    Thanks, I've been thinking about an Outback or Forester, so this is helpful to see.

      Thank you. Good luck.

    Can you just run a copper ground strap from your car frame or something grounded to the base of the antenna where it screws into the into the mount?

    You can trim the tab from the diamond and would fit like the comet.

      Maybe I’ll try doing that. I really like the diamond mount. I don’t have to do anything to it other than making sure the grommet screws touch the metal of the hatchback. Sure I might not be able to get 40 m, 20 m works out OK

    Thanks for video, question have you had any problems with any of the subaru electronics or features like hands free lift gate, backup or cross traffic sensors or anything else ?

      Well, using the radio? Or just in general?

    Hey thanks a ton for making this video - really appreciate it.
    I'm not sure though, about the shunt and the two cables/wires that have the holes that connect the coax ground to the mount/vehicle ground -- how did you make that, or where did you get it? Is that something we can get that's generic, or how would I mimic what you did? Cheers, Rich K5OBJ

      The cable with the two holes, that you can buy separately at a ham radio store, it is already made for you. As for the shunt to be more specific it is a shunt matching network: This involves the use of a network of inductors and capacitors to create a parallel or shunt circuit at the feed point of the antenna. This network can be adjusted to change the effective electrical length of the antenna, which in turn changes its resonant frequency and impedance characteristics - meaning that the antenna will resonate better for the antenna is short. My situation is unique for the hatch back of my Outback, good to deep into the bumper, and thus I had to take apart a comet mount and scrape the paint so I can get an electrical connection to the car. Many use a braided cable to connect the comet mount to the car. When I had my other car, I used a Diamond K400 Mount - bet mount you can get - but that didn't work on my new car. I made a video on the K400 - ruclips.net/video/VlSo8eGrLlE/видео.html, and ruclips.net/video/xfmh10t9mGs/видео.html

      @@frankwc0o very good, thank you so much. I will look into the shunt details and see what I can learn / figure out, to make one also. I'll check out those videos too - thank you so much Frank!! Very very helpful (I'm in the middle of setting something up on a vehicle also, so this has been clutch)

      @@rgbking488 Super. FYI, that shunt is used primarily for my screwdriver antenna, and doesn't have to be used for the Diamond HF20CL. Good luck.
