[TowerTalk] Travel trailers & efficient antennas?

[Mike Smith VE9AA]

I'm in the thinking and research stages of buying a travel trailer (don't
even own a truck yet..I drive a MINI) and was not wondering about the actual
antenna itself (I'll likely use a fantastic Scorpion SA680S---have one on my
MINI and love it), but I am wondering about 2 things.

 

I am primarily a contester and 6m DXer, so my 2 questions:

 

Has anyone operated using a roof mounted antenna on their trailer at the
100w (or 500w) level in a campground and experienced QRM/RFI to or from
others..and

Has anyone added 2 (or 4) raised (or ground) radials extending out some
distance from the trailer to make it more efficient on the low bands?

 

I know my questions are vague to a degree..and I am OK with anecdotal
evidence or comparisons to other antennas in an A/B scenario.

 

Thanks !
