A Dipole antenna is simply two wires, each 1/4 wavelength long, fed in the center usually by coaxial cable. Typical Dipoles are horizontal. A 1/4 wavelength on the 27 Mhz frequencies is about 108 inches or 8 feet so you would need to have it be a half wave or 16 feet long. With wire antennas, you want to support it at least that same 1/4 wavelength above any objects. IF you build it Horizontally it will work, but most of the folks you will be talking to are vertical and you will have somewhat less signal to and from them. It will work. If you can support that 16 foot antenna vertically without it being next to or close to anything especially metal, you would be better off. I've done it using a vertical plastic pole. See this site. http://nathan.chantrell.net/old-stuff/radio/radio-scanning/how-to-make-a-simple-dipole-antenna/ The purely straight line unit is 75 ohms and you usually need 50 ohms for a CB. You can achieve this by putting it in an Inverted V configuration. check out this youtube video. http://www.youtube.com/watch?v=fyOWRTWdDKM

You can buy one from ebay, I just saw someone selling them really cheap, but usually they are $30 I made one out of an extension cord one time and it worked, just a 9 foot heavy duty extension cord and cut off the female side and spread the wires out and trim wires a little at a time for the best SWR, it was as good as the one I got from ebay. Here is the link for the cheap dipole on ebay if you just want to get one already made and cheap http://www.ebay.com/itm/NEW-LOWER-PRICE-2-meter-2M-Half-Wave-Amateur-Ham-Radio-Dipole-Antenna-/121228683404?pt=US_Radio_Comm_Antennas&hash=item1c39cae88c
