Medium Wave AM Broadcast Band Resonant Loop Antenna.

There's nothing new about loop antennas, as they dominated receivers for ~50 years until the 1960s transistor radio ferrite rod takeover-itself still a loop ...

The idea with such a loop relates to tuning the simple coil (L) capacitor (C) parallel combo so that the pair "resonate" at a frequency in the band of ...

Clothes pegs fastened to a curtain make for a neat holding system. The loop doesn't need to be perfectly formed either, although it's directional pickup ...

In fact,with the same 60-160pF varicap,6m of 4 wire flat phone cable gave LC resonance in the mid-upper MW band almost as well as 3m of 8 wire cable.

If you'd like to participate in this giveaway, here's how: Simply comment ...

If your soldering is not up to it, then these wire ends can even be joined by cheap screw terminal connectors. Naturally this will also give design ...
