ok guys, whats the best mobile scanner antenna you can get? NMO type mount, 140 thru 860?
LOL! Come on, Stevo! You're here everyday and you haven't seen this question asked at least two dozen times in the last month? You know better than that! :lol:
This gets talked to death with nothing ever being settled. And there is no "best", only what is best for you and your circumstances, which you don't tell us anything about. The best NMO on 800 may suck on 150. The best NMO mounted in a body hole may suck when on a mag mount. There's no way to know for sure what is best for you until you try them all. And most people don't even need "the best" to hear everything they want to hear, nor would they even notice the difference between "the best" and what they have.
That said, the conventional wisdom is that the top three best performing NMO all-banders are, in order of rating:
1. Austin Spectra
2. Comtelco Maxrad BMAXSCAN1000
3. Larsen 150/450/800
The performance difference between the three is noticeable, but not huge. And the superiority of one over the other varies with the band you are listening to. If you don't need low band, the Spectra isn't really worth the extra money over the other two. The Maxrad is usually the cheapest of the three, and is also the most widely available, smallest, and most discreet. Probably the best all-round choice, all things considered.
There are several other antennas that are top performers, but are not NMO mounted.
If you're into drilling holes, then you'd actually probably be best off using two different antennas, one for UHF/VHF and one for 800. That will get you better performance than even the best all-band antenna.
