Note that the simulation and measurement results are examples and may vary depending on the specific design and implementation of the J-pole antenna.
Once tuned, solder the coax connections permanently. Apply silicone sealant or self-fusing rubber tape to the feed point connections to prevent water ingress and oxidation. j-pole antenna design pdf
: The element diameter can be chosen based on practical considerations, such as the availability of materials and the desired antenna performance. Note that the simulation and measurement results are
