[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.
