For One and All,
THE PROFESSIONAL {AMATEUR} VIEW POINT
- - - HAMMING IT UP ! - - -
The 1/2 Wave Length Dipole and the 1/4 Wave Length Vertical are both
good Technical {Reference} Antennas for the "Specific Frequency"
related to their Measured Wave Lengths. For Amateur {Ham} Radio use
where you are Operating in a Certain Amateur Band and on a Single
Selected Frequency; they are excellent Receive and Transmit Antennas.
SHORWAVE LISTENING (SWL) - HEY IT'S JUST A HOBBY
[ KEEPING IT SIMPLE AND PRACTICAL ] {KISAP}
The Random Wire Antenna that is generally good on All Frequencies
across the Shortwave Bands from 1.8 MHz to 30 MHz is the most commonly
used Antenna for Shortwave Listening (SWL) and thus is the Practical
{Reference} Antenna for the Shortwave Listener (SWL). It is simply
A-Common-Point-of-Reference for All Shortwave Listeners (SWLs) to
'compare' the relative perfromance of their respective Shortwave
Listening (SWL) Antennas. The Random Wire Antenna, while not very
good on any Specific Frequency is simply so-so-good across All
Shortwave Frequencies. To some extent the qualities that make an
'un-tuned' Random Wire a poor Amateur Antenna; are the same qualities
that make it a very good Shortwave Listening (SWL) Antenna. The
modern solid-state General Coverage 1.8 MHz to 30 MHz Shortwave
Receiver has enough Gain and sufficient Dynamic Range to make full use
of the Signal Levels that can be producted by a Random Wire Antenna
that is 35 Feet to 105 Feet long. For most Shortwave Listeners (SWLs)
what more do they need other than Lower Noise and Better Signal Quality
relative to Noise. {Improved Signal-to-Noise S/N Ratio}.
The-Bottom-Line : The Random Wire Antenna is :
+ Simple
+ Practical
+ More Than "Good Enough"
For the vast majority of the Shortwave Listener's
(SWLs) Shortwave Radio Listening Needs [.]
THE NEXT STEP - LOW NOISE INVERTED "L" {RANDOM WIRE} ANTENNA
Starting with the Random Wire Antenna and incorporating a few
improvements can result in an Shortwave Listening (SWL) Antenna that
has for it's size and placement a better Signal-to-Noise S/N Ratio then
a plain Random Wire {so-called Longwire} Antenna
THREE-TO-READ BY JOHN DOTY :
* The Inverted "L" Antenna 'Shape' lends itself to the Design
Concepts of a "Low Noise Antenna" that has been popularized
by John Doty; consisting of: Antenna Element; Matching Transformer;
Grounding Point; Coax Cable Feed-in-Line; and Radio/Receiver.
