![]() SWL -Newbies- So Your 'portable' AM/FM Shortwave Radio - Needs an External Antenna for Better Reception For the Newbie Shortwave Radio Listener (SWL) here are a few more easy-to-make and low-cost Antenna Ideas that will work with 'portable' AM / FM Shortwave Radios that do not have an External Antenna Input {Jack /Connection}. They also work well with Radio's with External Antenna Input too. Read - One of the simplest Shortwave Listener (SWL) Antennas that I know of is a Doublet {Dipole} Antenna made from http://groups.google.com/group/rec.r...3eb0cf326d45d1 - - - Guess What . . . Speaker Wire ! This is a basic Out-Side Antenna that is made of low-cost and easy-to-find Speaker Wire. Tip - Transform this Doublet {Dipole} Antenna in to a Windom Antenna {Off-Center-Fed-Dipole} -by- Folding One of the Arms back-on-itself and securing the wires together with Wire Ties -or- simply Cutting One of the Arms in-Half. http://www.dxengineering.com/images/...ndom_Balun.gif http://www.io.com/~maddog/hampix/win...view_annot.gif Read - Another of the Simplest Shortwave Listener (SWL) Antennas That I Know Of..." - The Same Idea Taken In-Side {In-Doors} and Guess What . . . It Is Ready Made ! http://groups.google.com/group/rec.r...bed3e059ec70a3 -cause- It is a simple FM Folded Dipole Antenna that is made from 300 Ohm Twin-Lead. http://www.universal-radio.com/catalog/misc/1268.jpg http://www.prairiepublic.org/programs/images/dipole.bmp http://www.farnsworthelectronics.com...s/antenn14.gif http://technology360.typepad.com/pho...fm_antenna.png NOTE - An old Pair of TV Rabbit-Ears {Portable FM 'Dipole' Antenna} can be 'substituted' for the FM Folded Dipole Antenna : http://groups.google.com/group/rec.r...edc1e05ab1e40a -fwiw- The Rabbit-Ears Work pretty good too. http://www.farnsworthelectronics.com...s/antenn10.gif Think of the Rabbit-Ears as a Pair of Balanced Twin Whip Antennas resulting in about Twice the Signal with No Increase in Noise. http://www.farnsworthelectronics.com...es/antenn6.gif Making the "Connection" for the FM Folded Dipole Antenna to your 'portable' AM/FM Shortwave Radio : * Connect an Alligator Clip to One of the Leads of the FM Folded Dipole Antenna * Connect Rear-Barrel of an 1/8" Mono-Plug to the 'other' of the Leads of the FM Folded Dipole Antenna {Carefully Remove the Tip of the 1/8" Mono-Plug} * Stretch-Out the the Two Top-Arm Elements of the FM Folded Dipole Antenna along with the feed-in-line into the Shape of a "T" across a Window or on an Outside Wall http://kalx.berkeley.edu/recept/images/dipolbld.gif http://www.oldradioworld.de/gollum/dipole.gif * Insert the Rear-Barrel-End of an 1/8" Mono-Plug into the Radio's Headphone Jack * Attach the Alligator Clip to the End of the Radio's Collapsed Whip Antenna * Position the FM Folded Dipole Antenna for the best Peak Signal -or- to Null-Out and unwanted Signal. http://kalx.berkeley.edu/recept/tanttips.htm http://www.wgbh.org/content-download...ion_id=1389567 Read - Modified 1/8" Mono Plug for a 'portable' Radio's Ground Connection http://groups.google.com/group/rec.r...fc3da484634042 http://groups.google.com/group/rec.r...09862a70cf7335 http://groups.google.com/group/rec.r...3ff37c43ddc109 http://groups.google.com/group/rec.r...0ed50fc050ab50 Read - The External Antenna Input for most 'portable' AM / FM Shortwave Radios with 1/8" Mono Jack http://groups.google.com/group/rec.r...72ba6245769bf3 Read - Mini-BroomStick Shortwave Listening (SWL) Antenna -It's- In-the-Window ! http://groups.google.com/group/rec.r...ede4812d2bd230 shortwave radio listening -swl- keeping it simple and practical -cause- it is about listening to the radio - iane ~ RHF {pomkia} |
