just for the record

In my experience, the radios I hear the furthest are stock cobra 29's with Factory antennas on new trucks (metal trucks only)
or Marks customers.

 

Keep in mind, most trucks are co-phased from the factory for a reason

 

I have much better luck with a steel cab than an aluminum cab.
For that matter I have better luck with plastic body trucks than aluminum body trucks

 

60 miles out of a Volvo 770 or 30 miles out of a Peterbilt 379. Which would you rather have? I'd take the Volvo 770 any day of the week

 

My next choice would be 40 miles out of a Peterbilt 387 with a plastic body

 

I would take a Freightliner Cascadia over a Peterbilt 379 simply because I know I could make it talk twice as far

 

"after hearing so many speak for so many years about how this guy or that trick is an end all solution, it is hard not to speak up."
At no point in time have I ever said one solution is the right answer for all vehicles.
common sense ( which is in short supply)
Dictates all vehicles have different issues.
"I would rather have an educated person go into a shop and buy things that work than to depend on those who only care about selling something to just sell it and make a buck."
At no point in time have I ever recommended for people to go to someone who only cares about selling something to make a buck. Quite the opposite actually.
I only recommend that people educate themselves about amplitude modulation and develop the knowledge necessary to discern whether a potential "tech" has the capability to produce a waveform like the one in this picture before throwing away their hard earned money.
Your cynicism and failure to recognize the importance of the contents of this picture
combined with your statements like "lots of people can do that work" don't help anyone make an educated decision but rather muddy the waters making it more difficult for forum members to make an informed choice.

 

"But my point is that the truck design is pretty much a static peice, the materials used and the location of the materials are dictating the rf profile of the vehicle more often than not"


Here is another prime example of muddying the waters without providing any useful information which might help someone.
