WebApr 19, 2024 · Keep the base small, as the antenna will likely be operated on a desk or table. Operation. The antenna is intended to operate in close proximity to the radio, such as on a desk or table. There must be sufficient space to rotate the loop laterally. As described, this antenna has a range of 2.6 MHz through 12.3 MHz with a band overlap around 8 MHz. WebAloop antenna is a closed-circuit antenna—that is, one in which a conductor is formed into one or more turns so its two ends are close together.

WebThe MFJ-1886 Receive Loop gives you tremendous power to copy weak stations through impossibly strong levels of QRN or QRM. Covering AM broadcast through 30 MHz and beyond, its superbly directive element and bullet-proof low-noise preamplifier dig out buried signals normally lost when using wire antennas. With the MFJ-1886 you get:
