I am looking for opinions on whether or not active e-probe vlf/lf antennas
should be grounded at the antenna location. Assume the antenna is located 50
ft or more from the receiver and that the receiver has a good ground.

Hi Doug,
       In my experience I have found getting the active e-probe vlf/lf 
antenna as high above ground level as practical helps more than anything else. I 
have my active antenna hoisted up into a pine tree about 40 ft high and noticed a 
big reduction in noise level AND a big increase in signal levels, compared to 
the same antenna ground-mounted 5ft above ground level. 
       There is no practical way to ground the antenna hoisted up in a tree 
but mine works very well using the station ground back at the receiver end. 
       If the antenna is mounted at ground level best thing to do is 
experiment with a remote ground at the antenna and see if it helps. Everyone's 
situation is different so remote grounding may help sometimes but not always.
