Shielded loop receiving antenna.
This is a repost of old antenna making video.
Shielded loop receiving antenna. 5 KHz at 400 watts. Belar Shielded Loop Antennas are recommended when excessive electrical interference exists, or in the presence of an interfering station. The main advantage of this antenna is the null provided in direction perpendicular to the plane of the loop. The SLR-40 is a 40-Meter direct-conversion receiver with balanced antenna inputs, and was specifically designed for use with a shielded loop antenna. Which makes it ideal for portable use or you can mount it above a pre-existing vhf antenna, and due to it's small size it is quite rotatable. The stand alone 80m loop is approximately four feet in diameter. Its modular construction facilitates experiments to understand where the Möbius inspired electrical design provides benefit. Folklore claims a small "shielded" loop antenna behaves like an electrical sieve or filter, sorting "good magnetic signals" from "bad electrical noise". In actual operation, it is the shield itself that is the active antenna element.
