Will attaching coil shield with silicone diminish performance

[cruzlite]

Will the electrical insulating properties of silicone effect the magnetic output/input of the coil?

coils do not put out "magnetic fields"

its about frequency output

try again

OK...Will silicone affect the RF input/output...?

actually no

no but odds are dirt will still find it's way in & you won't know till
your machine acts up & you send it in & they tell you that is what did it.

Dirt is like ants, & Flys, no matter what you
do it will get in.

I use Silicone type products on all my coils
where the wire enters the coil though,
as double water protection.
Which I also believe is not 100% reliable.

Yes, detector coils produce a magnetic field (alternating).

No, silicone will not affect the field.

Per Jeff's reply, I would only silicone the cover to a solid disc or donut-type coil, not a spider or spoked coil. There are two reasons. One is that you are unlikely to get a 100% seal on a spoked coil cover, meaning that crap can get in and degrade performance. Two is that a siliconed spoked cover will be heck to get back off, and double-heck to clean off the old silicone.

Thanks all !

I have siliconed all my coil covers for the past 3 years and I don't think it has affected the performance at all. If you do, remember to use the silicone type that is clear when dry. Saw a guy detecting and he had used (I think) that blue stuff that mechanics use and it looked really rookie.
