Antenna Extension Provides Open-Door Policy - 02/16/98 EDN-Design
Ideas Metal garage doors may be solid and secure, but they are not transparent to
radio waves. If your garage has aluminum siding, you may experience frustration with
the operation of your garage-door opener. If you must drive.…File contains many

Antenna Tuning Unit - A simple passive (no power required) circuit to match
an antenna to a radio receiver. This will be a useful addition to the short wave
listener, but in addition a medium wave coil is almost used to tune the medium wave
band…. [Andy Collison] |

ATL3 Loop Antenna (Graham Maynard) - All ATL-3 loop windings are centre
tapped and balanced w.r.t. their amplifier/receiver chassis ground, and therefore
electric field interference pick up tends to self cancel. Magnetic noise fields,e.g.
televisions and the electric meter box, or....(design added 8/03) |
