Note:Useofanantennatunertoextendoperatingfrequencyoftheantenna
beyonditsnative2:1SWRrange,whilerunningfullratedpowerwillvoid
thewarranty. Suchoperationshouldthereforebedonewithextremecaution
andatgreatlyreducedpower. Alltuningadjustmentsshouldbedoneatlow
power,lessthan100W.

TheR9hasahighwindloadatthetopoftheantenna.
Guyingishighlyrecommended. A guykitwillstabilize
theantennainseverewindconditions.Optionalguying
kitmodelnumberR8-GKisavailable.Flexingofthe
antennainstrongwindscanstresstheelementsand
causethemtobecomeloose.
