[NLRS] Looking for Mounting Help

[Sco oter]

Hi my name is Scott KC0BZG.  I am looking for some help with mounting masts
on my vehicle.  I have a Honda Pilot with no entry other than the doors.
You see, I want to participate as a rover in vhf/uhf contests.
I would like to set up the mast as somewhat permanent but as well as be
able to take down when not in use. I would consider external mounts if push
comes to shove.  I would also need help in installing the mount as I have
no engineering skills at all.
The antennas that I have decided on are a 6 meter loop and a dual band yagi
or quad.  I did it this way because I want to participate in fox hunts as
well.  I know I won't be ready for this month's contests but I will be
ready for contests to come with some help.
Thanks.
