500 kHz Projects - Antennas

Click to enlarge472 KHz Antenna by PA3BCA
With a wavelength of 600 Meters most amateur antennas will be 'relatively short'...
I use an end-fed antenna with a total length of about 35 meters.

Click to enlargeActive RX Antenna by PA3BCA
... I therefore decided to build an active antenna that I could place in the backyard on a 12 meter fishing pole, as far away as possible from the house (and the houses from my neighbors, as that is where most of the QRM originates).
I use an end-fed antenna with a total length of about 35 meters.

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.

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.

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.

I needed a simple variometer to be able to vary the inductance in the matching network for my 600 Meter vertical antenna. After considering several options, I decided to build a variometer using some easily obtainable parts. The variometer described here allows a +/- 5.85 uHy swing while inserting a fixed 6.1 uHy inductance in the system.

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.

Magnetic loop receive antenna by PA3BCA
Today I built and placed a magnetic loop receive antenna in the backyard, replacing (for now) the pa0rdt mini-whip I used until July this year. (Between July and today I have not been active on 500 Khz....).

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.
