Antenna Feeder System

Table of ContentsMain Antenna Feeder System Composition ............................61GPS Antenna Feeder System Composition.............................71

Main Antenna FeederSystem CompositionAntenna feeder system for the base station includes the O/I portsfrom BTS cabinet to antennas. It mainly transmits and receivessignals to and from BTS. If the system is configured with a tower-top amplifier, install power lines for the tower-top amplifier.

Take one BTS configuration covering three sectors as an exam-ple. When one BTS covers three sectors, each sector can use twounipolar antennas, that is, total six antennas implement spacediversity reception. One unipolar antenna in a sector should beconnected to the combiner and duplexer through the feeder ca-ble to transmit downlink signals and receive uplink signals. Theother unipolar antenna is used only for receiving uplink signalsfrom MS and it should be connected directly to the pre-receivingfilter through the feeder cable.

From antenna to cabinet, the antenna feeder system consistsof BTS antenna, tower-top amplifier (optional), antenna jumper,main feeder cable, grounding clip, lightning arrester, and cabi-net-top jumper, as shown in Figure 32.



Note:

Tower top amplifier is an optional device. Read contract terms forits configurations.

BTS Antenna

The configuration of BTS antenna system is closely related to net-work planning. Antenna feeder system is designed dependingupon on the coverage area and the environment. Before instal-lation, network planning should have the predetermined layout,elevation, tilt, gain, and diversity reception mode for the antenna.

In mobile communication system, BTS antennas are classified intothe following types:


Chapter 6 Antenna Feeder System

Frequency band: GSM900, GSM1800, and GSM900/1800.

Polarity: Unipolar antenna (vertical), bipolar antenna (45)

Directive diagram of antenna radiation: Omni antenna and di-rectional antenna.

Tilt mode: None, mechanical, fixed electrically regulated, ad-justable electrically regulated, and remote controlled.

Figure 33 shows directional antenna and omni antenna.

FIGURE 33 OMNI ANTENNA AND DIRECTIONAL ANTENNA

1. Omni antenna 2. Directional antenna

Tower-Top Amplifier

Electron thermal motion in active parts and RF conductors inBTS receiver can cause thermal noise affecting BTS receiverperformance. Therefore, in order to improve the performance,use tower-top amplifier in antenna feeder system, as shown inFigure 34. Tower top amplifier amplifies the uplink and downlinksignals, hence enhancing BTS coverage area, reducing call dropratio and improving the voice quality.



Note:

Ground the tower top amplifier separately during installation.

FIGURE 34 TOWER-TOP AMPLIFIER

1. Unidirectional tower-top amplifier 2. Bidirectional two-top amplifier

Antenna Jumper

Use antenna jumper when connecting cables in small bending ra-dius. There are helicoid in its surface, making it highly flexible andable to resist the pressure. Use half inch antenna jumpers fromantenna to the main feeder cable and from main feeder cable tothe cabinet, as shown in Figure 35.

FIGURE 35 ANTENNA JUMPER

Main Feeder Cable

Main feeder cable transmits signals between BTS and the antennaunder the environment conditions it can withstand. Feeder cable



can transmit with low attenuation at high frequency, even char-acteristic impedance, and high return loss. As shown in Figure36, common foam insulation feeder cable has internal conductorand external conductor. The internal conductor is wrapped withlow-loss foam insulator, and there are rings on the external con-ductor surface. Feeder cable is covered with a sheath which isfireproof, low smoke, and halogen free. Use 7/8 inch feeder cablebetween antenna jumper and cabinet-top jumper.

FIGURE 36 MAIN FEEDER CABLE

Grounding Kit

Grounding kit can protect antenna feeder cables and the equip-ment against lightning. It is used to ground co-axial cables. Mountit on the tower top, tower bottom, and entrance of the transceiverfor the grounding purpose, as shown in Figure 37.

FIGURE 37 GROUNDING KIT

Lightning Arrester

Lightning causes damage to not only the struck object but also mi-croelectronics equipment in surrounding areas. The strong instantvoltage due to induction in the power cables, data lines, and otherconductors mainly causes damage. Lightning arrester can prevent



cables and the equipment from the lightning current. Generally,lightning arresters are classified into two types: /4 stub and grav-itron.

/4 Stub LightningArrester

As shown in Figure 38, /4 stub lightning arrester is a tri-portpassive coaxial component with external and internal conductorsshort-circuited. Its third end length is one fourth of the centralworking wavelength.

FIGURE 38 /4 STUB LIGHTNING ARRESTER

The working principle is similar to a band-pass filter. At work-ing frequency band, it is equal to connecting together with a maincoaxial cable to infinite impedance. It strongly attenuates the mostdestructive 100 kHz or lower frequency band so that destructiveenergy of lightning is diverted to the ground without causing equip-ment damage.

/4 stub does not get damaged by lightning, since its inner conduc-tor is a 16 mm copper pipe that can withstand 100 KA lightning,which exceeds the current generated by common lightning. /4stub maintenance is free before bandwidth is changed.

GravitronLightning Arrester

Gravitron lighting arrester is a short-circuit protection part encap-sulated in ceramics or glass and filled with low-pressure inert gas.It is divided into two types based on the structure: three elec-trodes and dual electrodes, as shown in Figure 39.

ual pressure

The working principle is gas discharge. When electric field strengthbetween the electrodes exceeds the gas break down strength, itcauses gas discharge, thus limiting the voltage between the elec-trodes and protecting other parts with are in parallel connectionwith the gravitron.

The advantages of the gravitron are high current capacity, highinsulation resistance, and low current leakage. The disadvantagesare high residual pressure, slow response (100 ns), low accuracyof operating voltage, and existence of follow current. Redundantcurrent over two times the value damages the gravitron when itpasses through the gravitron. Therefore, check gravitron interiorwhen lightning exceeds 10 kA for any repair or replacement. Ser-vice life for gravitron is 5 years.

Installation Accessories

Apart from above mentioned main components, some accessoriesare required during BTS antenna feeder system installation. Theseaccessories include:

1. Regulating structure for antenna dip, as show in Figure 40.

FIGURE 40 REGULATING STRUCTURE FOR ANTENNA DIP

2. Feeder window, as shown in Figure 41 and Figure 42.

Feeder window should be prepared and sealed when feeder ca-ble is introduced into the equipment room to ensure equipmentroom environment.

GPS Antenna

GPS is the terminal for locating and navigating through the re-ceived satellite signals. To receive signals, GPS antenna must beinstalled.

Classification Based on the polarization mode, GPS antenna can be classi-fied into two types: vertical polarization and circular polariza-tion. Circular polarization GPS antenna has comparatively bet-ter performance and thus it is commonly used on site unlessin special situations.

Based on the position, GPS antenna can be classified into ex-ternal antenna and internal antenna. BS8800 GU360 uses ex-ternal GPS antenna.

Structure Most GPS antenna uses right-hand polarization ceramic media withthe composition of ceramic antenna, low noise signal module, wire,and connector.Figure 51 shows the GPS antenna appearance.

GPS Feeder

GPS feeder transmits signals between BTS and the antenna un-der the environment conditions it can withstand. Feeder cablecan transmit with low attenuation at high frequency, even char-acteristic impedance, and high return loss. As shown in Figure52, common foam insulation feeder cable has internal conductorand external conductor. The internal conductor is wrapped withlow-loss foam insulator, and there are rings on the external con-ductor surface. Feeder cable is covered with a sheath which isfireproof, low smoke, and halogen free. Generally, 1/2 inch feederis used for GPS feeder.
