RO90,
How High is the Concrete Clothesline Pole ? * One Short 6.5Ft to 8Ft Pole for an Unbrella Clothesline * Two Short 6.5Ft to 8Ft Poles for a Short Low Clothesline * Two Tall 10Ft to 16Ft Poles for a Long High Clothesline Does this appear to be a pre-manufactured pole that is re-inforced with iron or steel wire and/or bars builtin to its Core ? In general re-inforced concrete pole would NOT make the best core for a helically wound vertical 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/SWL-AM...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/SWL-AM...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. NOTE: Total Wire required for this BroomStick Antenna is 40 Ft. Short STACKED Vertical {Tri-Band} BroomStick Antenna http://groups.yahoo.com/group/SWL-AM...na/message/755 iane ~ RHF ..

Hi I bought this RadioShack antenna kit and I have this concrete clothesline pole just outside my shack. I was wondering if it would work to wrap the insulated wire (50 feet) around and around the concrete pole ? Thanks .. |
