[Lowfer] Antenna questions

Hi Folks... I have no LF antenna yet, but am thinking about an available
'structure' and some flat multiconductor cable I have.
The 'structure' consists of two 4 x 4s, set in concrete about 8 ft high,
and 8 ft apart. They have an ~ 1.5 ft 'arm' on top. There is also a net
across the beam of the structure-since this was a batting net for my sons.
It is not in use anymore, and I thought it would make a good support
structure for some kind of loop.
Also, I have a roll of flat 48 conductor ribbon cable. Diameter is about 1
ft, so there's a fair amount of wire involved.
The receiver is my Scientific-Atlanta GPD-111
My questions are:
1. In any loop-with-ribbon antenna mentioned, the plan is to use adjacent
wires to make it a series-connected set of wires. Is this a better idea-and
if not, what?
2. Is it worthwhile to use most/all of the ribbon-as opposed to either a
single loop of 'ordinary' (1 conductor I mean) wire; or some construct
using a single loop or two of the ribbon cable.
3. IF I do such a loop, should I make every effort to keep the flat-side
parallel to the plane of the 4X4s, or not worry about that?
4. IF I do such a loop, should I try to imitate some of the old BDCST loops
where a wire starts in the center and is spiraled inwards, keeping the flat
of the ribbon within the plane of the posts? I could use the baseball net
to do this, and it seems like it would be interesting. (???)
5. And, if my GPD-111 has a 10,000 ohm input, what do you think would be
the most efficient way to feed something like this into the 'shack'?
6. Finally, could someone suggest several 'relatively easy' listening
objectives, ranging from ELF to LF?
Thanks for the read.
