Guys,
I apologize for the way I came off in my last post. I am definitely not one to claim to have all of the answers.
I have consulted our in-house RF Engineer regarding this topic. He said that many old school cable guys were taught that rf signal travels on the center conductor, which in fact it does. However, many satellite techs, which I am, are taught that it travels on the outside of the center conductor, which it also does.
The difference here is the frequency ranges that the two different systems use.
The lower frequencies travel closer to the center of the conductor, but the higher frequencies travel on the outside of the center conductor (skin effect).
He says that many satellite techs are taught by people (SBCA and DOW Electronics) that say the satellite signal (RF) travels through the dielectric foam because it is on the outside of the center conductor.
He says that argument can be made, but at the same time, none of the three components by themselves will conduct current (signal), and foam cannot transmit rf signal.
If I have offended anyone I am truly sorry.
