Great Little Antemna  Time owned: more than 12 months
I have been using this antenna on the roof of my Subaru Forester for over 10 years and have been very pleased with its performance on both 2M and 440. I also have a Diamond NR770HNMOB, which is almost 3 times its size. With side by side comparison with users on fringe repeaters, there is almost no difference! Incredible performance!

Requires good ground, then works great  Time owned: 0 to 3 months
I use a trunk lip mount on my Subaru BRZ, and bought this antenna for its low profile that wouldn't make my car look like an R/C toy. When I first installed it, performance was terrible. My radio even shut down when I tried to transmit on high power. I investigated and discovered that I had not properly grounded my trunk lip mount all the way through the paint to bare metal. which the antenna's documentation is very clear is required. That was entirely my fault, not Diamond's. I reattached the mount, making sure to screw through the paint to bare metal, and instantly the antenna worked perfectly on both 2m and 70cm, from one end of each band to the other. I can get into and receive all of my local repeaters, up to and including on high power.

Diamond is serious that this antenna absolutely requires an excellent ground to function properly. They are absolutely correct. You can't use this with a magmount, or a bad ground. But as long as your ground connection touches bare metal, you should be fine.

10 years and running  Time owned: more than 12 months
I bought this over 10 years ago and
'temporarily' installed it on a mag
mount on the roof of my wife's minivan.
I never did get around to doing
a permanent install.

So over 10 years and 200k+ miles later,
it's still working great. The SWR is
still good and I'm happy with it.

One Great Little Antenna!  Time owned: more than 12 months
I have been using the Diamond NR72BNMO on my Pickup Truck for a couple of years now. It works great being able to get into several local 2 Meter Repeaters and I am able to get into a 2 Meter Repeater with it from about 35 miles away on a regular basis! I am able to get into our local 440 Repeater too, although there is limited activity on 440 in our area. The short length makes it perfect for getting into my garage without having to get out of my truck to either remove it or fold it over as with other larger antennas.

Excellent antenna  Time owned: more than 12 months
Drilled a hole in the Jeep's cab where the roof light is. Except for banging on low hanging beams in some parking lots, it's been working like a charm. Due to pave paws we don't do much 440 out here anymore. Wish they made a 2m only version.
Have used this from the "fringe" and it always gets my signal out.

Great Low Profile Roof Mount  Time owned: 6 to 12 months
I recently installed my first "true" roof mount antenna, i.e.:drilling the hole in the roof for the NMO mount. I first used my existing Larsen 2/70, which, by the way, is an excellent antenna. Everything was fine until my first parking deck. No physical damage, but the incessant banging had to go. Enter the NR72BNMO. What a little workhorse! I can't tell any difference in signal strength from the taller antenna. I know I'm getting some advantage from the ground plane provided by the center mount. I highly recommend this antenna to anyone who spends any amount of time in parking decks or other low-clearance areas. The stealthy "cellular" look isn't bad either.

I have 2 of them  Time owned: more than 12 months
I liked this antenna so much that I bought a 2nd one. I have had mine for nearly 3 years now and I can honestly say that it's a great antenna! I consistently hit repeaters more than 50 miles away.

Works great for size  Time owned: 6 to 12 months
Fits on top of my Sienna mini van and fits in the garage which is great. Have clipped it twice by accident and it bends. Just bend it back. Its quite stiff. Its also nearly invisible, very stealthy. I got an antenna analyzer and tuned it slightly to get SWRs below 1.4 on both bands. final position is about 1/8" from the shortest setting. Pops off easily for the car wash too. I have it mounted towards the rear of the roof and it seems a little directional in the forward direction.
