Cascadia/Predator 10k/27" shaft

I would go with single antennae on drivers side, with co-phase set up you will be directional. The reason the majority of us angle the antennae forward is when you are driving the whip will be in a vertical position. Ive been using that attenae on my cascadia for over a year now and have had good results, swr 1.2 and tx and rx 10 miles or better with uniden bearcat 980.

 

Until Kale starts making one with a 48" shaft I would recommend a 7 foot fiberglass whip.

 

10 miles with a uniden 980. Wow. What kind of antennae?

 

Predator 10k with 27 inch shaft mounted on a 2016 casscadia talking to friend on his base station, i have since (as of yesterday) switched to a top loaded 5ft firestick, just wanted to try something different, tx and rx seem to be just as good but static level seems to be less,

 

Sounds like the static you're hearing is radiated RF noise, either generated by your vehicle or just plain ol' RF from the thousands of radios out in the ether. In which case, a shorter antenna with smaller capture area should hear less noise. And as long as you've got more than enough RF output to barely be perceived at the other end, and likewise the stations you're listening to have more than enough radiated power to exceed your RX threshold, then a slightly less efficient antenna will still be acceptable. Once you need longer (because of being out of range for a 5-footer), then I maintain that *any* resonant antenna that's longer than what you have will outperform the 5-foot loaded one. Doesn't matter much whether you've got lots of bug catcher coils littering the outside of the driven element, or just a straight quarterwave whip (assuming it'll fit), as long as it's resonant, the greater the cross section of the active part of the element, the more capture area it'll have (like a larger sail catching more wind on a boat) and less of the RF streaming past your antenna will be missed.

If I really needed to look cool, I'd put up a 108" whip on a metal fender, and make some wraps of colored vinyl tubing to *look* like 20 megawatt coils, just for looks. But that's what I get for majoring in physics in college, too.....

Ive concluded that the static is coming from the steer hubs because the noise level changes with different surfaces like asphalt or concrete, and it will dissapear when I brake or when the surface is wet. I remember reading a post on a forum, may have been this forum, where the individual added small amount of graphite powder to hub oil and it eliminated the static totally, but since I drive a company truck I am hesitant to try that.

 

Run a longer antenna mounted low with the load up as high as possible. This will always outperform a shorter antenna mounted higher.
