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.
