Spent some time today thinking about NGP antennas in the mobile environment and seeing I have no experience with them I cant help but wonder if they are really any good, or are they basically ( Something is better than Nothing ). I'm finally going to get a new aluminum cap on my ( New to me ) truck ) this coming Wednesday, and it will be time to think about a new antenna placement mod to the cap. Keep in mind I'm sort of a Die hard, Hard Head about the antenna is best kept in the center of the roof line for best signal radiation pattern. That's why I went with a aluminum cap & I'm also a metal fabricator, so I'm up to modifications. But I think it would be easier to design a lay down mount ( on the side of the cap ) for a NGP antenna for the times of putting the truck in the garage on a lift. So I ask the Pros ( Are those NGP Antennas worth considering or a waste of time & money ) ??????????
