Single antenna or co -phase

Obviously there's not a radio with "truckin radio" printed on the front. It's metaphorical for the use you put it to. Some times you have to hold their hands a little. Forgive them for they are stuck in a box

 

Since I'm considering co phase can you define "gets out"? Like how far

 

Hear hear. In the last 10 years the FCC has handed out 12 fines to ham users that have ignored multiple warnings first. 12.. In 10 years. None of them cb. They don't give a ####.

 

Dont bother..More cost,more hassel for no real advantage....
Only diff is transmit pattern.....One ant makes a omni directional pattern and cophase just doest its best work from front to back of the trk..

 

It only makes a omni directional pattern if it on top of the vehicle. Things like the roof if the truck and trailer block part of the signal

 

Well it wasnt said unless further back what its goin on but still....Its still more work,bigger cost,more maintaince....
It only blocks a small portion of any tx/rx..

 

Here's my take on dual vs. single antennas, coming from the son of an electrical engineer who was a radio tech during the big war, and who understands basic radio theory:

Probably 95% of dual antenna setups are not 'tuned', and therefore the second antenna is often fighting the first antenna in certain directions. Even when properly tuned, truck antennas are dynamic and the motion of the antennas in the wind will pull them in and out of phase. Multiple transmitters and receivers is a great idea for FIXED land antennas, but not so great for flexible antennas. For that reason alone, any dual antenna setup is for nothing more than show. If you like the LOOK of dual antennas, go out and buy a couple, but only run the coax to the one on the driver's side.

 

Well since I have a mobile set up co phase may be advantageous since it may help get out in front a little better and I don't have nearly as much need for side to side. Is that a fair assessment?

 

No, it doesn’t work that way, sorry.

 

Actually, you have it backwards. If 2 antennas are PERFECTLY synched, they will project further in the direction of a line going through both antennas. So, that means if you want to project further UP the highway, you need to place your antennas in a line the direction you are travelling. Mount one on the center of the grill, and the second at the correct distance away on the roof of the truck, or maybe off the back wall of the sleeper. Mounting them on the mirrors means you are reaching further out into the communities on the left and right of you that you are passing....

Another alternative is having THREE perfectly-synched antennas; 1 on each mirror, and a third on front of the hood. This will project in 2 different directions, namely one 30° to the left of straight ahead, and one 30° to the right. This would work pretty good, even on curvy roads....
