SWR off the chart

[somis81]

JJ, Buckeye, thanks for the help, the REF is reading 7%. I have the handheld on 4 watt hi power. The president randy has great reviews with no complaints about power.
I grounded the antenna base to the engine compartment battery grounding bolt with a spare battery cable, still no luck, still way over 3 SWR. My motorhome is aluminum and the antenna may be too close to the body and mirror or maybe it's the wrong kind of antenna.
I can hear truckers talking on channel 19 with the Firestick, but the rubber ducky doesn't pick up anything.
Not sure what to try next.
