[Lowfer] Renamed as Loop Antenna Possibilities

[Stan, W1LE]

  Hello Bill,   Thanks for the details.

One plan is to use 4 each, 50' lengths of #2AWG welding cable in a 200' 
rectangular loop.
Maybe not square, but maybe 70' wide X 30' high, like yours about 10' 
above ground
so I do not hang myself looking for nigh crawlers (fishing bait).
I am thinking more of permanent structural supports like ROHN 25 towers 
to support everything.
The welding cables have  some weight, so I may support them on a 
horizontal non metallic catenary.
Original plan was for 2 each tower, suspending the single loop between 
then at an opportune LOB.
Definite merit to 3 towers and 2 orthogonal loops.

I cut most of the trees down on that side of the yard and they were 
rather short < 50'.
They would really whip around in the wind. Towers would be reasonably rigid.

The ground screen I originally envisioned was 6' wide galvi chain link 
fence material,
either laid on top of or buried under the loop. Maybe on the grass may 
be better
because the acidic soil with acid rain will eat up the galvi/steel in a 
couple of years.
At least on the grass I can easily inspect it.

I inspected the fencing materials I can salvage and they are buried in 
over growth.
Will be quite a job removing them. The dog kennel panels may be easily 
salvaged,
but the dogs will get that material. And should be able to mow over it.

The welding cable insulation is orange in color and probably goodly 
rugged for the intended service.
May have to paint it to tone it down.

Originally was planning to do all RF testing outside at the antenna feed 
but
I am thinking now of just bringing the feeds to the house, any 
combining/switching inside.
The shorter ISO shipping containers 8'W x 20' long x 8' high have merit and
are by far cheaper that any shed for the floor space. And a shielded 
room....
Easy to deliver, but would take some work making pretty for the neighbors.
Larger military shelters are a possibility, then I could argue to the 
taxman they are
not a permanent ground based shelter, but rather a vehicle accessory.
