【怪しげな6mのアンテナ】 abstract I got a whip antenna for the 6m band at a junk market.　However, the resonant frequency of this antenna seems to be much lower than the desired frequency.　I first measured the initial value before cutting.　Then I cut about 2 inches and observed the change.　After the fourth fine-tuning, I had a usable antenna.
