OVERVIEW
TheSWASS-EXT-3-M1AntennaExtensionKitisdesignedforusewithSabineSWM7000
2.4GHzandtheSWASS-EXT-3-M9isforusewiththeSWM6000915MHz.wirelessmi-
crophonereceiversandantennadistributionampliers.BothoftheSWASS-EXT-3units
allowforoptimalplacementofexternalantennasformaximumwirelessperformance.One
SWASS-EXT-3kitcanaccommodateupto70receiverchannels.(Seeblockdiagram
detailonpage10).
An t e n n A Pl A c e m e n t
Extensionantennasshouldbeplacedinanopenareawithinvisualrangeoftheintended
transmitterlocations.NotethattherangeofaTrueMobilitytransmitterisabout100me-
ters,butthatstructuralobjectscanreducethatrange.
cA u t i o n s
• Sincetheinstallationoftheantennasinuencestheoperatingefciencyofthereceiver,
themostimportantruleistominimizethedistancebetweenreceivingantennaand
transmitterforbetterreceptionandperformance.Makesuretheantennascan“see”
thetransmitter.
• Keepthesystemawayfromelectrical-noisesources(electricmotors,refrigerators,arc
welders,etc.).PlacetheSWM7000/SWM6000receiverorSWA6SSAntennaDistri-
butionAmplieratleast1.5metersaboveoorlevel.Keepalltransmittersatleast3
metersawayfromareceiverantenna.
An t e n n A cA b l i n g & cA b l e loss
Whileanextensionantennaaffordstheopportunitytoincreasethedistancefromtransmit-
tertoreceiver,thereisalossofsignalintheinterconnectingcablethatlimitsthatdistance.
Themaximumconnectionlengthisdeterminedbythetypeofcableused,andthedegree
ofsignalattenuationacceptable.
Let’spresumethatanacceptabledegreeoflossoverthetotalcablerunis6dB.Without
externalsignalboosts,thedifferentcablesshowninthetablewouldthenallowmaximum
lengthsrangingfromlessthan4M(RG-58)to24M(RG8/U).Thus,forapassiveexten-
sionantenna,yourchoicesaretolimitthecablerun,orincreaseyourbudgetandbuythe
moreexpensive,thickercable.

Fortunately,Sabine’sSWASS-EXT-3ActiveExtensionAntennaoffersafarbetter,more
cost-effectivesolution,duetoitsbuilt-inactive18dBsignalboost.Inthecaseoflow-cost
RG-58cable,addinganSWASS-EXT-3toyoursetupincreasestheacceptablemaximum
cablerunbymorethan4times,to14meters.WithRG-8cable,themaximumlengthis
extendedto88meters!
Power for the ExtensionAntenna is delivered from any Sabine SWM7000/SWM6000
seriesreceiverorSWA6SSAntennaDistributionAmplier.
AnadditionaladvantageofusingSabine’sSWASS-EXT-3ExtensionAntennastemsfrom
itsmorefocused,directionalnature.Sabinereceiver’scoaxialdipoleantennas(standard
equipmentthatmountdirectlyonthefrontorrearpanelsofthereceiverorSWA6SS)are
moreomnidirectionalinnature.Incontrast,theSabine’sExtensionAntennaissensitive
toRFreceptionina180-degreearcinfrontofitsmountedposition.Itextendssensitivity
tothefrontandoff-axissidelocationsasitincreasesrearRFrejection.
Themultiplefunctions(relocationofantenna,boostofsignal,directionalsensitivity)of
Sabine’sExtensionAntennameantherearemanyapplicationsinwhichitsadditiontoyour
systemcangreatlyenhanceperformance.Here’sapartiallistofsuchapplications:
1. Antenna repositioning.  Provides solutions when receiver placement options are
limitedorchallenging.Sabine’sExtensionAntenna’smultiplemountingoptionsallow
higherplacement(wallmountormicrophonestandmount).
2. Barriers interrupting transmission.Anytimeabarrierinterfereswithtransmission
andreception,Sabine’sSWASS-EXT-3canbemountedonthetransmittersideofthe
barrierwithcableconnectionsmadeonthereceiverside.Themostcommonsitua-
tionofthisnaturewouldarisewhenreceiverandtransmitterarelocatedinseparate
rooms.
3. Expanded or directional sensitivity required. Sabine’sExtensionAntennapicksup
ina180-degreearc,focusedtowardsthefront.Receptioninthisarcisenhanced.
4. Rear RF rejection required. BecauseSabine’sExtensionAntennaislesssensitive
tosignalsreceivedfromtherear,itcanbepositionedtorejectanysuchdirectionalRF
interference.
5. Extended operational range. Givenapotentialmaximumcablelengthofalmost90
metersfromExtensionAntennatoreceiver,Sabine’sSWASS-EXT-3allowsmoreop-
tionsforextendingthedistancebetweentransmitterandreceiver.ConsiderthatRF
signalstrengththroughairisdiminishedbythesquareofthedistance(twiceasfar
away=¼thesignalstrength),whilesignallossthroughcableis(roughly)inversely
proportional(twiceasfaraway=½thesignal).Thatmeansyoucanuseanextension
antennatoreplacetransmission-through-airwithtransmission-through-cable,tohelp
minimizesignalloss.
6. Variable Gain. Thismodelallowsforcontinuouslyvariablegainsettingsfrom0to+44
dB.Thereshouldbeaminimumof12dBofcablelossbeforetheantennagainisset
tothemaximumgainsettingof+44dB.Ifmaximumgainissetwithlessthan12dB
ofcablelossthereceiverfrontendmaygetoverloaded.Refertothechartatleftand
usemaximumgainonlyforextendingthemaximumpracticaldistanceofthecableyou
areusing.Seepage7forinstructionsonsettingtheantennagain.

