Nice. What is the total height to the top of the antenna? I've got a 12' 6" Class A so I'm looking at the 144/440 COMPACtenna because it's only about 7". I'm a bit concerned about bridge-whacking. And I'm sure my wife will not like my "But it's got a spring!" excuse.
I'll probably U-bolt a piece of angle aluminum to the top of the ladder and mount the antenna to it. The issue is where to put the radio. While your location would work, it only works when I'm driving and not when my wife is driving. I was thinking of a Lido Mount but bolt it under the center doghouse hold-down bolt.
