Default WHY - The simple Random Wire Antenna is better than the Dipole Antenna for the Shortwave Listener (SWL)

JP,

* "proper elevation and orientation"
There is the thing that makes the properly built Amateur
Dipole Antenna the better Transmitting anf Receiving Antenna
for it's designed Frequency and Target Signal Area.

AMATEUR DIPOLE ANTENNA :
The Amateur Radio Operator who knows his craft will take
the time and spend the money to Build and erect the Dipole
Antenna in the right place and at the right height for it
to perform optimaly for it's designed operating Frequencies.

OOPS - The Shortwave Listener will often simple 'hang-up'
the Dipole Antenna between two relatively low supports
and expect miracles.

RANDOM WIRE ANTENNA [LOW NOISE INVERTED "L" ANTENNA] :
NOTE - This is why the simple Random Wire Antenna configured
as an Inverted "L" Antenna is usually the better "Throw-It-Up"
Antenna for the Shortwave Listener who wants an All Band
(AM/MW and Shortwave) that is an Omni-Directional Antenna
to Hear Them All . . .

TIP - The lay-out of the Inverted "L" Antenna lend itself to
the design concepts of the so called Low Noise Shortwave
Listener's (SWL) Antenna that were popularized by John Doty.

C.E.,

I didn't mean to imply that an HF antenna would normally
transmit farther than it can receive, only that a random
wire can sometimes outperform it on the receive-end.

This can happen even when listening on the transmitting
antenna's resonant frequency.

Under average circumstances, a dipole at proper elevation
and orientation will outperform a random wire (tx or rx).
