Section 4: Installing the RF feed line
Prepare and install an RF feed coaxial line as follows:
1. Connect the VS1’s RF output to a dummy load, if available, during the commissioning
procedure's initial turn on. If the RF feed line is not connected to a switching circuit that
permits antenna/dummy load selection, connect the RF feed line for the dummy load to the
transmitter's RF output until transmitter commissioning is complete.
2. Verify the RF feed line to the antenna system is in place and is cut to the required length. Do
not install the feed line’s mating connector (7/8-inch EIA or 7/16 DIN) at this point.
3. Obtain one or two ferrite toroids (Nautel Part # LP23, 85.7 mm) from the ancillary kit.
Install the ferrite toroid(s) on the VS1 end of the RF feed line. If practical, the RF feed line
should pass through a minimum of two times (one turn) (see
Figure 4.1 ).
Note:
Nautel recommends that you perform the commissioning procedure in Section 8,
“Commissioning tasks” before connecting the transmitter to its antenna system.
Note:
The VS1’s RF output connector is a 7/8-inch EIA connector or 7/16 DIN
connector, which is user-specified.
