To note please:
Each antenna performs as good as its installation permits it to.
Any active antenna is not working good inside the 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 will not work
inside
!
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.
- Use high
permeability
ferrite cores (Ui between 5000 and 10.000) on the beginning and end of all cables to block cable noise currents.
