The Nyrius didn't work out, but the Mars 300 from Holyland is what I need for wireless HDMI.
I look at the Hollyland Mars 300 HDMI wireless video transmitter kit which transmits up to 300 feet and runs $499 USD at the time of this review.
It's got all the features of Wireless HDMI systems at 3 times the price.
From the other reviews, 300 feet line of sight is an understatement, as I got that inside my studio and house through lots of walls and interference.
For my purposes, I needed something reliable, well built, and would be able to move for my upcoming live streams, and this unit does not disappoint.
If you need this capability, I do recommend this unit.
p.s. I don't mean to bang on the Nyrius, it's not a bad unit as long as you stay close and aren't moving around a lot.
