Rate my setup

Oh yes, I forgot about the difference in RF grounds on trucks today. Thanks for the reminder.

 

Just to clarify, I agree there are reasons when tilt is needed. I was not trying to bust chops. I simply hate the thought of someone tilting without knowing why. It does affect the radiation pattern

I've told the story here of my beloved Cherokee County GA Public Service being involved in a radio interference dispute with Clayton County GA. The FCC instructed Cherokee County to tilt their antenna 2 degrees to avoid stepping on Clayton. The ruling is still searchable via Google

Because at highway speeds its sits at darn near 90 deg straight up....
A 102" on a 10" riser has tons more flex than his predator..
Now whennparks my pattern will change drastically..I also gotta deal with reflect off the truck to.....Cant compare an apple and bananna and expect the same results..

 

For those who know,no they are not picking on ya..
If anything i woulda gone with a shorter base shaft and stood them up more and allow the whip to bounce along the low clearences stuff you drive under...Or buy 4.5 ft skip shooters orrrrr quick disconnects for the 10k's....Haven those 10k antenna as a single or duel set up is nice an an all but coulda saved some $ and grabbed two top loaded antenna and half the cost which would cover the quick disconnects and STILL got great range....
Now go do some rf bonding and it will help some more..

 

You looking good.

 

Why not run a couple Wilsons? They're very flexible, durable and function quite well. You can also easily replace just the whips cheaply if you beat one up too bad. I've put mine through years of torture and they're still kicking.

 

Problem is you're jamming a square peg into a round hole by trying to make them work under these conditions. They aren't a good choice for your application.
