If you need the ultimate stealth antenna, why not use a subsurface 40 meter loop suggested by the author of this intriguing article? For a slight sacrifice in receive strength, you can get a reduced noise level plus the added attraction of using an "invisible" antenna. Carl built a 154-foot/46.95 meter loop and placed in beneath his yard. The antenna is quiet, nearly invisible, and fairly cheap. Although you do get a signal that's 2-3 dB below a regular dipole, regular noise is reduced considerably, so the trade-off may be worth pursuing. Underground antennas have been used for years by the world's major military powers, and there is no reason why you can't discover the benefits of this antenna as well. Other ground-mounted antennas can work fairly well on the lower HF and MF broadcast bands. For the latest Amateur Radio news and events, please check ou the blog sidebars.
