Yugi-higashi Labo of Ku-chu-sen (wire in the sky=antenna)
This page also serves as the page for JQ1YLK ( Yugi-higashi Residents’ Council Amateur Radio Club, to which the site owner belongs)
In amateur radio, the “antenna” is an important device that acts as the entrance and exit point for radio waves. There are various antenna products available, but without enough plot of land or a tall antenna tower, what can we do?
In Yugi-higashi area of Tama New Town, such people are in the majority. I’ve been racking my brains day and night (?) trying to find a way to put up an antenna that will work as well as possible in a tiny space, such as a balcony or a private garden in an apartment complex.
