500 kHz Projects - Antennas

Click to enlarge" ADA" : An Active Differential Antenne For 5Hz – 500 KHz by I1RFQ
This article describe the design, construction, measurements and receiving experiences made with such “exotic”antenna that fully covers ELF – SLF – ULF – VLF - LF and part of the MF.

Click to enlarge10' x 20' Active Loop by VE7SL
The new 'loop' is not really loop-shaped but is rectangular (10' x 20') and more like a Flag antenna shape. I considered a Flag but really don't need any back-end nulling capability since I'm mainly interested in listening to the east and to the north.

Click to enlargeA Broadband Shielded Receiving Loop for LF DX Work by VE7SL
This is a description of a broadband ( ~40kHz - 500kHz) shielded receiving loop and preamplifier suitable for low-noise LF reception. The preamplifier was originally developed by the late Ralph Burhans, a dedicated engineer and LF experimenter.

Click to enlargeA Simple Loop Antenna for 500 KHz by WA1ZMS/4
The loop frame is made from 1/2" square hardwood strips that are 24" long. They are nailed together like a plus sign. Holes are drilled in each end of the arms to string the wire. In the antenna shown here, the wire is 11/36 Litz wire.

Click to enlargeA Tree Antenna for the 600 Meter Band by W5JGV
My interest in tree antennas goes back many years, when I first read about some experiments using coils to couple RF energy to trees. Unfortunately, I neglected to save the article, and it was only much later that I was able to locate the source for the article.

E-field Probe Antenna by G3XBM
Recently I have been trying out a small active voltage probe antenna to aid reception on the LF bands. I used a PA0RDT designed active antenna to listen successfully to amateur signals on both 500kHz and 136kHz.

New LF / MF Loop by VE7SL
The new 'loop' is not really loop-shaped but is rectangular (10' x 20') and more like a Flag antenna shape. I considered a Flag but really don't need any back-end nulling capability since I'm mainly interested in listening to the east and to the north.
