Single antenna or co -phase

Not all the time.

 

The reality is, how much range do you really need? Will it make a hill of beans of difference if you can hear some loudmouth saying "Shut up, stupid" for an extra mile???

 

I don't get what you are driving at?

The reality is that one antenna can work and does work better than two.

A phased antenna array - which two antennas are - doesn't always mean the effectiveness of the radiation from the system. More things make the system work, the antenna are just a part of it, 1/3 of it.

Don't know, frankly recieve is the easy part.

 

Well depends on the car/trk its goin on..Big trks have alot of fibreglass,glues,insulators that stop a rf bond...So without bonding its gonna suck no matter....
Either way i would go with the one ant cause the diff in two vs one in re to range is not a big difference....Biggest diff is either front to back or around your car/trk and expence with extra work to maintain...

 

Doesnt make much of a diff with trk cabs/sleepers being mostly of fibreglass...

 

the only part of my volvo 780 cab that's fiberglass is the roof.

The only part of my prostar that's fiberglass is the roof.. even the cab extenders are metal

 

That's interesting, I thought the hoods were fiberglass too. Unless these are older trucks.

 

Naw the newer stuff is all fibreglass to..

 

i said cab not hood

 

depends on the truck manufacturer...
