Has anybody tried this copper tape from amazon for shielding a coil. It can be easily solder on and it says that even the adhesive is conductive which I have proven be wrapping 2 1 inch pieces at each end and soldering them down. As you can see in the pics only getting .3 ohms resistance through it. I hope the adhesive is conductive because I ripped the tape in half once while I was wrapping it around the coil but right now it seems to work fine. Any thoughts?

Well, if you are getting continuity between both ends, it means that it's having connection all the way around. And that's what you want. And you left the gap. About the resistance, I can't say. -

Ok dbanner i will try to do that in the future, sorry don’t know what I’m doingComment

Ok Tibuck19 soon as I get this working I will let you know how it works but keep in mind i am using this on a old BFO project that am playing with at this time. It may not be the same for other MD. But its a starting point.Comment

I must say I was pretty amazed how this stuff works, easy to solder to and the fact that the adhesive is conductive so if it breaks you can carry on and still have a complete circuit . How long will the adhesive keep conductivnees is the question. And it says its resistant to corrosion but for how long. Time will tell. Let me know how it works for you as well.Comment

Thanks RobN. Personally I feel both this and the pot questions deserve their own threads, and I have learned from the replies. I have some aluminium shielding tape, and was wondering about conductivity. Now I will presume the adhesive on this is also conductive.
Many instructions neglect to mention these type of essential points, even ones specifically directed at amateurs.Comment

good for reading my friend and seeking new knowledge around. begin from a book, not from cooper tape.

I take that back. You are right to open new threads. It is good.Originally posted by dbanner View PostYou need not open new thread for every comment/ question. You can leave it all under one thread so that future person who might want to make this device could follow easy. Just a suggestion.Comment

OK, I have the book and read the book, don’t know what any of this has to do with the book. I don’t recall anything in there about copper tape with conductive adhesive but I my be wrong. Just trying to be helpful to anybody that may be interested. Sorry to be a pest and a new comer to this forum. I will try harder next time.
Tibuck19- so for my test have came out more that I expected, compared to aluminum foil. I have ran some simple test with it and it seems to work great although I haven’t actually tested it the field yet. But what I have seen so for compared to using aluminum foil is a major difference. I will let you know more after I do more test at a later date. Please if you try it let me know your findings as well. Thanks, RobComment

The way that tape looks to me is the same you use to solder the dense Smd on mobiles, tablets laptops etc and there it stops the heat. Am I right or this is different copper tape? Also don't you afraid at lower delays it will be detected as target? Think the best way is to build two twin coils one shielded one not and see how it will be. Whether the shielding will or not decrease dramatically the dept. Off cause all I say depends what are you going to search for, so accordingly it may do or not do the job in your particular case. I'm sure though I've read somewhere in the forum that copper tape it is not suitable, only not sure which type exactly.Comment

I use the copper tape all the time, works great. The 1/2" wide tape is easier to wrap around. I cut the tape to about 20" lengths and overlap the ends. Just make sure you burnish down the tape after its applied to make sure you get full contact.
You must make sure you buy the copper tape with "conductive adhesive". Usually will have a green core. There are many copper foil tapes that do not have conductive adhesive with a white core--depends upon the seller.
