A Magnetic Loop Antenna for Shortwave Listening (SWL) Now that we’re on the downward slope of sunspot cycle 23 (2004) you may have noticed that some of your favorite broadcast stations don’t come in as strong as they did a few years ago.
The heart of any radio station, be it Amateur Radio, Commercial, Business, CB, Personal Family Radio, or experimenters in extremely low power amateur radio ( QRP as it is called ) transmissions IS the antenna! Without good reception, you won’t hear much. Without good antennas for transmitting, you won’t transmit far, even if you apply high output RF power, or if high output watts are used !

For instance, amateur radio antennas designed as half-wave dipoles at 7 MHz can also be used as 3/2-wave dipoles at 21 MHz; likewise VHF television antennas resonant at the low VHF television band (centered around 65 MHz) are also resonant at the high VHF television band (around 195 MHz).

radio astronomy dish antennas, the huge Mills Cross comprised over 100 dipoles strung between wooden poles planted in a Maryland field. The dipoles were phased to produce a narrow, steerable, pencil-thin beam some 2.5º in width. That is an amaz-ingly narrow beam considering the operat-ing frequency was 22.2 MHz. Ever since this accidental discovery, researchers have aimed shortwave antennas

Connecting two antennas to the radio If you simply connect two antennas in parallel, the math is just like connecting two resistors in parallel: the impedance is halved. This is in principle a problem, because there will be losses due to the mismatch reflecting some received power.

Indoor Stealth Antennas Indoor antennas may work very poorly if your home has aluminum siding, a metal roof, steel construction, or foil-lined insulation.
The great disadvantage of small loops, or any small antenna, is a very small radiation resistance – typically much smaller than the loss resistance, making small loops very inefficient for transmitting; however, small loops are very effective receiving antennas, especially at low frequencies, where all feasible antennas are “small” compared to a wavelength.

With this protection the antenna not only survives a thunderstorm but can also be used in vicinity to transmitting antennas, for example in the garden of a radio amateur or on a sailing yacht. Additionally a VHF broadcast band stop filter can be activated.
A lot of the concerns in transmitting antennas (low SWR, high efficiency, etc) are of diminished importance for receiving antennas, so it’s surprisingly easy to make a perfectly good receive antenna with very little design effort.
