One alternative: get a new girlfriend.

Sorry. I couldn't resist.

ADVICE on aerials for 5.680
 

I live in an apartment complex and can't put antennas up. So, I hooked a
wire to the downspout and run it under the window - works very well. It's
prolly only 30 ft at the most but it is straight up and down. If there is a
tree not far away, tie a stone to the end of as long a wire as it takes and
chuck it up into the highest part of the tree (or do the same with a
slingshot). Use small diameter wire.

These ain't terrible either. Work OK with 10-20 feet of wire.

I should clarify: I hooked the wire to the bottom of the downspout. You
could easilly use a small alligator clip. Make sure it has electrical
contact with the metal in the pipe, and that the pipe is metal.

Hi All,

im looking for a HF antenna that will be ok for listening to Kinloss Rescue
i used to have
a long wire at my old property which was great but now im with my girlfriend
she does not fancy a 100 ft long wire from on side of the house to the other
please could somebody advice me of good alternatives So what hf antennas are
there apart
from long wires that i could have both advice on indoors and outdoors would
be great.

Once again thankyou for all your hard work and help.

The Slinky Quarter Wave Length (1/4 WL) Shortened {Loaded} Vertical Wire Antenna
 

Jonny in the UK,

Check-Out - This "Frequency Wavelength Calculator"
http://www.csgnetwork.com/freqwavelengthcalc.html

The One Wave Length Measurement for 5.680 MHz
is 173.24 Feet or 52.84 Meters.

A Quarter Wave (1/4 WL) Length Vertical Wire Antenna
would be 43.31 Feet or 13.20 Meters.

THE SLINKY QUARTER WAVE LENGTH (1/4 WL)
SHORTENED {LOADED} VERTICAL WIRE ANTENNA :

A "Shortened" {Loaded} Quarter Wave Length (1/4 WL) Vertical
Wire Antenna : [Using One Long Bottom Loading Coil ]

Requirement - This Shortened Quarter Wave Length (1/4 WL)
Vertical Wire Antenna Requires a Vertical Support-Point of at
least 25 Feet and up to 45 Feet high above ground level; with
about 27 to 33 Feet being about the right height.

First use a Coax Cable Feed-in-Line running out along the
ground or under the ground from your Radio about 45-50 Feet
(15-17 Meters) from the House to the Base of the Antenna.
* If space is limited 20-25 Feet (6-8 Meters) will do OK.

Use a Four to Eight Foot (4-8 Ft) Ground Rod at the Base
of the Vertical-Up-Leg of the Antenna.

Use a standard Full Size Slinky as the Variable Loading Coil
for the Quarter Wave (1/4 WL) Length Vertical Wire Antenna.

NOTE - The standard Full Size Slinky has about 100 Turns
with a Diameter of 2 3/4 Inches and a Circumference of
8.64 Inches for a Total Wire Length of 72 Feet.

How Long Does a Slinky Get ? - I Calculate that the Optimum
"Stretched-Out" Length of a Slinky would be about 22.9 Feet.

Connect {Solder} a 23 Feet (7 Meter) piece of Insulated Stranded
Copper Wire to one end of the Slinky.

To the free-end (Far-End) of this Copper Wire tie a 50 Foot piece
of Nylon-Poly Rope to Rig the Wire Antenna Element.

Connect (Solder) the free-end (Bottom-End) of the Slinky to
the Center {Inner} Conducter of the Coax Cable.

Connect (Clamp) the Outer Shield of the Coax Cable to the
Ground Rod.

Rig the Nylon-Poly Rope to your Upper Vertical Support and
Stretch-Out the Copper Wire up to this Support-Point.

Note - The Radio-End of the Coax Cable should have a
Coax Cable Connector to 'fit' your Radio.

Connect the Coax Cable to your Radio and Tune to 5.680 MHz.

Use the Nylon-Poly Rope to Shorten or Lengthen the Length
of the Antenna to Receive the Maximum Signal {best sounding}
on 5.680 MHz.

Note - If the Upper Support-Point is only about 25 Feet high :
Then the Far-End (Top-End) of the "Insulated" Copper Wire
may go through or over the Upper Support-Point and be angled
down at about 45 Degrees from the Vertical Wire Antenna.

Trimming the Wire Antenna Element - If necessary the Copper
Wire Antenna Element may be Trimmed {Cut} from the Far-End
by Three Feet (3 Ft) or One Meter; and then the Length of the
Antenna may then be Adjusted for the best signal on 5.680 MHz.


hope this helps - iane ~ RHF

Dipoles are good. You can put one in an attic without much problem, you can
bend the lengths around corners etc. Be creative. I'm sure you will get a
good signal with adequate height.
