Default Short STACKED Vertical {Tri-Band} BroomStick Antenna [Was: Wire ant question]

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.

BACKGROUND: "BroomStick" Antenna
I have found that an 8Ft piece of PVC Pipe wrapped with
One Long Continious Coil of Wire does NOT perform as well
as the same piece of 8Ft PVC Pipe that is wrapped with
Three (3) Coils of Wire with Spaces between them that are
made from one continious wire.

IMPROVED: The "BroomStick" Antenna is acually a
"Short STACKED Vertical {Tri-Band} BroomStick Antenna".
NOTE: Some like to spell 'broomstick' "BroomStik".

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
