There are two things you need to do..
First a URL

Check out a few episodes.. Epically those that mention Quartsfest
Second, mid Jan go to Quartsite AZ,, The center of town is the intersection of I-10 and AZ State Route 95
About five or six miles south, on the right, you will find a number of RV's parked for Free on BLM land.
Those folks will show you more RV mounted Antennas than you can imagine.
I have seen portable beam antenns for some of the shorter HF bands.. I use a long wire myself tossed over tree limbs or supported on poles depending on if there are trees to toss over.
The Screwdriver type antennas are popular but I like my long wire, current one is Eighty-something long (About 3 people heights shy of 100')
