I have my Yaesu ATAS installed on my Ford F250 pick up truck, using the diamond K 400 mounting hardware on the hood of my truck. Yaesu recommends a strong bond between this antenna and the chassis of the truck, but I don’t see how to do that. I did use some sandpaper and scrape the paint off underneath the Diamond K - 400 mounting hardware, but I don’t see any way to bond this antenna to the chassis of my truck. I would appreciate your suggestions TIA.
Hi, you don't need to remove the paint from the vehicle to establish a good grounding. I made the counterbalance by clamping an 8mm square cable (the green yellow cable) with a suitable cable lug (here with a pre-insulated diamond grip cable lug) under the diamond K-400 holder and then clamping the other end of the cable inside the trunk at a point behind the trim where there was already a connection for grounding. I then measured the contact resistance to make sure the grounding was good. The ATAS antenna worked perfectly and I always had a low SWR.

We hear your mic on but you can’t talk?
