4Using the LL-16 Fore- Aft / Left- Right Antenna Setup
5Setting Up Vehicle For Homing Antenna cablesCoupled LEFT RIGHT – FORE AFTAntenna set-upRecommended 20 inches apartPower SupplyUse car battery whenever you canHave extra AA batteries with you
6L-tronics L-per Manual Four Antenna - VehicleAntenna Spacing DesignRecommended for frequency rangeMhz20 inchesRef Pg.16 LA SeriesL-tronics L-per Manual
7Vehicle Coupling Connection Left / Right You will find that the antennas are connected in couples and are identified at the base Left / Right or Fore / Aft.Take one couple, and place one on the Left of the car roof, and one on the right.Vehicle–Coupling Connection3. Take the lead-in cable from these two antennas, and connect it to the“Left / Right”4. Check coax continuity by confirming ant icon in upper right corner of displayLeft / Right
8Vehicle Coupling Connection Fore / Aft Take the second set of antennas, and place one on the front, and the other on the rear of the roof.VehicleCoupling ConnectionConnect the lead - in cable from these two antennas, to the “Fore / Aft” connectorCheck coax continuity by disconnecting the left right coax and then connect the fore / aft coax to confirm ant icon is displayed in upper right corner.Then reconnect left /right coaxForeAftConfirm antenna spacing

10Option Left /Right Antenna Only If the option is to go with one set of antennasSpacing should be 20 inchesAnything beyond this measurement can degrade DF Resolution3. Take the lead-in cable from these two antennas and connect it to the“ Left / Right ”4. Check coax continuity by confirming ant icon in upper right corner of display5. Complete test left / right and centerVehicle–Coupling ConnectionLeft / Right

12Caution If Attaching Transmitting Antenna All transmitting antennas including HF and CBShould be separated from the DF antennas using the minimum safe distancesSwitching diodes can be damaged if transmitting antennas are to close.If damaged meter will deflect to one side only or stay centeredCan confirm watts output of the radio by checking the specs in the radio manual
13Testing HomerOnce antennas is setup and connected to the homer then the reliability check must be completedSet VHF Radio on proper frequency (Training) or on (Distress Freq)Be sure vehicle is away from building and metal fences before checkingWalk around vehicle to different points and key the mike where the LL-16 operator in vehicle will confirm direction on the directional indicator to the radio operator
15LL-16 DF Indicator- 4 Antenna Following illustration will show how the LL-16 DF indicator will be display to different position in relation to the beacon.Note bars will jump in reaction to passing vehicles , power lines , building and fence reflections.Thin vertical center line means ELT signal center left – right.Thin horizontal center line means ELT signal center fore – aft.Low strength number will always be displayed even if there is no signal detected.Strength numbers in this example may not be accurate for this illustration.

