Single antenna or co -phase

I debated this exact issue this past week and opted to stay with a single setup. Nothing really to gain with duals.

 

Dual antennas work, but try to keep about 9 feet of each other.
(1/4 wavelength of 27mhz is about 9 feet)
When running Duals - the antennas increase their gain forward and aft of the truck at the expense of some power to the sides... the signal to the side is about 1/2 an S unit lower....

Ensure you use a good co-phase harness designed for 27MHz CB Radio. These are usually two lengths of 75 ohm coax joined to form a single 50 ohm connection to your transceiver. Keeping the two feeder lengths exactly the same length is very important if you want to maintain some kind of symmetry of your CB Radio antenna pattern around your truck....
Of course I think dual antennas not only perform better but look great.

Looks are all that matters right?

PS. If duals are not installed correctly (cable choice and length and antenna placement) then they will not work as optimum as a single antenna can.

 

Must have one hell of a super radio to be needing an antenna like that...

 

and i have allways been told you need to have a 18 foot coax not sure if that is true or not

 

NOT TRUE coax dosn't care how long it is

 

18' of good coax (not the thin black) probably best to get it off a c.b tech because they solder the ends real good for the same price as a cheapy. Lace it like a figure 8 or string around the corners of the cab........ 2 antennas act like a garden hose shooting in 2 directions vs a single stream with one direction, however, it's believed to be able to hear better with 2 but who would want to.

 

define good coax
