Reddit mentions of J-Tech Digital HDbitT Series 1X2 Wireless HDMI Extender 200' Dual Antenna Supporting Full HD 1080p with HDMI Loop Output IR Passthrough [JTECH-WEX200]

Wireless HDMI

Do not have, zero idea of how well it works. But it is a place to start. Good luck.

Very cheap option: If you already have a BMDVA then you could use a consumer HDMI home transmitter depending on your room distance.

​

So your signal flow would go: Source->Cheap (maybe monoprice) SDI to HDMI converter -> HDMI Wireless transmitter -> HDMI Wireless Receiver -> HDMI cable from receiver into BMDVA.

To power the receiver in a wireless way you'll need power on the go. This provides 5v with the standard 5.5mm plug. Never put more than the rated amount of voltage into a device, or else white smoke magic will happen.https://www.amazon.com/Generic-Battery-Holder-Connector-Arduino/dp/B00O5AZI12/ref=sr_1_11?keywords=5v+5.5+battery&qid=1549747721&s=gateway&sr=8-11

Laggy option on the cheap: If you have a macbook get a BMD SDI Recorder : https://www.blackmagicdesign.com/products/ultrastudio, shove it into the macbook and OBS, and private stream over platform of your choice (Youtube/Twitch etc) and monitor with the Ipad wirelessy (as long as you have a house wifi network, or your own of course).Windows option: Elgato H60 is a piece of trash but does work.. most of the time. This option total would be around or less than $200. Hope that helps!

/u/Taidaishar - if you're OK with two cameras, you might want to consider a [Blackmagic Web Presenter with a Teranex switch panel for $550] (https://www.amazon.com/dp/B06X3W3HQS//ref=as_li_ss_tl?ie=UTF8&linkCode=ll1&tag=battleforthew-20) instead of the Sling Studio.

You would also need a [$39 Blackmagic HDMI to SDI micro converter] (https://www.amazon.com/dp/B077QQSP5N//ref=as_li_ss_tl?ie=UTF8&linkCode=ll1&tag=battleforthew-20) because the Web Presenter has one HDMI and one SDI input.

[Here] (https://youtu.be/TFzFAZLSu_Y) is how a two-camera setup works with the Web Presenter and the Teranex.

That leaves you enough for a [$450 used Panasonic FZ1000] (https://www.amazon.com/Panasonic-DMC-FZ300K-Megapixel-2-3-inch-Dustproof/dp/B011PKJI2Y/ref=as_li_ss_tl?m=A2L77EE7U53NWQ&s=warehouse-deals&ie=UTF8&qid=1524049831&linkCode=ll1&tag=battleforthew-20), which can give you results like [this] (https://youtu.be/tE3yFeQg6BI) in a broadcast/webcast setting.

When budget permits, you can get [relatively inexpensive J-Tech wireless HDMI transmitter/receivers] (https://www.amazon.com/dp/B071VCK1FG//ref=as_li_ss_tl?ie=UTF8&linkCode=ll1&tag=battleforthew-20) to get rid of the cables.

Hope this is helpful and Godspeed!

The signals coming from the TV station are already wireless. The trick is to capture those wireless signals with an antenna, then a Tuner, so they can be converted to HDMI (what your television needs). Then you have to convert the HDMI to wireless using these expensive gadgets: https://www.amazon.com/J-Tech-Digital-Wireless-Supporting-Transmission/dp/B071VCK1FG/

• Personally I'd rather run a 50 foot coaxial cable from the attic to the TV (which is what I did). It was cheap.
  
  

Properly transmitting the analog signal (what you get over coax) with reasonable quality isn't really possible on the free frequencies. Transmitting the full digital signal that HDMI carries over wifi isn't really possible either (you need 48Gbps or so).

So your options are two, one, for cable, you can capture the raw digital stream transmitted and send that over wifi. the HD Home Run will do that, it's only really good for cable/TV, but it works well, and gets you full quality with minimal cost, but the user interface is going to be a bit different (you need to access it via streaming on the TV, maybe with a firestick or similar). The HDHomeRun won't tune to analog streams if this is cable and it happens to have some, it also adds significant latency and won't do for games.

The second option is get an HDMI wireless converter, they are expensive, add significant lag (and are no good for gaming), and reduces the quality as it must recompress all video.
