SECTION 2.6: INSTALLING THE RF FEED CABLE
Prepare and install an RF feed coaxial cable as follows:
NOTE
: Nautel recommends that you perform the commissioning procedure in Section 2.9,
“Commissioning” , which connects the transmitter to a dummy load, before connecting the transmitter
to its antenna system.
1. Make sure the transmitter is configured for the correct RF output connector. It is factory configured
for the customer’s desired RF output connector [1-5/8 inch EIA (standard), 3-1/8 inch EIA
(optional)or 7/8 inch EIA (optional)].
2. Connect the transmitter's RF output to a dummy load, if available, during the commissioning
procedure's initial turn on.
3. Verify the RF feed cable is in place and is cut to the required length. Do not install the EIA flange
connector at this point.
4. Get two ferrite toroids from the ancillary kit that are sufficient to accommodate the associated
feed cable or hardline. For 1-5/8 inch or 7/8 inch feed cable, use Nautel Part # LP23 (2.187 inch
inner diameter). For 3-1/8 inch feed cable, use Nautel Part # LP32 (4.165 inch inner diameter).
Install two ferrite toroids on the transmitter end of the feed cable or hardline.
5. Install the appropriate size EIA flange connector on the feed cable.
6. If the RF feed cable's EIA flange connector does not have a male connector for the centre
conductor, obtain an EIA bullet for the EIA flange connector. Nautel does not provide an EIA bullet.
WARNING! ENSURE THAT AC POWER IS NOT BEING APPLIED TO THE
TRANSMITTER DURING THIS PROCEDURE.
CAUTION! IT IS EXTREMELY IMPORTANT THAT THE EIA BULLET IS PROPERLY
INSERTED IN THE EIA FLANGE CONNECTOR IN Step 6 AND THEN IN THE CUP
CONNECTOR IN Step 8 . IT IS HIGHLY RECOMMENDED THAT YOU OBTAIN AND
USE A NEW EIA BULLET. USE SUFFICIENT INSERTION FORCE TO ENSURE LOW
CONTACT RESISTANCE. FAILURE TO OBSERVE THESE RECOMMENDATIONS MAY
RESULT IN DAMAGE TO THE TRANSMITTER OR FEEDLINE.
