Dipole Antenna for 10 Meters and CB
from Ryan St. Arnold - KCØJEX
This antenna makes a a great antenna for 10 meters or CB, very
low cost to build, and highly efficient.
Materials:
18 feet of insulated #12 Solid Copper Wire (Uninsulated or stranded
should also work, similar wire)
2 End and 1 Center Insulators
Nylon or similar rope to hold antenna up
Coax - your choice
Directions:
- Take the 18 ft. piece of copper wire and cut it
exactly in half
-
Take about 1 1/2 feet of one end, and wrap it around the insulator a
few times, leaving about 3/4 foot or so for tuning. (Let it hang, see right
picture)
-
On the other end or the half piece, wrap it once or so around the
center insulator leaving about 4" for the coax connection.
-
On the wire just wrapped around the center insulator, strip about 1"
for the coax connection.
-
Do the exact same to the other 9 ft. of wire.
-
Now you should have a dipole about 16-17 feet long, connected in the
middle via a center insulator
-
Tie some rope on the other hole on both end insulators, enough to tie
around a tree, or pole.
-
Connect the coax, as seen in the left picture. No connector is needed,
cut the braid and center conductor of the coax exactly the same length, about
2", and wrap one around one wire, and the other around the unconnected piece
of wire.
-
Put electrical tape over these to avoid weather damage, and to keep
them on the wire.
-
Run the coax about 90º parallel to the dipole, until it hits ground or
roof.
-
Run the coax in house, install PL-259 on unused end, and hook up to
SWR Meter which is connected to 10 Meter transceiver or CB.
-
Transmit on the radio and check the SWR, if happy with it, leave it.
If not, go out to the dipole and trim an inch or so equally of each end of the
dipole (hanging wire). Do this until happy with the
SWR.
E-mail me with any questions, I will be more than happy to help
out.
