Roamio and OTA antenna streaming

I live in Morgan Hill, CA and the number of channels OTA are limited. In Los Gatos there are more channels. I am planning on setting up an antenna in Los Gatos and connect to Roamio. Then I would like to stream from that Roamio to my home in Los Gatos via a Laptop.

Will this work?
What is the picture quality?
How well does it stream?
