fender bracket NMO mount -or- lip mount?

Surprisingly, it doesn't lean that far back.  I haven't gone faster than 60 or 70 yet though.  I'll be driving 700 miles on Sunday.  Remind me to let you know how it went.

<< The whip on the Larsen NMO2/70B seems small and looks like it would lean back at highway speed, How does it hold up at speed?>>

At 70 mph there is less than a couple of inches of lean. The whip is rather large in diameter for its length and there is little wind resistance.

<< I assume I will need to seal up the bottom of the NMO assembly where the coax attaches.>>

The easiest thing to do is simply spray two or three coats of PlastiDip on the underside.

   "Which is preferred? A vehicle specific fender/hood bracket, or a SO-239 trunk lip mount used on the hood as shown in the attached picture? "


    In my opinion,  the  mount that actually 'screws' to metal for support would be electrically better;  however, the Diamond type clamp mounts you point to are pretty physically robust and work well for numerous hams I know.

    But personally,  I prefer the very low profile type lip mount made by Antenex at:

    In either case,  if you are talking VHF/UHF, the Motorola NMO type mount is the superior antenna base to have on whatever type base mount you use.  Good luck.

Is there any significant difference between the Larsen NMO2-70BK & the NMO2-70B?
I see that the coax cable is included with the BK model. The BK model is $125 & harder to find for sale.  The nmo2-70B is around $60. Is there any good reason to hunt around for the BK instead of the B plus a nmo connector & some good coax?
Thanks!
