About NDBs
NDBs or Non-Directional Beacons inhabit 190kHz to about 500kHz, the large majority being between 200 - 430kHz
AMRAD LF Active Whip Antenna
You can tune into LF activity with this easy-to-build and erect active antenna
Antenne per il radioascolto
Valutare e provare quei circuiti tanto odiati e tanto amati che si chiamano antenne attive
