2.5 Power and Voltage Ratings and Safety Factors
Power and voltage ratings for system components are summarised in the table below. Maximum
ratings are at 40°C. 3 x 1.666 kW DTV transmitter is considered to be applied into the antenna. The
values are for average power, and peak instantaneous in-phase voltages. Main feeder cable losses
have been included in the calculations.
- DRAFT COPY - PENDING TEST RESULTS

Radio Frequency SystemsHandbook No: 49.53678.008
Issue 01 Commercial in Confidence 2-3
Note:
1. Cable power ratings are calculated at the design frequency shown on Drawing 05.70332. Other
ratings are as shown on component drawings in Appendix A.
2. The maximum ratings quoted include an inherent safety factor that can be added to the values in
the table. Ratings are derived from calculated data and in some cases verified by tests on
components. Components may therefore be operated continuously with a safety factor of 1.
Peak Voltage Ratings
The maximum peak voltage rating has an inherent safety factor of 1.4. In deriving peak voltage
ratings of components, the component is tested raising the component to a DC voltage where corona
between outer and inner establishes. The test voltage is then reduced until the corona self
extinguishes. This is said to be the DC test voltage. This DC test voltage is then divided by a safety
factor of 1.4 to provide the maximum component voltage.
Average Power Ratings
The average power rating has an inherent safety factor of more than 1.0.
The component power ratings are average power ratings based upon an ambient temperature of
40°C, unity VSWR termination, and free air circulation. The components are limited by a nominal
inner conductor temperature rise of 62°C and an outer temperature rise of 23°C.
The temperature limitation on power dividers and rigid line is a function of the dielectric material used
in the components and the potential for deformation of components due to differential expansion. As
Teflon is used as the dielectric material in power dividers and rigid line, operating temperatures up to
150°C can be tolerated without long-term harm to the dielectric material. This difference in
temperature provides the inherent safety factor.

4.1 Precautions
Please note the following precautions before commencing installation.
A structural analysis of the tower should normally be completed by a suitably qualified engineer
prior to fitting any new or additional structures to the tower.
RFS has not performed this analysis.
When interfacing EIA and IEC flange connections, inspect the mating surfaces to ensure that
they are not damaged and that they are clean and dry. Flange bolts must be tightened a little at a
time working around alternate bolts.
O-ring seals for all connections must be smeared with silicone grease to provide a good seal.
Vaseline, or other petroleum jellies must not be used on O-rings.
All structural nuts and bolts to be tightened as specified in the appropriate standards.
Note: The customer must ensure that the steelwork on the tower used to mount the array column
will result in the completed column being vertical (within 0.2°).
4.2 Delivery
Check all delivered material against shipping notes and packing slips. Advise the cartage contractor
and RFS immediately if there has been any damage.
Note: Do not attempt any repairs unless advice has been received in writing from RFS.
4.3 Storage
Store materials in a safe location away from vehicular traffic.
Ensure materials are kept dry, and if necessary cover materials with a tarpaulin to prevent water ingress
and damage.

4.4 Unpacking
Unpack all boxes carefully and check the contents against the packing slips.Advise RFS as soon as
possible if there are any discrepancies.
Inspect the unpacked materials. If any damage has occurred the details should be recorded and if
possible the damaged items should be photographed. Where damage to galvanizing is evident, treat
the affected areas with three coats zinc rich paint with a zinc solids content of 85-94% by mass. Each
coat shall have a minimum dry film thickness of 50 microns.
Note: All rigid lines are supplied with protective plastic or metal caps. Do not remove the caps
until the cables or lines are about to be installed.
4.5 Preparation
Suitable lifting equipment is required to raise the assembled antenna into position on the support
structure. Refer to Section 2.1 and Drawing 05.70332 for weight information to determine the lifting
capacity.
4.6 Assembly & Installation
The antenna array is supplied as a pole-mounted assembly ready for installation. Ensure the
antenna is positioned with the TOP label uppermost.
Assemble the antenna to Drawing 05.70332 and parts list in Appendix A, identify the items.
Level 1 is the TOP of the antenna. Ensure the panels assembled to the mounting pole are in a line.
When lifting radiator assembly onto the tower, lifting devices should be attached to/wrapped around the
80NB mounting pole. Do not attach lifting devices to panels or panel attachments. Lift the assembly
with the TOP end up, and fix the mounting pole to the support structure with the front of the radome
facing the direction of maximum desired radiation.
Mount the antenna assembly to the tower on the heading that provides the required coverage (Drawing
05.70332 and Figure B-1 shows the pattern characteristics of the antenna on the nominal heading of
90°T).
4.6.1 Install Power Divider Network
The power divider network is supplied mount to an 80 NB pole. Mounting interface to the tower is not
supplied. Install the power divider network at the height indicated on the drawing and with the input
facing the ground.
Install the power divider network with the input facing the ground (shown on Drawing 05.70332 Sheet 1).
The output ports on the PD31U21E16 power divider have unequal power ratio at the output ports. The
high power ratio output arm is stamped P2 and the low power ratio arm is stamped P1 at the
output arms. Make sure that the distribution cables connect to the correct ports on the power divider
(refer also to the schematic on Drawing 05.70332 Sheet 2). Cable identification numbers are printed
on polyurethane labels attached near connectors.
4.6.2 Install Distribution Cables
This antenna contains the cable set 33.30052 comprising 2 x LCF158-50 cables. Identify the LCF158-50
distribution feeder cables that connect to the radiator inputs by referring to Drawing 05.70332 Sheet 1
and 2. To ensure correct antenna operation, correct cable positioning is imperative. Note: Cable
numbers are printed onto yellow polyurethane labels, attached to both ends near the connectors and
labelled.
Remove the covers from the connectors on the distribution cables, power divider outputs and the slot
cavity inputs. Retain the O-rings, bolts, nuts and washers. Note: Retain cable dome covers for
covering power divider output arm for half antenna operation. See section 4.6.5.

