Hi Ian,

Saw you pass through Kempsey yesterday. I'm in town these days and not 
on the property.

I have a bit of a problem with HF antennas on the Hyundai. A bullbar 
mount is not possible due to a ladder style rack mounted on the nudge 
bar to support the kayaks and the body shape doesn't lend itself to body 
mounting. I have to be content with a roofbar mount and that limits the 
30m whip to about 4-5ft stainless steel unit that's bottom loaded. I'm 
working on a 2m 5/8 whip and replacing the coil with whatever is need 
for resonance.
