A microwave AV radio transmission system for reduction in cabled transmission, upgraded signal quality and quantity, lowered production cost, and neater appearance includes a transmitter and a receiver. The bracket has a windshield-facing side and a cabin-facing side. In some embodiments, the hidden dialog is a pop-up notification. The inserts can be constructed of brass or aluminum bronze which is softer than the blade being stabilized thereby to avoid undue blade damage but which are hard enough to provide good wearability and heat dissipation as against periodic blade impacts.
