I have a Realistic DX 160 shortwave reciver and have a question about the
antenna I am using with it, now I am using 15ft to 20ft of 16ga wired rapped around a 12ft to 14ft copper pipe is that a good antenna to use with the reciver. If this is not a good antenna what antenna should I use that I could buy or build easily. Is the Broom Stick antenna any good and would it be a better antenna than I am using now. |

DJboutit,
QUESTIONS: ? Is this Insulated Wire or bare wire that is wrapped around the Copper Pipe ? ? Is this piece of Copper Pipe part of your household water systems ? NOTE: This Copper Pipe may be a good Grounding Point for your Radio Equipment and Antennas. FWIW: Sounds like you have a 12-14 Foot piece of Copper Pipe for an Antenna. CONCERNING THE BROOMSTICK ANTENNA: [ Less Wire and Better Results ] In general a Copper (Metal) Pipe would NOT make the best core for a helically wound Antenna. THE BETTER IDEA: Is to use a piece of 8Ft to 12Ft PVC Pipe who's body is made of insulator type material and that has an Air Core. WHAT TO DO: Wind your Antenna Wire Element around this piece of PVC Pipe to form your Helically Wound Vertical Antenna. NOTE: This type of Helically Wound Vertical Antenna is commonly called a "BroomStick" (BroomStik) Antenna and was popularized by Arnie Coro the Host of DXers Unlimited on Radio Habana de Cuba.

READ: Understanding the "BroomStick" Antenna and its Coil http://groups.yahoo.com/group/Shortw...na/message/415 IMPROVED: The "BroomStick" Antenna is acually a "Short STACKED Vertical {Tri-Band} BroomStick Antenna". NOTE: Some like to spell 'broomstick' "BroomStik". READ: Tri-Band "BroomStick" Antenna http://groups.yahoo.com/group/Shortw...na/message/420 Materials Needed for Tri-Band "BroomStick" Antenna: * PVC Pile = Eight Foot Length of 1.25" ID (1.5" OD) * Insulated Stranded Wire = Forty Feet (40 Ft) - RadioShack Catalog # 278-1218 - - Ninety Foot (90Ft) Spool of Stranded, 22 Gauge Wire. - RadioShack Catalog # 278-1220 - - Fifty-Five Foot (55Ft) Spool of St4randed, 18 Gauge Wire. * Black Electrical Tape = One Roll. [Secure both Ends of the Coils with 4-5 Wraps of Electrical Tape.] * Top Hat = "9-12" Pie Pan (Optional) DESCRIPTION: Tri-Band "BroomStick" Antenna: [ From Top ~ To Bottom ] {Actual constructon is done bottom to top.} * 'Optional' Mechanical "Nut-&-Bolt" TOP-HAT Connection at 1" from the Top. * Third Vertical Separator 9-10" * Top Coil: 12 Turns @ 1/8" Spacing - Surface Length of Coil 1.5" (This Coil has 4.7 Feet of Wire Wound in it.) Note: Use a 12" piece of Hook-Up Wire as a Coil Spacer Sleeve to Form this Coil. * Second Vertical Separator 16" * Middle Coil: 24 Turns @ 1/4" Spacing - Surface Length of Coil 6.0" (This Coil has 9.4 Feet of Wire Wound in it.) Note: Use a 12" piece of Zip Cord as a Coil Spacer Sleeve to Form this Coil. * First Vertical Separator 26" * Bottom Coil: 48 Turns @ 1/2" Spacing - Surface Length of Coil 24.0" (This Coil has 18.8 Feet of Wire Wound in it.) Note: Use a 12" piece of TV Twin Lead as a Coil Spacer Sleeve to Form this Coil. * Bottom Vertical Separator Stub 13" * Mechanical "Nut-&-Bolt" Lead-In-Line Connection at 1" from the Bottom. .. ..

Run a wire outside to a tree or whatever, or around the house in the attic or along the ceiling. The longer the better in general, but 50 ft is good for a start. A 50 ft wire should be better than a broomstick. MK |
