This is a very simple shield for SMD in-line filter with SMA connectors; just my two cents worth.


Make sure to use full length threaded connectors (i wonder why this type is not used all the times). I purchased them on Ali at $2.50 for 10pcs. At least one coin should be fully soldered; the other one can be soldered in a couple of points only. I did not do it yet but i will do it soon because leaving them free everyting comes loosen easily.

Total cost of the enclosure: 0.20€ including the two coins. Actually i have spent 5€ for one meter bar but i estimated the cost dividing, according to the pieces that i can make with it.
