[Antennas] help with temporary mobile hf installation

[Gary Lee]

I am taking a trip up to northern wisconsin in two weeks.  I will be riding
in a 1995 dodge ram half ton pickup.  
I would like to do some operating during the trip.  I am totally blind so
won't be driving at all.

The truck sits very high off the ground (cab top almost 6 feet).  Need
recommendations for an antenna under the normal 8 foot length for use in a
mag mount.

Also, how big and what type mount should I use?

I plan to operate 20 and 15 meters, maybe 40 if I can make it work.

Rig will either be an argonaut 509, hw-8, or norcal 20.  All depends on
whether I can get dials brailled and such.
I will be taking my mfj 971 tuner allong.

Thanks for any help.
