation caused by long cable runs. It is
recommended to install the amplifier near the center of the cable run length. Amplifiers
are available from several manufacturers including Odetics Inc. The following table lists
the characteristics of the amplifier available from Odetics Inc.

 

 

Amplifier P/N 0810160 Characteristics

 

Gain

 

33 dB minimum

 

Bandwidth about 1575.42 MHz

 

20 MHz

 

Input Power

 

5 to 25 VDC at 30 mA with voltage pass-through

 

Noise Figure

 

2.5 typical

 

Connector

 

TNC Female In and Out

 

 

 

3.4.1.3

Lightning Protection

 

 

In areas where lightning is present it is recommended to install a lightning protection
device to protect the unit from damage in the event the external antenna is struck by
lightning. A lightning arrester, part number IS-6, is available from
PolyPhaser Corporation, Minden, Nevada, USA. In order to be effective, the arrester
must be connected to earth ground using a very low-inductance conductor. The
arrester should be connected as close as possible to the point where the antenna cable
enters the building. The use of this device requires TNC to N-type connector adapters.

 

 

CAUTION!

 

When installing grounding electrodes, lightening rods, grounding conductors, etc.,
comply to all the rules prescribed by local/state electrical building ordinances and
codes.

 

 

 

3.4.1.4

Weather Proofing

 

 

The antenna enclosure is designed to be exposed to all-weather conditions. However,
care should be taken with the connectors and cable couplers, if used. These
components should be shielded from the elements, or weather protected using butyl
rubber tape. Weather proofing kit P/N 221213 is available from Andrew Corporation,
Orland Park, Illinois, USA. This kit includes butyl rubber and plastic tape. Instructions
are also included with the kit.
