Best stuff to shield a VTX?

I have a TBS Gemini and there is no room to move the Spektrum Sat away from the VTX that I installed. It's a much higher output unit than stock and I feel that it's putting out a lot more RF so my 2.4 link range is being weakened.

What should I wrap the VTX in? Cooper or Aluminum?

Thanks

Aluminium or copper but you need to connect your shield to the ground. Also do not leave space to allow the metal to heatsink

Shielding the case of the video-Tx is not likely to make any difference. While the case might have a minimal amount of RF-noise, it's a lot more likely to be radiated harmonics directly from the antenna. It could also be the 2.4Ghz receiver, that's not able to handle the power-full signal nearby.

If you really wanna continue with that setup, I would try high/low pass filter on video-tx or 2.4Ghz receiver. You didn't write video-frequency, but I guess you are using 1.2Ghz?
