This. I used to have a cheaper antenna like a Leaf (not the exact same brand, but close) and after getting a ClearStream 4 I've never looked back. Put that sucker up in my attic, dialed it in and get GREAT reception.

I have this in my attic, and it works quite well for me.

Hey man, hopefully we can help you out. I don't know everything when it comes to cordcutting, but I'm pretty tech savy and have been without cable now for about 7-8 years. I'm hoping some others chime in here too, as I'm not a huge sports fan, so I can't cover everything there. But catch every Packer game free in uncompressed HD with a ~$150 antenna. $150 may strike you as expensive, and it is, but think about what you pay for all the channels you don't watch via cable. It will pay for itself in a month once you completely cut the cord.
For General TV:
The first thing I would encourage you to do, is buy a decent antenna. Don't cancel you cable yet. Everyone's home/surroundings are different and antennas are effected by all kinds of materials in a house/apt. This way as your learning what works and what doesn't, you won't get frustrated and give up completely on cutting the cord if you hit a roadblock. Bascially start small and work your way up would be my general recomendation. This worked for me at least. Now I pay for internet service, Netflix, and Amazon Prime, and couldn't be happier.

Antenna Placement: Generally the higher the better, the bigger the antenna the better, and the clearer the line of sight to the TV Towers the better. ex: Mine is in my attic so the signals travel through my roof, thru some tress across the street..etc.

I'm not familar with the homerunhd, but just checked it out. Looks like you can stream to different devices from this. If your roomates have a smart tv, you may be able to stream directly to them. At the very least I see Android on there, get a $30 Chromecast, plug it into the roomates TV, and with their tablet or phone you should be able to cast it on the TV.

If you havent bought the homerunhd yet you could check out Plex. Run the Plex server sw on your computer, and the plex clients on virtually any device. Stream right thru your network. The homerun may work similar, if so it should work just as well.

Another Option:
If you have an Xbox one, you can get the OTA adapter for it, and play TV right thru it. And Microsoft will be adding DVR support to it at some point.

For the Major Sports fan:
For soccer, you don't need cable. I watch mostly soccer as I'm a pretty big fan, so I can help here a little. A great sub reddit: https://www.reddit.com/r/footballdownload/
Its not live, but I actually prefer watching something after it's aired as I LOATHE commercials.

For NFL, MLB, NBA..etc... I would start by looking what streaming services are out there and compare what devices they are compatible with. This may be your determining factor for the roommates in room devices.

Hopefully someone else can chime in here for ya, as just don't have the experience with the other sports. What NFL, NHL MLB and such I watch, I get my fill via my antenna as I'm not a die hard sports guy....except soccer.

Sorry if I rambled and if you have questions just ask.

thanks i have this one https://www.amazon.com/ClearStream-Indoor-Outdoor-Antenna-Mount/dp/B008PBTPOI/ref=sr_1_74?s=electronics&ie=UTF8&qid=1538678223&sr=1-74&keywords=tv+antenna
in attic but don't get channel five

I actually live in Norwalk as well, by Brian McMahon high school. [I have an older single version of this antenna.](ClearStream 4 Indoor/Outdoor HDTV Antenna with Mount - 70 Mile Range https://www.amazon.com/dp/B008PBTPOI/ref=cm_sw_r_cp_api_IpAOybQVG0ANY) it works ok but because it's a single I can only get either New York or Ct news and because NY has it's a much stronger channel.

[I am about to purchase this antenna] (8 Element Bowtie Indoor/Outdoor HDTV Antenna - 70 Mile Range https://www.amazon.com/dp/B00C4XVOOC/ref=cm_sw_r_cp_api_InAOyb9KCNGKX), my father in law has it and it's fantastic but you have to put it outside. The first one does work inside in most locations.

I'm in East Point. We've had a Clearstream 4 on the roof since in February. It was on sale at BJ's for $49.

The GPB channels (8.2-8.3) occasionally drop depending on the weather. Apparently, this antenna is for UHF, and channel 8 is VHF. But everything else comes in great.

Go with this: https://www.amazon.com/ClearStream-Indoor-Outdoor-Antenna-Mount/dp/B008PBTPOI/

Or CM4228 (though it might be overkill): https://www.amazon.com/Channel-Master-CM-4228HD-High-Antenna/dp/B000FVVKQM/

And I am using the ClearStream 4 Indoor/Outdoor HDTV Antenna with Mount - 70 Mile Range (https://www.amazon.com/ClearStream-Indoor-Outdoor-Antenna-Mount/dp/B008PBTPOI/ref=sr_1_2?ie=UTF8&qid=1467308345&sr=8-2&keywords=70+mile+tv+antenna).

EDIT: I think it is closer to 20- 25 ft above the ground.

Would an powered amplifier help?

Thanks!! :)

This is what you want:

You will probably want a preamplifier, too:

Just mount the antenna in your attic, aim it at San Jose/SanFrancisco (west-southwest of you), and jack it into your existing cable wiring. It's a lot easier than you think. With this antenna, you'll get EVERYTHING. I have this setup, and it's 100% worth the extra cost. The picture is crystal clear, and you'll get dozens of channels.
