Connecting external aerials to FM radios without one

[Murphyv310]

""Specifically those with only lengths of wire as aerials""

Wire fitted inside receiver, outside receiver?

Need more info such as make/model/schematic.

Hi.
Yes a diagram would be of help, TBH any I have done are fed from an internal transformer or battery which will be isolated from the mains, the addition of the 10pf caps suitably rated will alleviate any fears of isolation, this though should be handled by the mains TX.
