8. Terminate the transmitter end of the RF feedline with the appropriate mating connector.
Unless otherwise specified in contract documents, the transmitter will accept a 1-5/8 inch
EIA flange connector.
9. If the transmitter will be used to broadcast IBOC, perform a full impedance sweep of the
antenna system. See “Antenna system” on page 8-3 .
10. Arrange manpower or lifting equipment to move and assemble the transmitter. You may
want to use a forklift to move either the transmitter or its power transformer into place for
installation.
11. Implement a safety interlock, if required.
12. If you are going to use an external RF drive, ensure that the drive meets required
specifications.
13. If you are going to use an external frequency reference, ensure that the reference source
meets required specifications.
14. Prepare to integrate the XR6/XR3 transmitter into your station control circuitry, if required.
15. Train your station technicians and operators on the use and maintenance of the XR6/XR3
transmitter.
Selecting a location for the transmitter
To ensure that the desired location for the XR6/XR3 transmitter is suitable, perform the following
tasks:
1. Ensure that the floor area where the transmitter will be located is able to support the weight
of the transmitter system.
The total weight of the assembled transmitter, once installed, is 213 kg (469 lbs).
2. Measure the space to ensure that the transmitter will fit.
See Section 3, “Physical requirements” on page 3-1 for transmitter dimensions.
3. Ensure that transmitter room doors and the pathway of access from the receiving dock or
building exterior to the installation location are large enough to accommodate the
transmitter.
