      K6STI (author of AO, a very nice MiniNEC engine based modeling tool) had an article in QST or QEX some years back illustrating how even HF Yagis can be tuned for best VSWR near the ground by aiming them straight up. Obviously the reflector needs to be off the ground somewhat. The results appear very much as though the antenna is in "free space". This assumes that the antenna has a good F/B ratio.
      You can model this for yourself. I have used the technique for HF Moxons with perfect results. Tune them aimed into space and put them on the tower and nothing changes.
