It is known PA0NHC newest design. I have redesigned its PCB and built it on SMD components but the circuit diagram itself remained the same as it had been in his original model described on his web page in open source.
This new version of PA0NHC MiniWhip Antenna has these features New version, using modern BF998 and BCX54 semi conductors.

PCB Size: Length (mm): 155 x 27
Feed line: 50 – 100 ohm coaxial cable up to 100 meter long
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.
