<p>I normally fly with my VTX on 200mw but sometimes I need it to be more powerful. Whenever I turn it to a higher power setting, though, the video becomes worse.

Where are you when this happens? Indoors, outside, proximity to buildings?

Outside, not really near any buildings.

Huh, that's odd. What's your VTX/goggle setup and antennae?

I have the Skyzone 02X goggles with two pagoda antennae. The VTX is the FORCE VT5804 V2. The antenna on the VTX is the iFlight doom Antenna.

Do the polarizations of your mushroom antennae match? RHCP vs. LHCP.

Yes, the VTX has RHCP and both of the antennae on the goggles are RHCP.
