$25 · Audioprism 6500 indoor passive FM antenna for fine tuning signal

Use for signals like KNKX, NWPR etc where adjacent signals drown out what you want. Totally passive - no power. Connector was added so you could feed in from another antenna if wanted. Specs :1/4 -wave, capacitively loaded horizontal loop antenna with ground plane; unity gain (OdBi); 360° pickup when horizontal, directional caridiod when vertical; tuneable from 88-108MHz; female F-connector input and output. Located in Saanich.
