A competition amp on 14 volts can run all day with an SWR of 1.5-1 or less. A stock Texas Star or Palomar need 2-1 or less because since they have 1/2 the output of a similar comp amp. Drill a 3/4" hole in that mini van and get a Wilson 5000 roof mount.
If course moving a magnet mount radically on the roof is going to get slightly different swr results.

yes moving the magnet does seem to change the swr dont know why.. really just wanna
know if having the antenna more towards the rear then in center will hurt/hinder
its performance.the amp will be texas star /palamar type.thanks
