OPEK AM-204-7-SM - Heavy Duty Trunk Lid Hatch Back Antenna Mount
This heavy duty mount fits most all trunk lid and hatch back mounting configurations. It's two-axis adjustment provides flexibility in mounting locations. It is recommended for large UHF / UHF and medium size HF antennas.
Installation note: Included is a small strip of metal that goes between the set screws and your painted surface to prevent unnecessary damage to you vehicle's paint. With that said, some antennas perform better when the set screws pierce the vehicle's metal achieving a better ground. Other antennas do not require this grounding method.
