Here's what an Ambient BPL tap looks like. This one's on Dalmeny Rd at the home of a Con Ed employee (who has a company car) as documented in Ambient's reply comments to FCC Notice of Inquiry ET docket 03-104 of April, 2003. The yellow thing is the tap off the medium voltage primary. The white cabinet holds the electronics. QRM on 20 meters is S9+20.

The NOI comments also mention a traffic cam. This is probably it as the QRM on 20 meters was S9+20 along this stretch. It's located at the triangle intersection of Pleasantville Road and Chappaqua Road just West of the Route 9A traffic light.
