A:Answer I don't know that they have to be smart, they do have to be HD, I don't know what a romulo is but this device is fantastic with great picture quality, first had it sitting in my living room got a really good signal, on my roof fantastic signal. just run coax from unit to tv and you have local channels. I have two tvs on same antennae. Both of my tv's are new. I had used a hd antenae on my rv, airstream and at a house for the past 10 years and they all work great so any tv you have less than 10 years old should work! You won't get cable channels. Just local networks, we get 33 channels
