Topband: Beverage on Ice

I did this about 10 years ago. I live on the Wisconsin River and it's about
a half-mile wide in front of the house.
I laid out 1000' of #14 stranded, insulated wire. I terminated it with a
200 ohm resistor to a 1/4 wave wire and several short radials running nearly
parallel to the antenna/grounding wires. At the feed end, I used a 4/1
homebrew transformer using one of "Tom's" binocular cores. The transformer
was grounded to a conventional 8' ground rod.
The antenna never worked at all, as far as I could tell. There was no
discernable, certainly not usable, directivity. Why, I don't have a clue.
The techniques chosen were the result of all the best advice I could get at
the time on the topband reflector.
FWIW, the river averages about 10-15 feet deep under the antenna and is
sand/gravel/bedrock. I would love to try this again if someone can help
with an improved design.

I know that Beverages on Ground have been discussed on a number of
occasions, but:
I live on the shores of a reasonably large lake, and at this time of year it
will be frozen to at least 2' and possibly 4' or 5' deep. I believe that ice
is a pretty good insulator, so I wonder about the effectiveness of a wire
just laid on the surface? It would be impossible to retrieve the wire in the
spring so it would have to be fine enameled copper. Even that may not be
very environmentally friendly? If the wire survived the first couple of days
it would be frozen into the ice - it would be at risk from snow machines
until that happened.
This is just speculation from enforced idleness - I cleverly managed to
break my leg during a foolish last check of my receive antennas before
Christmas - so I can't even get into the shack, let alone onto the lake. I
was not very hopeful in any event that EP6T would be workable from here, but
I am determined somehow to get there for K1N...
