MagneticMountAntenna:RST715

Themagneticmountantennaprovidesaversatilesolutionthat
requiresverylittleinstallation.Thecablesuppliedisthemaximum
specifiedlengthtoavoidanylossofsignalandmaintaincallquality.It
isnotrecommendedtoextendthiscablefurthertoavoidlossofdB
beyondthespecification.

Theantennashouldbeattachedtoametalsurfaceandplacedina
positionthatprovidesthegreatestlineofsitetothesky,freeof
obstructions.


BoltMountAntenna:RST720

Theboltmountantennaisidealforpermanentinstallationsand
enablestheantennasystemtobesecurelyaffixedinlocation.Thecable
suppliedisthemaximumspecifiedlengthtoavoidanylossofsignaland
maintaincallquality.Itisnotrecommendedtoextendthiscablefurther
toavoidlossofdBbeyondthespecification.

Toinstalltheantennayouwillneedto;
1) Useanexistingmountingholeordrillaholethatwillenable
theantennaconnectortopassthrough.
2) Theholesizeshouldnotexceedthesizeof thehexagonal
lockingnut.
3) Removethehexagonlockingnutfromthebaseoftheantenna.
4) Feedthecablefromtheantennathroughtheholeuntiltheantennasitsflush.
5) Feedthehexagonalnutthroughthecableandtightenontheantennatoholditfirmlyinplace.
6) Connectthecabletothecommunicationsdevice.

InstallingGuidelines
Toensuremaximumperformanceoftheantennasystemandtomaximiseavailabilityandreliabilityofservice
theantennamust;
haveaclearlineofsitetothesky
beclearandfreeofobstructions
beclearofmetalobjects
belocatedawayfromothertransmittingdevices
besecurelyaffixedinlocation
notbelocatedindoors
beinstalledinconjunctionwithacertifiedcable

InstallingAntennaCables
Wheninstallingantennacables,followtheseguidelines:
Routeandrestraincablestopreventthemfromvibratingormovingundernormalconditions,whichcould
resultindamagetotheantennaorthecoaxialcableconnections.
Whereverthecablescontactstructures,protectthecablesfromchafingorabrasion.Ifacableneedstobe
bent,avoidkinkingit,andensurethateachbendradiusfollowsthecablesupplierlimits.
Usecoaxialsealant,shrink‐wraptubing,electricaltape,oranothersuitableproducttosealallcable
connectionsappropriatelytopreventmoistureandcorrosiondamagefromweatherexposure.
Mountallantennasverticallyandclearofnearbymetalobstructions
Minimizehorizontalobstructionsasmuchaspossiblebecausetheycancreateareasofpoorsystemcoverage.
Tominimizethelossofradiosignalfromtheantennatotheterminal,thespecificcoaxialcablesystem
betweentheantennaandtheothercomponentshouldbelessthan3dbincludingconnectorloss.

VehicleAntennaInstallation
Theidealpositionforanyvehicle‐
mountedapplicationistocapitalise
onthegreatestgroundplanefrom
thesurfaceofthevehicle.
MarineAntennaInstallation
Theantennamustbeinstalled
withoutobstructionofother
instrumentsorstructures.
Theantennamustnotbepositioned
withinrangeofradarequipmentor
otherRFinterference.
FixedSiteInstallation
Theantennamustbeinstalled
withoutobstructionofother
buildings,chimneysorother
structures.
Considerationshouldalsobegiven
tothesurroundingenvironments
suchaslargetrees,mountainsor
otherbuildings.
