Thanks for the input guys. I think i'm on the right track then.
One more thing, there are a couple of Baluns visible on the picture. Is there a way that an amateur like myself can analyse these? I've found some that are reasonably similar in size, but I believe that the material also makes up a great part of the specs. I do have some signal generators and oscilloscopes laying around, only no spectrum analyzer or anything. Any input would be helpful.
