Active Receiving HF Antenna Navtex

Description

MiniWhip Active Antenna
To note please:
My original Antennas you can buy
ONLY
here in this sale or in my web store!
I am not supplying them to other sellers.
T
here are a lot of fake Chinese Antennas available on Ebay or in other online auctions. Those Chinese monkeys even printed my Web Store URL on their fake Antennas!
My antennas have the high quality metal connector there. All my products are
personally made by me in Ukraine and a
ll my packages go from Ukraine.
So if you bought the fake Antenna somewhere else do not ask me why it is not or bad working. I will do not answer on such questions. Ask it the seller you bought it from
!

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 wont 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.
