sirio pl5000 performer ant. anyone know about them?

More to it than swr,so dont assume just cause you have a low swr that all is perfect..

 

I love my sirio mag mount..Its the 5000..Works great....Just gotta put my radio back in my trk and start useing it again..

 

Performer for a tractor

Turbo 5000 for a car or SUV with a sheet metal roof.

 

Something is off if.you cant.get a lower tune on a mini van of a 1.7 on 26950 and a 1.8 on 28740....
I dont go higher in my pickup than ch 40(27405) or lower than 1 (26965)with my stryker 447hpc2 so im not sure what it will tune as goin higher..On my sirio 5000 mag im pretty much dead on with my r#/x# and swr is no more than 1.2 with my rig expert..
