Stealth Attic Antennas - Bill/W6OAV & John/W6NBC

Do you live in a covenant controlled area and wish to put up a stealth compact, but efficient, HF attic antenna? Or, you just don’t have room in your yard for a full sized HF antenna? If so, plan to attend the DRC May 19th Google Meet session. Bill, W6OAV, will discuss his successful experiences with various compact HF attic antennas. Then a video titled “Jumbo Loading Coil for Concealed Attic Dipoles”, produced by John, W6NBC, will follow. John describes a very effective and unique compact HF attic antenna built around a “Super Coil”. His discussion will also include a bit of antenna theory relative to shortened antennas. 0:00 Intro 0:53 About Bill 1:28 HOA Goals 2:19 Agenda 3:27 8JK Antenna 5:58 Compact Dipoles & Beams 7:04 Why bend a dipole? 13:15 Attic Dipole 15:07 Why a bent dipole? 15:51 Modified 8JK Beam 18:16 Commercial Antennas with Bent Elements 21:51 Magnetic Transmitting Loop 25:32 Vertical Loop Radiation Patterns 26:16 Horizontal Loop Radiation Patterns 26:52 Stealth Antenna Farm 30:38 References 33:45 Loading Coil for Concealed Dipoles 35:57 HF Attic Dipoles 36:34 The Solution? 36:51 HF Loading Coils 46:00 Why a large coil? 46:22 Antenna Circuit 54:33 Coil size comparison 56:29 Tune & Match 59:35 Tuning Options 1:01:03 Tuning Principles
