Mirror Mount for CB Antennas

The RoadPro RP-319 is a thin double-groove bracket designed to attach a CB antenna to a vehicle mirror. It suits drivers who need a semi-permanent mounting point without drilling body panels. The anodised finish and stainless-steel hardware resist corrosion during daily road use.

Thermals Noise and Power Draw

This passive accessory generates no heat, produces no noise and draws no electrical power. The stainless-steel bracket and anodised aluminium body remain at ambient temperature in all weather conditions. Installation requires only hand tools and adds negligible mass to the mirror assembly.

Sustained Load Behaviour

Under continuous vibration from highway driving the bracket maintains its clamping force without loosening. The SO-239 connector stays secure through repeated antenna removal and reattachment. The 3/8-24 stud threads resist stripping during seasonal adjustments.

Questions about this item

How do I install the RP-319 mirror mount and which step is often missed?

Clamp the stainless-steel bracket onto the mirror arm, thread the 3/8-24 stud into the mount, then tighten the SO-239 connector onto the stud — the step many skip is securing the set-screws on both grooves so the bracket cannot rotate.

What maintenance or replacement will the RP-319 need over time?

The anodized finish resists corrosion, but the 3/8-24 stud threads and SO-239 centre pin should be inspected annually; replace the stud if threads gall or the connector if the pin loosens.

What is the first limit that appears during sustained highway use?

Wind-induced vibration at the double-groove clamp interface is the first limit; it can loosen the bracket bolts and degrade the SO-239 connection before any material fatigue occurs.
