Active Antennas
Hi, would anybody know (or like to know?) the "secrets" hiding in the pvc
tube antennas like Dressler ARA-500, 900, 1500, 2000 LF-Engineering H800, etc. What kind of element is used as antenna, also the config of the preamp. and the semis used? Their overall efficiency? I know my questions are many fold but still I'd like to know. Thanks to All. Just Curious. |
