RE(2): [Lowfer] Loop Ideas ??

[PAUL DAULTON]

Bill
this may be slightly off the subject, but your email reminded me of the
 e/h antenna discussions I have 
had with one of my friends. I went back to the VK5BR site and refreshed my
 memory then checked the 
E/H antenna on google. Made me wonder if this is a practical antenna for
 lowfer work. Lots of  infor out there.
I would need a lot of study to come up to speed on the subject. Has anyone
 tried the E/H antenna on
137 or 185khz?
What do you think?

RX loop enthusiasts:
 
Here's a question for you: With few exceptions every time I run an A/B
 comparison of a loop and a nearby Eprobe at LF I get exactly the same
 weak signal performance - IE the same S/N. This is in a controlled
 environment with no local interference and I always adjust the signals to
 exactly the same level and rotate the loop for maximum signal. The only
 exception in this comparison is when there is a directional noise signal
 and the loop can null this out, making the loop signal have the better
 S/N of the two.
 
I would think that because of the figure '8' reception pattern of the loop
 the sensitivity to typical atmospheric noise would be reduced and the
 loop would always be the winner in these comparisons.  Maybe I'm wrongly
 assuming that the AT noise has equal E field and H field components
 and/or the E field component always the same strength as the H field
 component. Another possibility is that the loop has more noise pick up
 due to its wider azimuth angle pattern. Any thoughts?
