Installed
@RB3offroad 360 degree antenna mount. I duno if they made it this way on purpose, or if it was a happy accident, but its like 95% perfect for what I wanted to do.
With the Honda OEM roof installed, pic from the underside of the rear ROPS bar, up is towards the rear:
Measure once, drink a beer, then half-ass it with the dremel:
Mounted Signal Stalk antenna and cabling:
It's angled a bit to the front (a bit more then normal because it's hitting the garage door), I'd rather the mount had an angled piece so that it would be straight, or bent a bit to the rear, but the Signal Stalk is super bendy, so not worried about branches etc. To get the internals flat against the backside of the roof, it ends up angled like this. Hence the -5% from being perfect. All in all, more than worth the cost for the antenna mount, turned out much better then the half-assed plans I had originally been trying to do.
