GBI Antenna Controller User Manual Ver. 1.00Antenna TuningP/N 1100031 page a3. Antenna Tuning3.1 Factory TuningThe antenna is factory tuned and does not require customer adjustment. If it becomesnecessary to tune the antenna, the following sections describe the process.3.2 Antenna Tuning Equipment!!!! DVM - Digital Voltmeter (mV range).!!!! DVM adapter Cable (see Figure 3-1).! Non-conductive ceramic screwdriver.Figure 3-1: DVM Adapter Cable3.3 Tuning ProcedureAntenna tuning should be performed after the antenna has been installed in its finalposition. This will ensure that the tuning will compensate for the effects of nearbymetallic objects.To tune the selected antenna, follow the procedures below:1) Choose the transmitter of antenna to be tuned by removing it’s SL jumper( for constant RF transmission) and by placing all other SL jumpers inOFF position2) Connect Antenna coax cable or twisted wires to the selected antennaterminal block on the Reader (Figure 0-1)3) Connect the DVM adapter Cable to connector P5 (Figure 0-1).4) Apply power to the Reader.Note: Do not touch the Antenna.

If voltage is highest when the matching capacitor is at theposition of its minimum capacitance, replace the existing Cp capacitorwith one of the next lower value (see Table 4.1).Next, repeat steps 4 & 5.mVCapMax.readinginMax.positionCp Valueto o h ighCp Valueto o lowCp ValueOKVcpmin.pos.Vcpmin.pos.Vcpmin.pos.Vcpmax.pos.Vcpmax.pos.Vcpmax.pos.Cp+VcpCp+Vcp Cp+VcpMax.readinginMin.positionMax.readinginRangeFigure 3-3: Choosing the Antenna Matching Capacitor (Cp)
GBI Antenna Controller User Manual Ver. 1.00Antenna TuningP/N 1100031 page c6) Turn the Antenna matching capacitor clockwise (CW) to reduce thereading by 10mV to 15 mV (i.e. if the maximum reading was 120mV, thefinal reading should be 105mV to 110mV).7) Slowly move a metallic object close to the Antenna assembly (up to 2 cmfrom the Antenna). The reading should rise slightly towards the maximumbefore it drops, when the metallic object is placed very close to the Antennaassembly.Note: If the reading does not rise, but only drops, readjust CCW to reducereading by 10 - 15mV, then re-check with a metallic object.3.4 Antenna Tuning Final Check and AssemblyAt the completion of the procedures in Section 5-3, perform the following procedures:1) Return all SL jumpers to MT position.2) Check Antenna operation with a card.3) Cover and seal Antenna matching capacitor tuning opening with specialnon-corrosive RTV (“Rotacil 1112”, or equivalent).3.5 Procedure for Choosing Coil - Ls- Refer to section 1.1 for connector and jumper positions on card. 1) Connect a 50Ω resistor, to simulate antenna load, by applying a jumper tothe selected transmitter.(J1 - Xmtr. #1, J2 - Xmtr. #2, J16 - Xmtr. #3 or J19 - Xmtr. #4). 2) Remove the SL jumper of the selected transmitter (for constant RFtransmission) and place all other SL jumpers in OFF position 3) Connect DVM to connector P5. 4) Apply power to card and register the DVM reading. 5) Remove 50Ω resistor jumper (see step #1) and connect the selected antennacable to the selected antenna terminal block. 6) Perform antenna-tuning procedure. (Refer to section 1.1). 7) If DVM reading at maximum point is lower by more than 10 mv withantenna than with 50Ω resistor, replace Coil Ls with one of the next lowervalue .(i.e. 3.9µH → 3.3µH ) 8) If DVM reading at maximum point is higher by more than 40 MV withantenna than with 50Ω resistor, replace Coil Ls with one of the next highervalue. (i.e. 3.9µH →4.7µH ) 9) After replacing Coil Ls, repeat procedure from step 6. 10) Return all SL jumpers to MT position.