Issue 01 Commercial in Confidence 4-3
At each connection, inspect the mating surfaces for damage and cleanliness. Lubricate the O-ring with a
small amount of silicone grease and position it in the input or output connector.
Form the cable to follow the existing tower structure as much as possible up to the slot cavity module
input connector.
Note: The cables should be pre-formed before connecting to the power divider so that the
connectors mate evenly and no stress is placed on the cable or connector. Bending of the cable
should not exceed the recommended radius. Refer to Section 4.6.3.

4.6.4 Main Feeder Connection
The main input connection is a 1-5/8” EIA flange connector via an AD31-16 adaptor.
Remove the protective cover from antenna input connector and retain the O-rings, bolts, nuts and
washers. Inspect the mating surfaces for damage and cleanliness.
Lubricate the O-ring with a small amount of silicone grease and position it in the feed line connector.
Couple the feed connector to the antenna input. Reasonable force is required which indicates that the
spigot is a tight fit. Ensure that no strain is placed on the antenna input connector by adequately
supporting the feeder cable during connection.
Replace the bolts, washers and nuts and tighten them evenly in an alternating sequence.
4.6.5 Half Antenna Operation
Half antenna operation can be achieved when one of the branch feeder cables is connected directly to
the main feeder cable, bypassing the power divider. Cover the unused power divider output arm with
dome cover cap, check O-ring is in good condition, replace if necessary.
4.7 Pressurisation
This antenna is operated unpressurised, fit the “PD Desiccant Inlet/ Drying Kit” (Item 15) on to the power
divider replacing the brass plug as shown on Drawing 05.70332 and 41.10024.
Desiccant Cartridge
An annual inspection of the desiccant cartridge is required to ensure the indicator in the chamber has
not changed from blue to violet. Should the colour have changed, this indicates the ingress of
moisture into the antenna. The cartridge should be changed using RFS Part Number 158 144 47 and
the antenna reinspected after 2 months.

4.8 Earthing of Main Feeder Cable
Earth connections on the main feeder cable should be made in several places. Recommended feeder
earthing practice is to ground the feeder onto the building or tower at a number of locations. Clamp the
feeder down to the tower at the manufacturers recommended spacing then check that earth connections
have been made at the following locations:
1. At the antenna as close as possible to the antenna input.
2. On the tower at the point before the feeder leaves the tower.
3. At the building entry where the feeder should be grounded to the building earth.
4.9 Assembly Check
Check that the completed installation has been assembled following Drawing 05.70332 and that all
components and cables are adequately secured.
4.10 Tuning
The antenna system components have been optimised in the RFS factory for minimum reflection in a
50-ohm system. A tuning unit has been provided to enable minor on site optimisation to be carried out.
Connect suitable test equipment to the antenna to monitor the return loss.
Loosen the adjustment screw lock nuts. Initially adjust each screw individually noting the number of
turns and the effect it has and then return it to its original position. Repeat this procedure with adjacent
pairs (including the end screws as a pair), adjusting them simultaneously.
Select the optimum result from this, and fine-tune other screws as required. Lock the adjustment screws
by tightening the locknuts.
The adjustment screws have stops, which limit their travel to prevent them from being screwed in so far
that they degrade the power and voltage ratings of the equipment.
4.11 Commissioning
To ensure no damage occurs to the transmitters or antenna system, the antenna's return loss should
be measured prior to applying power to the array. Compare the measured return loss with the
specification in Section 2. Record the results for future reference.
Unsatisfactory performance may result from a damaged antenna, or loose, damaged or incorrectly fitted
connectors.
Commence the power-up by applying low power to the antenna. Monitor the forward and reflected
power at the transmitter.
Progressively increase the power in increments up to the maximum power rating of the antenna,
monitoring forward and reflected power.
Remove transmitter power immediately if any adverse conditions are detected.
Check the antenna feed system for 'hot spots’, which may have been caused by loose connections to
ensure that no heat is being generated at this interface. If 'hot spots' are found, disassemble the
connection and check the fitting of connectors.
Operate the antenna at the specified power for at least three hours. Re-check the antenna
performance.

4.12 Maintenance
The antenna and its components have been designed for high reliability and low maintenance.
A routine mechanical inspection of the antenna every two year, together with a check of the return loss
is all that is required.
Dismantling or repair to the antenna is not recommended. Assembly techniques are employed which
require specialised factory equipment to guarantee the specified performance.
RFS will provide guidance and assistance for corrective maintenance to be carried out.
4.12.1 Working with Teflon™
Many RFS products contain Teflon™. A toxic gas is emitted when Teflon™ reaches temperatures
above 300°C. Extreme care must be taken when working with or repairing product containing
Teflon™ that has been exposed to high temperatures such as during fire or burning from lightning
strike.
Only personnel wearing breathing apparatus should be in the area during maintenance and for one
hour following the venting of the poisonous gases. Before restoring access to the tower or building,
measure the air quality with special equipment used by fire brigade (PPM method or with electrical
equipment). Refer to material safety data sheet.
4.13 Warranty
•Do not exceed the power and voltage levels specified in Section 2.
•Warranty is void when: The antenna is not installed and operated according to the drawings and
instructions contained in this manual; components are damaged by others during installation;
components have been dismantled for inspection before prior approval has been obtained in writing
from Engineering Design Office, RFS Kilsyth, Australia or its designated officer. There shall be no
repair of RFS equipment against the warranty until this authorisation has been received.
