tilted antennas | TruckersReport.com Trucking Forum

The radio tech I try to use stated that if you are dealing with a truck with the exhaust stacks directly behind the doors, such as what you might find on a Peterbilt 379, it is best to get the antenna as far away from the stacks as possible. Since, in normal situations, the antennas are mounted to the mirror frames the only way to increase the distance is to tilt them away from the stacks. Sounds logical, but, I donno.

The stacks on my ‘Shaker are at the rear of the cab, and, are short to allow me to access chemical loading racks. I still tilt my aftermarket antenna because I don’t want to get it tangled in a rack, plus, it just plain looks “kewel”.

One other thought comes to mind. If you mount the antenna straight up, then proceed to travel down the interstate at 60+ mph you are effectively tilting it toward the rear due to the air resistance pushing against the mast. If you’re tilted forward, the air flow will push the mast upright to a more straight position.

2xR, doubting any of this matters with a 4 watt radio.