34Crewmember Responsibilities Driver - responsible for vehicle and fuel- must drive and park responsibly- will stay with vehicleNavigator sit up front with driver- Operates GPS- Responsible for maps 1:250,000 topo and 1:500,000- Navigation tools- keep record of roads travelFirst aid person recommended to have with crew- responsible for backpack and first aid kit- crew service radio-cell phoneHomer operator - responsible for setup and- testing homer- carry spare batteries- should sit in back seat( Homer may be distraction for driver)
35Vehicle Homing Protocol Travel- All traffic laws must be obeyed including speed limits/seat belts/ operating cell etc- Recommended to have CASARA Logo Displayed on vehicle.- 4 way flashers may be used when traveling below the speed limit or moving on the shoulder of the road.way flashers must be used when parked on the side of a road.- Vehicles are not to travel where they may get stuck.Vehicles are not to drive on private property without owners consent.Airport- Vehicles must NOT travel on airside of an airport unless;they are escorted or have a Flashing orange light,( VISIBLE 360 Degrees)a functioning two way aircraft radio andhave obtained permission from Air Traffic Services prior to entering airside.An unescorted vehicle must have a person onboard with a Airside Vehicle Operators Permit and Restricted Radio Operators License.
36Ground Search Checklist Crew dress for outdoors including proper footwearOrange safety vest for all personnelCommunication-- Hand held VHF air band radio( external antenna preferred)- cell phone , sat phone- 2 radios for crew communication- contact list- communication log and Casara Handbook- clipboard and paperFirst Aid Kit-should be in a backpack- modified with extra latex gloves.- Pocket mask- splinting supplies- copy of first aid manualSurvival Backpack- Blankets , ground sheet, tarp, ties or ties strap- Spare Batteries / Screwdriver- glow sticks- flash light, signal mirror- fire starting aids- water, food- trail markersNavigation gear- GPS ( spare batteries)- Compass- Charts, ruler, protractor (pencils, pen)
37Ready For Search Search briefing completed Casara Handbook in Vehicle? Check list completedSufficient fuel in vehicleBefore leavingCall JRCC and check for updatesLeave a list of crew with contact numbersShould have OPS Norm time establishLL-16 MUST BE ON when enroute to siteHomer on proper frequencyLL- 16 should be set on DF modeL-Per in REC mode doesn’t work as it is directional to the front and left.The needle should be kept at half scale to allow for increases or decreases in signal strengthVolume should be kept constant to allow audible indication of strengthKeep the vehicle moving to allow signal averaging. When moving the signal will be swinging, sometimes wildly, however it will favour one side or the other, that is the side the target is on.Keep switching between fore/aft and right/left, especially if you aren’t on a straight road. This will maintain your picture of the situation.If you have a solid indication to one side of the vehicle and you appear to be getting close, stay with fore/aft more and look for the front to back flip. When this flip happens the target is beside you, mark the map and take the next turn that will take you in the direction of the target (box the target).Always keep sources of error in mind (we’ll deal with these a bit later), buildings, cliffs, power lines, etc..37
38Tracking a Signal If signal is detected stop vehicle where safe. Note location and obtain bearing away from vehicle and be aware of other items that may reflect signals.Mark bearing line on map.Then, select another location to get second bearing.Triangulate the source of the signal.Report to base or JRCC.Watch for centre or change in direction.Always look for sources of error.
39Park vehicle at a safe location Mark LocationHomer operator try to find center(Note things that can interfere with signal)Take bearingNotify operations (Base-JRCC)Plot best route according to bearing
40Park vehicle at a safe location Mark LocationHomer operator try to find center(Note things that can interfere with signal)Take bearingMark on map where second bearing crosses first bearingNotify operations (Base-JRCC)Plot best route to intersectionFor best results try to get a third bearing
41Closing inUse these methods for airports or depots where multiple choices of target exist.When you reach the building circle it about 200 ft away as open space will permit to confirm the right building.Once inside building ask occupants if there is an ELT stored nearby or a radio shop in the building..Select received mode because DF can become unreliable due to reflections in close space.Homer antenna can be folded at this point.Use signal strength meter.Check ELT antenna on each aircraft .Use Handheld Radio.Tune off frequency
44ELT Located Rescue Situation Ground NoteJRCC are unlikely to knowingly send a CASARA ground team to a crash site as first responders.However there may be circumstances where a CASARA ground homing team may, due to lack of valid information, be involved as First on Scene responders to a crash site.Precautions should be followed to protect the victims and those responders approaching the crash site.
46ELT Located Rescue Situation Ground ON SCENE ProtocolCrew prioritizes their initial actions.Confirm roles and responsibilities.Contact JRCC First , then and inform Searchmaster.Report GPS location.Call out and identify yourself as you approach the aircraft advising that you are on your way, to stay calm and do not move.Listen for a response.The objective is to get Emergency Services personal to the scene as soon as possible. Call JRCC First because they would have all the players lined up to contact for the response and you can then contact 911 even just to provide additional information.
