Diamond K400S-NMO Lip Mount, 2-axis Adjustable Antenna Vehicle Mount

Very High Quality . . .

Mount is too big for most compact hatchbacks. Best used for HF antennas. Comet makes a better mount for VHF/UHF on compact hatches.

The mount may work great (still waiting for my diamond antenna) and did mount well to my Jeep hood; however, I had to leave two stars because I didn’t get what I ordered. The adapter that was supposed to be included (and would have been if I had just bought the mount from HRO) wasn’t in the package. I ended up being stuck ordering another adapter and hoping it would get to me on same day shipping.

Very happy with this product.

I installed this on the hood of my Wrangler with no issues. The included cable is good quality, and thin enough to snake through the firewall with ease. I paired it with a Midland antenna and GMRS radio, and it actually improved my reception. Could be the location, could be the quality of this product. Who knows, but I’ll take it.

This is obviously a very high-quality mount. It fit the trunk lip of my 2015 Toyota Camry just fine. I have another trunk lip antenna mount that set me back about $20 and it works OK but there is an obvious difference between the two mounts in quality. You can probably get by with a cheaper unit but if you want a top-notch high-quality mount that will last a lifetime this is your baby.

The unit came in the plastic bag missing one of the allen mounting screws, but that was OK, as three is plenty to hold the thing secure to my hatchback lip. It has both X and Y axis adjustments to make sure the antenna is vertical, no matter what angle the base is at. Im very happy with this unit.

This mount works great on the hatch of our Town & Country. It’s easy to access vs a roof / roof rack mount!

I have an aging, yet classic Dodge Ram 1500 Larime that will be going to our son later this year. As such, I did not want to mark, ding or drill the truck in any way to keep it in great shape. So no drilling, no heavy mag mounts, etc. Nothing permanent or destructive. This mount was the perfect solution and is mounted drivers side to the lip of the hood. Very similar to the Hood Mounts you have seen for trucks, but in my mind much safer that having a piece of metal protruding from the vehicle. This mount is very flexible to help get you as square and as vertical as one can. My only complaint is that the hex screw holding the antenna mount to the main housing does not tighten enough. I have a wobble in the antenna. To date, it does not hinder RX/TX performance, but seems like it should be a lot more sturdy when taking turns, etc. Left hand turns can make the antenna come about 30 degrees off vertical, but always seems to right itself. The same Comet mount seems like it would be much more snug of a fit. But since the Diamond was NMO and simply works...it stays! The thin feed line disappears into the hood gap and through into the cab by hugging and snuggling against driver side door insulation, etc. Not only does it hide itself away, but it has great performance as well. I am used to spending extra money for LMR, but this little cable is awesome! Using Comet 2X4SRNMO VHF/UHF and FTM-300DR to complete the rig.

I was hesitant on drilling a hole in the roof of my Ford Explorer. After much research, I decided that this lip mount, in addition to a Comet antenna would fit the bill. I’m very happy with the build of this mount. It’s very sturdy and the 2 axis adjustments makes fine tuning the angle a breeze to adjust. My only gripe with this mount however is that the 13 foot cable is just about 3 ft short if you need to mount your base station on the opposite side of the vehicle. Other than that, buy this over the cheaper Chinese brand mounts that you find on the big auction sites.
