Hi Robert,
Most of Esteban's pistol style LRLs have been built with coil transmitters and receivers. From what I understand, at low frequencies (less than 200 khz) these coil antennas are better suited to receiving radio waves than an antenna designed to receive the electric field. because of better electrical noise immunity. After reading many of Esteban's posts about LRL detection from looking at received signals showing a phase shift, I think he believes a coil antenna is much better for locating treasure. I think he is trying to measure changes in the transmitted radio wave in the vicinity of the target without picking up stray man-made electrical static and noise.
I don't believe any electric field or magnetic loop antenna can detect a coin at long distance of more than a few feet. But maybe it is possible a loop antenna can respond to a halo caused by long time buried metal. Little is known about a halo, except it has been proven that there is a column of metal ions that rise through the ground at the location of the long time buried metal. There may also be electrical and chemical properties that allow a VLF radio wave to react to the presence of this halo. Nobody has proven whether a halo exists or whether radio waves can be altered by the presence of a halo. We only have the reports of Esteban and Morgan who say their coil type detectors responded to long-time buried metals.
Now my question to you is this:
1. First, am I correct that a loop antenna will be more immune to electrical noise from buildings and man-made electrical devices, and best for receiving directional VLF signals?
2. If a coil method is better for receiving VLF signals, then what would be a good design to monitor reliably some very small phase shifts in a received signal? Is there a better way than Esteban described using audio demodulation?
I don't claim the halo effect is able to make changes in transmitted or received radio signals, but I am interested to know the best method to construct a portable loop transmitter/receiver to make a real test of Esteban's claims. Are you able to design a TX/RX apparatus that will do this better than Esteban's apparatus?
Best wishes,
