さやまサークル「アマチュア無線430 八木アンテナで垂直と水平では受信感度に違いがあるかやってみた!~近距離編~」
This video is an experiment using a Yagi antenna on amateur radio 430MHz to see if there is a difference in reception sensitivity between horizontal and vertical orientations. Since this is a local experiment, the effect may not be significant, but I did it as an experiment, so please take a look if you're interested. Filming equipment: DJI Osmo Action 3 SONY HDR-CX470 Video editing: PowerDirector 21 Ultra BGM is from this website: https://dova-s.jp/
