Thanks for the response. The iCopy-XS contains a housed proxmark with built in antennas. Im not sure the antenna is actually visible. If you want to take a look at the product its here: ICopy-XS | ICopyX
But yes im aware that it needs to be perpendicular. Once i found that out i started getting much more consistent reads from the NFC side as well. But im literally getting nothing from the LF side with either the proxmark or flipper zero, regardless of any orientation i try.
