I wish it was easy to model a vehicle. I have done some testing with a friend. My puck mount preformed as good as a mag mount with a counterpoise..... Im starting to believe antennas being 6' off the ground really dont make much difference in mounting. I have also done blind antenna testing (on a hilltop) switching multiple antennas many times. The winner...... A 5' Firestik....lol I give up what ever tunes works for me!!!
