These beacons used large loops to develop the beam(s), see http://www.navfltsm.addr.com/ndb-nav-history.htm . I seem to remember seeing some pix somewhere on the web but can't seem to find them anymore. A "Google" on pertinent terminology of the era should turn up something. 73 de Mike KB6WFC k .. --- "Ashlock,William" wrote: > Anyone know of any old-time loop > applications for long distance > transmission? __________________________________________________ Do You Yahoo!?
