King Aircraft SNC501-1213-538-063 Blanking Plate Antenna Upper Fuselage KA350ER

This item was purchased from an aviation surplus sale. I do not know the history of it. It is in good cosmetic condition. It is tagged, "Acft. Model: KA350ER, reason for removal: Antenna Installation". It measures about 11" x 4 1/4" overall. I am not able to test it. It only comes with what is shown in the pictures.
