      Hello Alan

      I have just started to work with spectrumlab.
      I have this antenna for other HAM purposed and was planning to
      start with this.

      As Final purpose I have planned to monitor Solar SID monitoring VLF stations.

      May for this wire loop antenna is best. (My findings from google) ?
