I have a project described in my "Introduce Yourself" section: https://forum.dronebotworkshop.com/introductions/ps4-esp32-arduino-ide/#post-52540
I have had success getting wifi from an underwater gopro via an RG174 coax cable like in this post:
https://www.paulillsley.com/GoPro_Underwater_Wi-Fi_Cable_Setup/
That works well when the one end is on the gopro (hero4) and the other is on my iphone but what I really want is to run the cable from the gopro to my rc boat and have it relayed to me via wifi so that I am untethered from the boat. The boat works off shore far enough where cable management is impractical.
Is there a way to take the signal that would normally be taped to the back of the iphone (as in the attached link) and wifi it to shore with standard gopro wifi connectivity?
The boat has battery bank so dc power can be supplied. It has an esp32 onboard if that is needed and others available.
Please look at the links and any feedback will be appreciated.
Thanx,
Guyzly

Can the esp32 on board act as a server and read the frames from the gopro then your phone would connect as a client to the esp32 to be served the frames ? If you can get frames from your gopro to the esp32 on board then you can just serve those frames. I don't know if the esp32 has the bandwidth to both take frames in and send them out. But you probably could get by with a few frame a second.

Thanx noweare, I had considered that but thought the band width would be the issue. Slower frame rate and lower res may be ok tho but would slow scanning too. I guess i was hoping for a 20.00 off-the-shelf antenna solution but may try your suggestion if I get the time to figure out how to implement.
