The Group Tour System

Say goodbye to crowd and background noise

We understand the challenges of interacting with groups in busy places. That’s why we’ve built the Group Tour System. It allows you to lead softly spoken yet effective tours without disturbing other people or the day-to-day functioning of the surroundings. It also removes the issues of crowd and background noise, allowing you to focus on what really matters: telling your story.

Don’t have a story yet? You provide the background and artifacts.
We’ll provide the experience.

With over 30 years experience in 52 different countries we know how to create first-in-class experiences you can’t get
by partnering with anyone else. Antenna’s creative content solutions united with state-of-the-art technology will
leave your visitors educated, entertained, and ultimately, brand advocates.
