In summary, the conversation discusses a potential wireless traffic camera transmitter that is connected to a box by coaxial cables. It is speculated to be part of an outdoor lighting control system and may also have additional functions such as traffic monitoring. The dual antennas are likely for better communication in urban areas. It is suggested to check the city's website for information on any new systems being installed. The conversation also references a similar situation in a stadium parking lot.

TL;DR Summary
They have two small whips with loading coils and a box seeming to be something that may receive, amplify and retransmit something, I see no sensing devices and they are not specifically located in proximity to anything: neighborhoods, offices, intersections etc. Anyone have an idea what they are?

Wireless traffic camera transmitter? Looks like coaxial cables plugged into bottom.
See the camera or sensing device mounted on the light boom connected to the box by coax.

Might be part of an outdoor lighting control system. They could be gateways between RF and the local powerline in order to communicate with some number of light poles in the neighborhood. They could include other functions too, like the traffic monitoring suggested by @Klystron :smile:

The dual antennas would likely be for spatial diversity to help with the typical multipath issues in urban communication.

BTW, if you do a search at the city website, you may be able to see if they have installed some new system or are doing a trial with some new technology (like streetlight control). Which city/county did you see these in?

EDIT/ADD -- For example, see this thread for an example of something similar that I spotted and posted about, and @wirenut was able to identify what it was (a new city system):

There appears to be a cable retrofitted into the light sensor on top of the lamp.

1. What is a Central Coast Receiver/Transmitter/Antenna System?

A Central Coast Receiver/Transmitter/Antenna System, also known as a CCRTA system, is a type of communication system used to transmit and receive signals between two or more locations. It consists of a receiver, which receives incoming signals, a transmitter, which sends out signals, and an antenna, which acts as the interface between the system and the outside environment.

2. How does a CCRTA system work?

A CCRTA system works by converting electrical signals into radio waves, which are then transmitted through the antenna. The antenna then receives incoming signals and converts them back into electrical signals, which are then processed by the receiver. The transmitter and receiver work together to ensure that the signals are sent and received accurately and efficiently.

3. What are the main components of a CCRTA system?

The main components of a CCRTA system include the receiver, transmitter, antenna, power supply, and control unit. The receiver and transmitter are responsible for sending and receiving signals, while the antenna acts as the interface between the system and the outside environment. The power supply provides the necessary energy to operate the system, and the control unit manages the overall functioning of the system.

4. What are the advantages of using a CCRTA system?

There are several advantages to using a CCRTA system. Firstly, it allows for long-distance communication, making it ideal for use in remote areas. Additionally, it is a cost-effective solution for communication as it requires minimal infrastructure. It also provides reliable and secure communication, making it suitable for military and emergency services.

5. How is a CCRTA system different from other communication systems?

A CCRTA system differs from other communication systems in that it uses radio waves to transmit and receive signals, while other systems may use different methods such as cellular or satellite technology. Additionally, a CCRTA system is typically used for long-distance communication, while other systems may be more suitable for shorter distances. CCRTA systems also tend to be more cost-effective and reliable compared to other communication systems.
