Question:
1)Receive Only with Indoor Antenna/ Longwire for AM thru full Shortwave:
Has anyone tried a Passive Tuned Loop at the END of the longwire then placed in a window?
This would have a tuner like used on AM Passive Loops but be Shortwave Tuneable (with a Bypass )-possibly with multiple taps on the Coils or Concentric ?
It could be used at the End of the Longwire in a Window-
OR as the final stage right before Receiver fed from the Longwire and plugged directly into the Ext Antenna ...
Both above ways would be plugged in to Ext Antenna of Receiver
'Tuner' would have a bypass also.
Theoretically the Preselector Tuning Freq would have more effect placed right before Receiver...BUT may be better at opposite end...Window Placement or 'Tuner OFF '.
Since these work well for AM Broadcast- using a larger loop for SW / All Bands might work also IF there are Harmonics of the ' Waves ' [ frequencies ] you are trying to catch.
Does the Active 'Magnetic' Effect increase the Resonance more ( like a Wellbrook ?)
Could a Passive Version work well also ?
Possible that this would increase Antenna Gain without increasing noise ?
Could it be only 2 feet or so in diameter ?
What do you Antenna Wizards think ?
