K400S K-400S Diamond Original K400S Heavy Duty Hatchback/Trunk Mobile Mount - K400 Base with UHF Mount - 13.5 Feet of RG316 - PL259

Works great with my Diamond quad band antenna zero complaints nicest mount I have used

Bought this for my Focus station wagon and it bolted on perfectly to the side of the rear hatch. In that location the length of cable gets a little tight, but Im sure with some extra effort I could get more distance out of it. It was due to the design of the car that it had to be mounted in this location, otherwise I would recommend someplace closer to the center of the roof, say, if you have a roof rack with cross members. I highly recommend going back the first few trips and checking that nothing has come loose due to road/wind vibration. It has a female SMA connector on the radio end, so you may need an appropriate adapter.

Easy install. Holding up well.

Excellent mount.

Good quality

I bought this on the recommendation of another ham operator. He’s had his for 2 years and many miles of use. Easy to install and very solid.

Expensive, but it works so great!

This was recommended by Amazon to go with the diamond quadband antenna. Ordered them together, received them quickly. However this does not fit the diamond antenna that it was recommended for. 2 completely different mounting types for what this fits and what the diamond 8900 quadband requires

This worked well on my Jeep Gladiator with the coax being thin and easy to get inside the cab! Mounted on the hood.

The mount is mounted on the trunk of my Mazda 6. It is secure and solid. it easily holds either my Diamond 70cm/2m or MFJ 1456 antennas with ease. Highway speeds are no problem. Both the seller and product are 5 star, and I highly recommend them both.
