Scale
1. Selecttherightfrecuency,checkthepositionof
theantennabodyscalewiththegraphicorthe
bandchartFig.1&Fig.2
2. Loosenthesetscrewasahalfturnbyhand.
(Keeptherodelementretracted).
3. Slidetheantennabodytotherequest
frequencyafterstep1andfasten it with the
set screw by hand.Maketherodelement
fulllength.
(Donotuseanytoolssuchasplierswhen
fastensetscrew.Theantennamaybe
damaged).
4. TransmitandmeasuretheSWR.lfthe
tuningfrequencyislowerthantherequest
frequency,maketherodelementshortor
maketheantennabodydown.
TheSWRshouldbelowerthan1.5
dependingontheconditions.Ifnot,please
changetheinstallationconditions.Wealso
recommendusingtheantennatuner.
5. lfthetuningfrequencyishigherthanthe
requestfrequency,movetheantennabody
up.
6. Whenadjusting50MHzband,putthe
antennabodydownandmaketherod
elementfulllength.(Largeradialelement).
7. Whenadjusting144/430MHzbands,putthe
largeradial(Largeradialelement)inthexed
antennaandfastentheradialelement.When
adjust144MHzband,shortentheantenna
body1/4wave,changetheradialelementof
thebodyantennatotheshorterone(Shortradial
element).Whenadjustíng430MHz,makethe
antennabodyretractedwiththelargeradial
element(Largeradialelement).
Adjustment
Atenttion!!!
1. Pleaseinstalltheantennavertically
tohaveabetterperformance.
2. TheSWRshouldbelowerthan1.5
dependingontheconditions.Inthat
case,pleaseusetheantennatuner.
Installation Place (example)
1. Setthebracketwherethe
groundingearthcanbetaken.
(guttermount,trunklidetc)
2. lnstalltheantennaatthecarroof
bythemagnetbase.
3. Setthemagnetbaseonthewood
tableandinstalltheantennawith
approx.10mgroundwireand
connecttothegroundingearth.
4. Installtheantennaatthemetal
