Denny's Antenna Service Antenna advice and sales
Roku best streaming device in my opinion, go with the Premiere or Ultra model for best speed and features
Sling TV The best deal in a streaming service, have used it myself over a year now. Packages start at $20 a month, $25 or $40 for all, with lots of options after that too.
Playstation Vue another streaming service, packages cost a little more but offers more selections. $29.99-$64.99
Titan TV Best online tv channel guide, customizable to what you get and actually watch, also has a nice iPad app too
