[HCARC] Vertical Antenna Data

[Kerry Sandstrom]

Gary,

I've been able to get antenna data on AM broadcast stations from the FCC web site.  The last time I visited, it was http://www.fcc.gov and once I got there i went to the "audio Division" and there was a place for AM query.  The site did provide antenna patterns for the AM stations and provided data on the feed scheme used to generate those patterns.

One place I've found info on VLF through MF ground systems is "Antenna Engineering Handbook" edited by Jasik, Henry, 1961.  Chapter 19 shows a couple of the VLF ground systems including an AF VLF antenna at Marion, Mass built by RCA Communications.  Chapter 20 has a typical ground system for a two element directional antenna.  

The FCC site is easy to find, the old Jasik book is a challenge.  I'm sure there are others.
