Good to Go!  Time owned: more than 12 months
I've had the same antenna on my last 3 vehicles (2 NMO mount and a mag mount on the 1st one). No complaints still works and looks like it did when new.

15 YO and like day1  Time owned: more than 12 months
Got this one over 15 years ago, It has been moved from car to car and still works as well as day one..The N.C. Hi-Patrol has been using them(Low-band vers.) forever. And-they WILL handle the 200 watt rating. Larsen is the Astron(pwr-supplys) of antennas.

Makes great ground plane antenna too!  Time owned: more than 12 months
I just took an NMO150 antenna and mounted it on the Larsen ground plane kit. Not only is this the best mobile antenna, in my opinion, but it makes a great weather resistant antenna for mounting permanently high in the air. If you need a light weight, very wind and weather resistant gain 2 meter antenna for home use, pick up one of the Larsen ground plane kits and mount an NMO150 5/8 wave mobile antenna on it. The wind won't hurt it, and it makes the best and most rugged 5/8 wave ground plane antenna you can buy.

Great Antenna  Time owned: more than 12 months
These antennas are the gold standard of communications. I have installed hundreds of these for decades. The original ones were silver plated for lower resistance. I can count on one hand the number of failures, all of them mechanical from smacking something that was hanging low. (Okay, one that the whip wrapped around a car wash brush that tried to pick up the car by the antenna, glad it was not my car.)
This antenna was the standard of the Colorado State Patrol for many years after numerous range and gain tests.

Simply Outstanding  Time owned: 3 to 6 months
Based on other eHam reviews of the Larsen NMO-150, I purchased the NMO-150B from AES Orlando for my Silverado to support a new 65w Icom IC-2200H. Not only does this antenna fully live up to it's eHam reputation, it's hardly even noticeable in black.

Great performer, highly recommended, would buy another without hesitation!

From trash to treasure!!  Time owned: more than 12 months
Believe it or not, I found my Larsen NNO 150 on the ground behind a trash dumpster. It was 20 years ago and I was a gung-ho volunteer fireman and college student. Being a poor college student, I was not too proud to pick up a "piece of junk" someone had thrown away and I needed a good antenna for my mobile scanner for my volunteer fire-fighting service/hobby. I cleaned up the light rust on the L-bracket mount and soldered some new coax to it and and mounted it on the bed of my truck. It worked great! I suspect it had been used for a business band radio in it's previous life before being tossed in the trash. That's another sign of a good product....when you see it used in commercial applications. I have seen thousands of these antennas used on business radio installations as well as public service vehicles for police, fire, EMS, forestry, etc. A short while later, I got interested in ham radio and got my tech ticket. Well, I then trimmed the whip a little and tuned it up for 2 meter use and proceeded to use that antenna for the next 10-12 years. It was awesome! It was always very flat, had a super long range and was very durable! It did eventually wear out and I had to retire it when the threaded brass mounting ring inside the base coil came loose and the antenna would no longer stay put on the mount. I still have it and might try putting an epoxy of some sort in there to fix it and see how much more service I can get from it. I have tried some other brands. The little MFJ cellular lookalike dualbander magmount did OK for a $20 antenna. I had 2 Lakeview dualbanders that were larsen copies. Both of those were junk. Was considering trying Comet and/or Diamond, but after reading hit and miss reviews, I plan to go with what has worked for years.....Larsen!! The tough decision will be whether to go with a dualbander or 2 singles and a duplexer. That old NMO 150 was so awesome, it is really hard to resist so I am thinking about spending the extra dough on the 2 singles and duplexer. Buy a NMO 150. You'll be glad you did and so will the guy who gets it after you are done with it!

better than ever  Time owned: more than 12 months
I started using Larsen products 40 years ago when it was the Old Man and a small crew putting them together from gray tubing and epoxy in Vancouver. I still have the first ones I bought! This latest incarnation is more durable and long-lasting than ever. Nothing left to weather or leak (although they aren't as "pretty" anymore). The one piece base coil and a Mylar label last a good long time. I miss the old shop but Radiall/Larsen is very good with customer service. Parts are never a problem.

Commercial grade  Time owned: more than 12 months
I have used many mobile antennas over the years, from several different companies. But I have to rate the Larsen 5/8 wave at the top of the heap. It performs, it lasts for ever, and it's trouble free. There is an O ring in the base to seal it from even the harshest conditions, including the salt air, (I live on the Gulf coast of South Florida). It's truly commercial grade and just does not quit. What more can you ask?

EXCELLENT !!!  Time owned: more than 12 months
Have had my Larsen 150 for about 12 years now, got it when i first got my license.

it has performed flawlessly til this day, mine is mounted on the Larsen magnet base and the magnet base has a few cracks from the weather and such,, but non the less,,I cannot find any faults in this antenna, I am even amazed at some of the distant repeaters that i have worked with this antenna.

i recommend this antenna to all that is looking for an excellent antenna that wont break your billfold,,get it,,use it,,and enjoy it, you wont be dissapointed

Great Antenna !  Time owned: 0 to 3 months
I installed one of these on the top rear fender of my buddies car which really isn't the ideal spot but it was the most practical in this installation. Due to the the way the fender slopes out this caused the antenna to be slanted. We then tuned the antenna to 146Mhz (snipped a little over a half an inch) and then bent the antenna whip at the base until in was straight. Let me tell you that this was not easy. We then double checked the SWR. The bend had little effect. It is very flexable so it can take some abuse. I'm going to purchase one of these after seeing the performance of this antenna. Below are the results of what I consider a very flat SWR bandwidth measured by an MFJ-259 antenna analyzer.

144 - 1.3
145 - 1.2
146 - 1.1
147 - 1.2
148 - 1.3
