Seem to have similar/worse performance with LNA

No, it cannot! @azisi and I were digging into an SPF5189Z-based LNA and found that it cannot take 5V DC from the RF_OUT port. After removing the C4 component, I was able to feed it ~4.5V via the RF_OUT port using the built-in Bias Tee of the RTL SDR.

Well that would certainly be the problem then. Looking online, not sure how I’ve missed that before. Will either pull out components or just power it externally.
Thanks for the response.
