Default The Next Step - The Low Noise Inverted "L" {Random Wire} Antenna - Question Shortwave Listening (SWL) Antenna Tuners - Do You Have An Opinion ?

MK,

Why Don't 'you' Try Answering the Questions Asked ?
- - - vice - - -
Going-Off and advoiding the facts and issues at hand ?

MK - So 'you' are the type of Amateur Operator
who uses one Antenna on All-Bands ?

MK - Your 20-Meter Band 4-Element Yagi might be
Great on the Amateur 20 Meter Band and be 'ok' on
the 22 and 19 Meter Shortwave Bands - But honestly
would 'you' use it on the 60-49-41-31 Meter Shortwave
Bands ? ? ?

For the Shortwave Listener an Inverted "L" Antenna that
was 25 Feet High by 50 Feet Long would be a better
General All-Band SWL Listening Antenna then your Yagi.
Vertical-Up-Leg for 31-Meters = 1/4 WL @ 24.5 Feet
Horizontal-Out-Arm for 60-Meters = 1/4 WL @ 47.7 Feet
Total Length of the Wire Antenna Element 72.2 Feet
= = = One Antenna : Built-It & Rig-It = Enjoy-It )
[ An 'average' size SWL Antenna that can "Fit" InTo
the Urban Backyard. ]

For the Shortwave Listener wanting something a little
Bigger then an Inverted "L" Antenna that was 32 Feet
High by 71 Feet Long would be a little better General
All-Band SWL Listening Antenna - If they had the Space
and the Ability-to-Rig the Antenna Wire that High .
Vertical-Up-Leg for 41-Meters = 1/4 WL @ 31.8 Feet
Horizontal-Out-Arm for 90-Meters = 1/4 WL @ 70.9 Feet
Total Length of the Wire Antenna Element 102.7 Feet
= = = One Antenna : Built-It & Rig-It = Enjoy-It )
[ A 'larger' size SWL Antenna that can "Fit" InTo
the Urban Backyard. ]

Alas, many Shortwave Listeners can only have an
Inverted "L" Antenna that is a little smaller and 15
Feet High by 30 Feet Long would be the best that
they could do for a General All-Band SWL Listening
Antenna - Since that have very limited space and
can only Rig oh-so-high.
Vertical-Up-Leg for 19-Meters = 1/4 WL @ 15.1 Feet
Horizontal-Out-Arm for 41-Meters = 1/4 WL @ 31.8 Feet
Total Length of the Wire Antenna Element 46.9 Feet
= = = One Antenna : Built-It & Rig-It = Enjoy-It )
[ A 'small' size SWL Antenna that can "Fit" InTo
the smaller Urban Backyard. ]
Note - The Par EF-SWL Antenna lends itself to this
'small' Inverted "L" Antenna Rigging and it is only 45
Feet Long and includes the Wire Antenna Element
and Matching Transformer - Just add Ground Rod
plus Coax Cable and you are ready to Rig-It and
Enjoy Listing to your Radios.

* Consider Buying or Building a better Shortwave Listener's (SWL)
Antenna.
Lets Think : Out-of-the-Box {Ready-Made} Shortwave Listener (SWL)
Antennas
WHY - The simple Random Wire Antenna is better than the Dipole Antenna
for the Shortwave Listener (SWL)

MK - Remember for the Shortwave Listener the SWL Antenna
is just-a-means to being able to Listen to "Their" Radios and
Enjoying the Listening Experience.


mk - enjoy being a ham ) -and- i will continue to enjoy . . .
just being a shortwave listener (swl) - iane ~ RHF
