Product ReviewsK400S K 400s Original Heavy Duty Hatchback/trunk Mobile Mount K400 Base W Black

Diamond K400S rocks!

This was an easy to use mount for an antenna that was given to me, the coax cable on first review i thought too thin but it makes putting it through a fire wall a breeze. Make sure that the four set screws ground to your vehicle and if all possible place additional ground straps. Protect the coax from pinching or sharp edges, comes complete including an adapter to use on a regular PL-259 connector. I use this with the Diamond 62in SG7900A mobile antenna and a Yaesu FT-70DR, works great on Simplex as well as Repeaters. I mounted this on the left side edge of my Titan's hood and I have driven highway speeds of over 90mph without any problems. I plan on purchasing other Diamond products in the future.Read full review...

Good quality, but may not be suitable for 10m band.

After mounting the antenna it felt solid. That is, after all, the primary purpose of the mount. Using the Diamond CR8900 antenna, I was able to get the following SWR measurements on the 2m 6m and 10m bands. I write them here as pairs of MHz and SWR separated by a comma for each pair: 144, 1.6 - 148, 1.2 -- 50, 2.5 - 54, 1.4 --
28.0, 1.3 -- 29.7, (high). On 10m the SWR of 2.0 was reached at 28.22 MHz and higher frequencies were quickly worse. I followed the instructions to ground two of the set screws into bare metal after grinding off the paint from the inner lip before I ever tried to measure the SWR, but the performance on 10m was just a very small portion of the band. The problem may be entirely due to the antenna and not the mount. The quality of the materials looks good. The design seems to allow for many different configurations and angles so that the antenna could be made vertical while the mount is attached within a wide range of orientations. The instructions could have been more detailed or with more explanations. I have had this mount for only one week. I have had no other mounts, so I cannot compare this to others. Read full review...
