Topband: Receiving Loops (score: 1): Author: Thomas.Damboldt@t-online.de (Thomas Damboldt) (by way of Bill Tippett<btippett@alum.mit.edu>); Date: Mon, 29 Dec 2003 11:05:46 -0500; Hi all, in high local noise, would it be advantageous to put a small receiving loop on top of a tower? In my simple mind this would at least remove the antenna some 15 m away from the sources. Is tha; /archives//html/Topband/2003-12/msg00263.html (7,482 bytes)
