I'm also a new guy and came here looking for recommendations on an antenna setup. My truck has a flat bed with headache rack and I do not have the same clearance requirements that the OP has. So my question is, given two choices, would it be better to put an L bracket on the hood or put the L bracket on my headache rack. Advantage of headache rack seems to be higher elevation and potentially less interference, but slightly spaced away from hood and perhaps reducing ground plane? Advantage of the hood mount option would be a better ground plane, but I'm not sure that will actually be the case. I will eventually put in a proper roof mount, but was looking for something quick to be up and running and was hoping someone would have some advice on application.
