SUMMARY

The parabolic dishes observed on lampposts are primarily used for microwave and UHF communications. These dishes, approximately 18 inches in height with bars spaced 2-3 inches apart, are strategically positioned to optimize signal transmission, particularly in areas with significant distance to the next landmass, such as over Lake Ontario. Their orientation, specifically pointing Southeast, suggests a targeted communication purpose, likely for data transmission or surveillance applications.

PREREQUISITES
  • Understanding of microwave communication principles
  • Familiarity with UHF frequency bands
  • Knowledge of parabolic antenna design
  • Basic concepts of signal propagation over water
NEXT STEPS
  • Research microwave communication technologies and their applications
  • Explore UHF frequency band regulations and usage
  • Study parabolic antenna design and optimization techniques
  • Investigate signal propagation characteristics over large bodies of water
USEFUL FOR

Telecommunications engineers, radio frequency specialists, and anyone interested in the applications of microwave and UHF communication technologies.

I've seen a couple of these dishes high on lampposts over the highway. They're about 18 inches high. Bars are about 2-3 inches apart.


Not common, I've only spotted two so far. Both were pointing SouthEast. The reason I mention this is because one of them was on a shoreside highway and was pointed out over the water (Lake Ontario). The next land is about 30 miles away.

What kind of communications is this used for?
