Picture of Simple CB base station antenna
This is a simple base station CB antenna You can make in 30 minutes out of a bit of PVC pipe and fittings, some wire and a SO239 coax connector and a piece of coax to connect it to your radio. You should have a 1.5 SWR on this. You should be able to build this for about 10 to 15 dollars.

Hi rbodell

Why do you suggest 2-Pieces of 8'6" 12 or 14 gauge electrical wire. Where does the other one go?

2 PCS 8'6" 12 or 14 gauge electrical wires

1- Strip back 1/8 inch insulation on wire and solder to center of SO239

2- Solder electrical connector to end of second wire.


Insert wire that is soldered to SO239 into hole in cap then mount SO239 (radiator)
to cap with screws and a little sealant. SECOND WIRE (ground) ---->Put eye of other wire under one
of the screws. Tighten and put a little sealant over screw with wire
under it.
5- insert wire under screw into hole on bottom of T (see red wire in picture) and out the bottom of the T
6- Insert wire soldered to SO239 in T and out the to 3/4 inch hole in top and glue cap to T.
