Larsen NMO150-450-800 Tri-Band Nmo Antenna

After over a year of use, it works great on all frequencies designated. Specially on digital mode.

This antenna outperforms similar models that I have tried over the past few years. Does great on all bands as described in the specs. I have installed on a trunk lip NMO mount.

The reason I decided to buy this antenna, was due to there not being many out there to be honest, and this one actually had decent reviews. I had purchased and installed the Tram NMO kit with antenna (also rated around 150-800), antenna trunk mount, and BNC-NMO cable for my scanner. It worked well, and pulled signal from what seemed like at least 20 miles according to listening to audio key words, but I also mounted it on the front fender of the truck and did notice it cut out fairly often. I'm not fond of magnet mounts after I've had a few knocked off or roof mounts with holes in my roof, so hood/fender mount was good option. Now, I know people say antennas should really be above the cab...and in a way I agree, so I figured I'd try to find one slightly longer (lol). I removed the tram antenna from it's mount and tested this once it came in. For the record.....it's shorter than my Tram..... But the following result made me stick with it.....The equipment I'm using gives me signal strength for NOAA channels and uses the scanner antenna for those channels. Guess what? The Tram brought in the closest one at the current vehicle parking, and that's about it. It did bring more during driving, but bare with me on this controlled comparison.I installed the Larsen, without making no other changes with ANYTHING.Right off, I had strong signal on 2 weather channels, mid strength on two others, with a total of 4 channels of 7 coming in. Wow!Now, further testing will need to be done with all other frequencies (Fire, EMS, Police, and DOT) But so far, really, to bring in weather in itself (160mhz) much stronger than the longer Tram, I'm optimistic.

I use this for a mobile antenna on the GMRS frequencies and it works great. Paired with my Woxan radio the swr is about 1.6 I can hit the repeater in our area 30 miles away.

Signals on UHF and 700 picked up about 10db using this antenna versus the little Binfu mag mount it replaced. I'm just using it as a scanner/backup antenna so I didn't transmit through it yet.

I’ve had this for about a month now and it seems to be working fine. I did have to run some grounding straps from my truck cab to the inside of the door to ground the door and now it works even better.

Good match for my Larsen nmo setup

Mounted on a Thru Roof NMO mount, very poor performance on 850Mhz compared to a 20 year old Antenna Specialists 3.5db Gain magnet mount. At least 10 to 15 db less signal than the other.
