Followed a link to "ainfoinc" dotcom tonight and looked at some of the antenna products they sell. It's direct from china and apparently they will sell individual items, but prices weren't listed. If anybody is interested in it, look down the left column to the Log Periodic section, and Discones to see the specs and pictures. They show what they call a dual-polarization LP antenna, this is new to me. Might be worth an email , which they say they will answer in 48hrs or less. The discone antennas looked sturdy too. The "test reports" listed out to the right side of each antenna usually show photos and the technical information.
