Best way to screenmirror pixel 3 without wifi

[Android Central Question]

So I bought a fish house and am going to buy a TV. And would like to mirrror sling TV to the TV so I can watch hockey and football games in the fish house. What tv or device can achieve this? Thanks.

AFAIK the Pixel can only do Chromecast-compatible wireless mirroring, and that only works with a router in the middle (no WiFi-Direct connection is supported).

Another way to do it is to get an USB-C hub with HDMI output and plug the phone directly to the TV (not wireless, and you have to make sure the dongle is compatible with the phone)
