It's better to buy a cleaning fluid for lens filter. 

No, it hooks to the TV via the coax cable input on the TV. 

This antenna will not help with your streaming service from buffering. This antenna will only receive over the air broadcast TV stations. 

I don't see why not, remember that the filter goes on the lens, not on the camera. 

This antenna will receive over the air (OTA) HD TV. I cant speak to your tv but I dropped cable 13 months ago. With Amazon prime you will receive a whole bunch of content. With HDTV you need a fair amount of band width to avoid buffering. You will probably also want an over the air digital video recorder (DVR) unless you are willing to put up with adds. I use Tablo. There is a whole bunch of minutia on how to get what you want but my house entertainment went from $250 down to $95 a month . Good Luck it is worth the savings don't pirate anything. Jim
