Note:
Each antenna performs as good as its installation permits it to. Any active antenna is not working good inside a house! It should be mounted OUTSIDE and as high as possible. Place this MiniWhip antenna PCB inside suitable enclosure of your choice and mount outside the house. Probably for the enclosure you can use a piece of the PVC tube which available in various diameters in a local store. Do not use metal enclosure! It won’t work there!

For Max. Sensitivity:
– This antenna should be positioned as high and free from metal conductors as possible.
– The ground plane of the PCB must NOT be lower than the top of the mast.
(the connection to and the antenna surface itself must be ABOVE the top of the mast).

For Best Signal-to-noise Ratio:
– Install the Miniwhip onto a well grounded mast.
– Connect “GND” of the Miniwhip PCB to that mast.
– Place HI-Ui ferrite cores (Ui between 5000 and 10.000) on the beginning and end of all cables to block cable noise currents.
