Need advise on increasing power. Quad 5 10M radio

Have you ever used a beam antenna on a base station?

 

It's kind of cool how it works when you rotate it isn't it?

 

Wouldn't you like to experience that phenomena in a tractor-trailer as you're driving down the interstate?

 

It's not really working the way you think it's working

 

When I was running my Volvo 770 with coat phased antennas outside both fairings on the rear of the truck it was like sitting in a beam. Wherever I pointed my truck I could easily talk 60 miles ahead of me and 60 miles behind me no problem.
You will never experienced performance like that out of any tractor trailer unless it is a Volvo 770 or a 780 or in 880 configured exactly the way I had mine configured. About the only way to get that type of distance out of another vehicle would be to put it in a car with an antenna right in the middle of the roof but it would be Omni directional.

 

If I was sitting in a parking lot if I was sitting in a parking lot talking to someone and they were hitting me really good from a long distance away if I rotated the truck 90 degrees they would disappear out of my receiver
