Well, I did it and wow, big difference! I grounded the mast then connected
the coax shield to the mast at the top and my QRM (hash, noise,
what-have-you) went from a steady S9 down to around S4, which is probably
just mid afternoon atmospheric noise. It also seems to have eliminated some
intermodulation problems that I was experiencing around 188 kHz (I was
receiving a very raspy EZT, which is my local airport NDB on 275 kHz). The
entire VLF/LF band seems much "cleaner" now. I am quite happy. Thanks to all
on the good advice.

I'll be the first opinion, ground it at the antenna with a very healthy
RF ground.
