RF Feedback in a Mobile

[W3XWT]

I’m about to install my Icom 7000 HF/VHF/UHF xcvr in my compact car. In every other mobile HF installation I’ve done, I’ve been bedeviled with RF feedback problems, some of which were still there when I either wore out the mobile mount or it had suffered catastrophic structural damage. Plus, this time, I’m remote mounting the radio in the luggage compartment and putting the control head on the dash. So, any thoughts from others who’ve been down this path of late? The IC-7000 will be mated into an Outbacker Perth on HF and a Diamond collinear on 2m/70cm, both on magnet mounts atop the passenger compartment. 73
