From S.M.I. to M 3.5: Our Story with Antennas

A Trade That Comes From Far Back

I'm Antonio Massimo Castronuovo, and before we were called M 3.5 this business was called S.M.I. Impianti Elettrici, here in Senise. The name has changed, but the trade is the same: I learned to work on antennas and systems watching my father work in the field, and I later deepened it all with specific technical studies. M 3.5 didn't come from nowhere — it continues a family tradition, updated with modern tools and skills.

This video shows a concrete example of our field work installing TV and satellite reception systems — the same approach that today, with professional measurement tools, lets us choose the right antenna instead of always installing a bigger one out of habit.

If you want to better understand how we choose the right antenna for your home, we've written a dedicated guide.
