Back in my DJI Phantom days, I remember conductive cloth tape being all the rage in shielding the GPS from electrical interference.



Do you think there's any validity to this?  Personally, I don't recall seeing that big of an improvement in terms of GPS efficacy ... but this coming from the guy who still uses TPU motor mounts for vibration absorption so go figure lol.

Reason I ask is that my recent HDZero tiny whoop build has the FC smashed up pretty close to the Whoop VTX separated by maybe 2-3mm of space and kapton tape at the bottom of the VTX to prevent shorts (also conformal coated).  But I'm seeing a bit of noise that I don't see on my other HDZ builds.  Now this could be the whoop ultralight VTX not being as good.  But I was thinking of creating a shield of kapton-conductive cloth-kapton and securing that between the VTX and FC.

Just curious if you guys think theres some science to this or just FPV miracle tonic?

I am not sure what material is used in that particular tape but I have adhesive copper tape bought from a guitar shop that has helped with shielding in other electronics projects. You have to ground the shielding for it to be effective.

Diatone made something along this concept: https://www.racedayquads.com/products/di...pack?aff=4

But on a tight enclosed quad build I have not seen solid evidence this helps in any practical way.

Faraday cages and electromagnetic shielding are real and valid things- but, they are not a “one size fits all frequencies” thing, and as Kafie said, it needs to be grounded.

I do love some experimentation, so if you decide to do it, please post your results.

Be careful if you do a google search on EMF, or you’ll very quickly go from actual science to tin foil hat special paint type crap.
