Graphical analysis: Handmade peeling antenna (Part 2)

　　Step 10: Done!

　　If conditions permit, you can use a standing wave ratio meter to measure the resonance frequency and trim the core length appropriately, which can be adjusted to 1:1.5. If conditions permit, after the production is completed, calculate the final length according to the formula provided above (multiply the shortening parameter by 96%) and trim it.

　　Those who have never used it before can use it as an entry-level training, but don't expect it to have a high gain. In many cases, it will be better than the rubber antenna and telescopic antenna used in handheld devices! But it cannot be compared with the high-gain Yagi, J-type, etc. When you go outdoors, hang it on a tree or other high place, you will find that it has better performance than your original ordinary rubber or telescopic antenna! And because it is a soft wire, it will be very convenient to put away.

　　Another friend asked, since it is soft, how to use it? It is very simple, just use a wooden stick or non-conductive material such as PVC tube (do not use conductors such as iron, aluminum, stainless steel tubes, etc.) to support it.
