[Lowfer] rx loop copuling

[Dexter McIntyre W4DEX]

Thanks for all the comments and suggestions.  I presently have a 77 type 
core transformer with 25t to the coax, 75 turns on the antenna.  I put 
this antenna up just to try something different thinking that getting 
400 feet from the house would be quieter.  Also because I have several 
500 foot rolls of high quality 75 ohm coax.  The coax was used for 
restoration of buried transcontinental telcom cables.  It is just 
slightly smaller than RG-11, has double shield of very fine braid wire 
and a slick, tough vinyl jacket.  It was designed to temporarily restore 
service around a cable failure.  The antenna wire may not be WD-1 but it 
does appear to be the same as what I remember stringing while in the 
army.  It is has solid conductors that appear to be steel plated with 
copper.  I did an Ohm meter test just to verify continuity after string 
the antenna but don't recall the resistance.  I'll measure that when I 
make the next change at the feed.  The main frequency range of interest 
is VLF up to 190 kHz.  I suspect I won't be satisfied without tuning the 
antenna to resonance at whatever the current desired frequency may be.  
That's one thing that has impressed my about LF, resonance rules!

More later,
