    The best antenna is the one you build yourself.

    MFJ 2990

    I am always asked about my Vertical antenna set up so here it is from bottom up:

    An 8' steel "I" beam sank into the ground with 14" base plate welded for the ALM 31 mast mount.

    Base plate is grounded to two 8' copper ground rods and to the steel frame of my mobile home (72' long) which has two 8' ground rods at each end of the home.

    Twenty foot solid copper wire to an existing radial system for a deceased vertical

    ALM 31' crank up mast to base plate, ground strap from the the top of the 1st section to the metal roof of my home.

    Ten foot mast with 3 Stainless steel guy wires @ 36', 45' to 60' long secured and each attached to 8' ground rods.

    Two 75 meter rotatable dipoles grounded out to mast/antenna base as additional radials, each 14' long.

    Finally the MFJ 2990 43' vertical antenna. I replaced the balun that came with it since it used two hose clamps with a 2kw balun that is bolted not clamped to the mast. It has been up during 50mph winds and is still there.