InstructionsforadjustingthegainonSabineSWASSextensionantennas.
Introduction
TheSabineSWASSextensionantennaisanactiveantenna.Thismeansitcanamplifythe
RFsignalitreceivesbeforetransmittingittothecableitisattachedto.Thereasonithasthis
abilityistomakeupforthelossinthecableconnectingittotheAntennaDistributionAmplier
(ADA)orSWMreceiver.Forexample,RG8cablehasalossat2.4GHzofapproximately
7.4dBper100feet.Therefore,thecorrectgainfortheSWASSwouldbe7.4dBfor100feetof
RG8.Althoughitmightseemlikeagoodideatoaddevenmoregaininanattempttoextend
therangeofthetransmitters,don’tdoit.Itwillcausesignalclippinginthereceiverwhichwill
leadtoaudibleartifactsandreduced,notincreasedrange.Thisdocumentexplainshowto
correctlysetthegainpotontheSWASSforoptimumrangeandsystemperformance.
SettingtheGain
NOTE:YouwillneedtohaveoneofyourreceiversconnectedtoaPCrunningtheSabine
SWMremotesoftwaretoperformthisprocedure.Onceyouhaveyourantennasinstalledin
theircorrectpositions,followtheprocedurebelow.
1. Turnonallofthetransmittersthatyouwillbeusingwithyoursystem.Makesurethey
areallondifferentchannels.Leaveonechannelopeninthemiddleofthechannellineup
foruseinthecalibrationprocedurethatfollows.Forexample,ifyouareusingchannels1–

common so u r c e s o f rf in t e r f e r e n c e
Thetypical sources of interference forconventional wireless mics can behigh-powered
broadcasters such as radio stations and TV transmitters, or other short-range wireless
devices, including multiple radio microphones operating at the same location (either by
design,orbycoincidence),thatoperateinproximate(orharmonicallyrelated)bands.Less
commonly,interferencemayarisefromspuriousoutputsemittedbyelectronicequipment
(notablycomputers,printers,orsimilardeviceswithdigitalclocks),faultyelectricalequip-
ment,neonsigns,dimmersandlightingcontrollers,andsoforth.
ManyUHFandVHFmicsareespeciallyvulnerablebecausetheysharetheRFspectrum
withtheveryhigh-poweredtransmittersfortelevision.Thecomingconversiontodigitaland
high-denitionbroadcastwillincreasetheproblemsforUHFandVHF.
The2.4to2.4835GHzfrequencybandisnotonlywellabovethefundamental(nominal)
transmissionfrequenciesofsuchstronganaloganddigitalbroadcasts,butalsohighenough
toescapeinterferenceproblemsoccurringatthestrongrstharmonicofeventhehighest
digitaltelevisionbroadcast.Thebandisapprovedworldwideforavarietyofuses,including
suchdiversetransmittersasbabymonitors,garagedooropeners,wirelessLANs,amateur

1. Microwave ovens
Inthevastmajorityofsituations,interferencefrommicrowaveovenswillnotaffectperfor-
manceofyourSWM7000/SWM6000seriesmicrophonesystems.Sincebarrierssuchas
wallsworktoblockinterference,amicrowaveovenwilllikelypresentaproblemonlywhen
locatedinfairlycloseproximitywithinthesameroomasthewirelessreceiver(orreception
antenna).Seecautionbelow.
Commercialqualitymicrowaveovenspresentabiggerpotentialproblem.Theysweepover
awiderbandoffrequenciesthanthelimitedbandaffectedbyconsumerunits,anduse
twomagnetrontubeswhichalternatetoavoidinactivityduringapowercycle.Fortunately,
Sabinesystemsareonlyaffectedbysuchovensincloseproximitytoreceiverantennas.
Thatprotection,plustheavailabilityofmultipleRFchannelstochoosefrom,makesserious
interferenceproblemsarisingfrommicrowaveovensavoidableandunlikely.Seecaution
below.
2. Wireless Local Area Networks (WLANS)
Thesecomputernetworkdevicesallowcomputerstoconnectviawirelessdevicesthatact
asbothreceiversandtransmitters.Theselow-poweredtransceiversoftenhaveselectable
channelsandcanutilizetheentire2.4GHzband.Ingeneral,Sabinemicrophonesshould
notbeaffectedbytheseWLANSbecausetheirspreadspectrumtechnologydoesnotpres-
entaproblemfortheSabineSmartSpectrumTMsystem.Seecautionbelow.
3. Cordless phones
Thesehometelephonesbroadcastatverylowpowerandshouldnotpresentinterference
problemsforyourSabinewireless.Thisisespeciallytrueifthetelephoneusesspread
spectrumtechnology.Seecautionbelow.
4. Wireless Video Cameras
Certainwirelessvideocameras(X10,forexample)usethe2.4GHzband.Thesedevices
arealsoverylowpowerand,ingeneral,shouldnotpresentaproblemwhenusingthe
SWM7000/SWM6000system.SeeSection5ReceiverOperationformethodsofoptimiz-
ingclearreceptionandminimizinginterference.Seecautionbelow.
Asageneralprecaution,keep2.4GHzcordlesstelephones,microwaveovens,
WLANantennasand2.4GHzwirelessvideocameratransmitterstwicethedistance
fromyourSabinewirelessmicrophonesystemantennasasthatofyourSabine2.4
GHztransmitters.

tocauseinterferencewith,orsufferfrominterferencefromtheuseof,Sabine’ssystems.
Your rst step in checking for interference should be utilizing the Scan function in the
