Imagine covering all HF bands, ALL OF THEM, 80 through 10 meters, with only one mobile antenna! These adjustable mobile antennas use a simple 12-volt system to change the electrical and physical length of the antenna while you sit inside the car. They come with a cigarette-lighter plug to supply power to the screwdriver system and a small switch panel to provide control. Simply press a button and let the 'screwdriver' mechanism do the work! There is no multitude of changeable coils to mess with and no hardware or tool headaches. You can remotely move from band to band and be sure of a low SWR in the process. As with many HF mobile antennas, Diamond Antenna Mobile Screwdriver Antennas are over 73 inches tall when fully extended and weigh over two pounds. Please take this into consideration when choosing a mobile antenna mount. We certainly wouldn't want your shiny new antenna bouncing down the highway because the antenna mount was too weak! Diamond Antenna provides their screwdriver antennas in either a UHF or 3/8-24 stud mounting. Whichever mounting scheme you choose, you may be certain that Diamond Antenna Mobile Screwdriver Antennas will allow you to change bands easily - without fetching another screwdriver from your toolbox!

work great on my FT857D though its using a separate awitch to move the coil up and down. only issue i notice is it has a slight high swr on 21mhz but no problem. so far its well made and sturdy when mounted on k400 mounts.
