My favorite plan for a portable field antenna is...

        Push up sections of fiberglass mast.   At the top, you
        have a feed point for two opposing dipoles - each
        element of which is set 90 degrees from the next,
        adjacent elements, respectively.  Measure these
        for the two bands you want to work most... and add
        sufficient rope to the end so the construct is both
        antenna and guy line.  Stake the lines with camping
        tent stakes.

        Pound a short piece of water pipe (which is just
        larger in inside diameter than the mast) into the
        ground as a base that keeps the bottom of the
        mast from moving about.  It does not have to be
        deep, just deep enough to keep the mast from
        squiggling about - you can pull it up easily when
        you move on.     Another solution when using
        hollow masts, is to pound a short rod or pipe
        which has an outside diameter less then the
        inside diameter of the mast tubing, and that
        will keep it from sliding about.   A little electrical
        or duct tape will serve to minimize abrasion.

        The four elements of the dipoles serve as radiators
        and guy lines, and if it is not really windy, this
        is sufficient to hold the whole thing together.
        Otherwise a second set of guy lines can be used,
        maybe just 3 more, if you mast is rally tall and
        it gets a bit windy out.

        A telescoping mast with its own quick release
        fasteners often folds down to a single 36-48 inch
        item for traveling.   Roll up the wire elements
        separately, pick up your base rod or pipe, and
        move out when HQ gives the order to bug out.

I have friends using this design for monthly QRP field days during the 
summer months.  This will be a full sized dipole, and way more efficient 
than a BuddyPole, also probably twice as high in the air.
