Installing the Bird repellent fixture
Sea birds such as seagulls may be the cause of poor reception of the GPS signal when perched on
top of the GPS antenna unit. The use of bird repellent fixtures is recommended to alleviate this
problem. To fit this device, use the following procedure:
(1) Secure two bird repellent fixtures (D73MB23040) on the arm of GPS antenna GA-11 as shown.
(2) Firmly fasten each device using a weather-resistive tie through the GA-11 fixing hole. We
recommend that the devices are co-fastened with the waterproofed antenna cable. If these are
attached after the antenna cable is fitted, the device may be floated causing loosed fixing.
NOTE: The weather-resistive ties are not supplied as standard.
