NX5 PRE-INSTALLATION MANUAL

RF OUTPUT REQUIREMENTS

VERSION 0.1  2015-08-01

PAGE 1.6.1

SECTION 1.6: RF OUTPUT REQUIREMENTS

This section describes requirements associated with the antenna and RF cabling to be used with the 
NX5 transmitter. 

Antenna considerations include the following: 

Installing an Antenna Feedline

Antenna Feed Cable - see page 1.6.2

Antenna System - see page 1.6.4

For detailed information about protecting the antenna system from lightning strikes, see Nautel’s

 

Recommendations for Transmitter Site Preparation Manual

. 

Installing an Antenna Feedline

When installing an antenna feedline for the NX5 transmitter, perform the following tasks: 

1.

Ensure that the RF feedline that will connect the transmitter and the antenna system has a suitably 
rated coaxial cable (see 

“Antenna Feed Cable” on page 1.6.2

). 

2.

Connect the shield of the antenna feedline coaxial cable directly to the station reference ground 
where it enters the building. For more information about the station reference ground, see 

“Station 

Reference Ground” on page 1.5.10

. 

3.

Install lightning protection devices. For more information about lightning protection, refer to 
Nautel’s 

Recommendations for Transmitter Site Preparation Manual. 

4.

Pass the center conductor and the shield of the feedline cable through a ferrite toroid that is 
positioned between the shield ground at the building entrance and the shield termination at the 
transmitter. Install the ferrite toroid prior to installing flanges on the feedline cable. Nautel 
provides suitable ferrite toroids [Nautel Part # LP23 (2.187 inch inner diameter)] in the ancillary kit 
with transmitter delivery.
