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..
Update: Since I was going back out west I did have my antennas put in a more upwards position and got the SWR's reset in that upwards position. Since my trailer had the air pods I could bypass the safe racks and the silos out west are plenty big enough to fit through. Then we got a new hire who whined and cried about not being in physical shape saying he's unable to open hatches. The company decided that he needed the air pods more than me. So back to the safe racks to climb up and open hatches I go since fat old cry baby got my trailer. I just simply asked my operations manager what happens when he gets on location and has to run 60' of hose underneath the conveyor to the silo on the other side. I've crawled underneath the conveyor dragging 20' of hose many times. Is he going to be able to do that in all his PPE on location if it's too hard to open a hatch? Anyhow, the inevitable happened and my antenna hit the safe rack. Fortunately it appears that the antenna survived the strike. It's a tough antenna. The damage was to the mounting base which bent. That's a whole lot cheaper than the antenna. None the less my SWR's are screwed again. So I've uninstalled my antennas and will just be without a CB until I get back up north (no CB shops around here) then they will be returned to the despised angle and have the SWR's set that way again. Either that or just buy some cheap Hustler antennas until I can get air pods again. Apparently I'm on the top of the waiting list for the next air pods equipped trailer. Will probably be getting my old trailer back after dude starts running hose on location unless he's doing the local wherehouse runs in which case I will get my trailer back when he realizes how cheap those payouts are.
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.
