[Lowfer] Scrutinize this antenna

[Dexter McIntyre W4DEX]

I've used many different antennas for LF reception over the past 20+ 
years.  A 10 foot diameter tuned loop with a balanced coupled preamp 
most of the time proved to be the best for 1750 and 2200 meter 
reception.  Last summer I ran a 500 foot length of 75 ohm coax down into 
the heavily wooded area to the south east side of the hill where our 
house is located.  Over the 500 foot span the ground drops about 80 feet 
in elevation.  This puts ground level at the house above the tree tops 
at the far end of the coax.  Initially I had the coax connected to a 
single turn loop about 80 feet long by 40 feet high.  That wire didn't 
last very long due to several tree limbs falling and breaking the wire.  
So I just tied the ends of one section of the wire that went over one of 
the trees to the coax.  The wire did receive of course but no better 
than my 2200 meter transmit antenna.  So using some transformers I had 
wound for other projects I came up with what's in the rough diagram at 
the link below.  After multiple comparisons over the past months this 
makeshift antenna has proven to be a good performer from LF up through 
the AM BC band.  So I ask the antenna experts their thoughts and 
suggestions to possibly improve upon this haphazard design.
