Now that radio amateurs have gained limited access to the 630 meter and 2200 meter bands, it may be time to build some simple antennas to make contacts on those frequencies (472 kHz and 137 kHz). Working these bands presents a few challenges, including the lack of ready-made equipment and antennas to make contacts, the relative low efficiency of antennas that are available, and the severe power restrictions imposed by the FCC on those bands (about 1 watt ERP).
Despite these limitations, hams across North America are making some fascinating contacts, often with homebrew equipment and antennas. In this well-made video from Kevin Loughin (KB9RLW), we learn how to make a simple, inexpensive, and fun-to-use magnetic loop antenna for the 630 meter band. Kevin says his design works and is eagerly pursuing more contacts on the low frequencies.
