wireless HDMI suggestion... with a twist

[surfacemount]

Ok

I am working on a project.

I am inserting a hdmi pickoff in a system. This system uses a 2.4 and a 5.8 link.

I want to pipe A/V from this pickoff to a short distance remote video monitor using a wireless dongle.

Because the system is very sensitive to interference in 2.4/5.8, I need this dongle to link on another band. Another channel isn't good enough.

I would also like this to be inexpensive.

Does this exist?

Thanks in advance!
