![]() I've been told that braid makes a great deal of difference to common mode noise pickup, and that while a thin foil and loose braid is fine at UHF it's not to be expected to do the same for HF. Even if you accept the principle that foil is worse than braid for common mode signals, where do you think these signals are coming from? Unless the cables route close to the source of the interference then your antenna is going to pick it up much more than any difference in shielding. http://www.abccables.com/info-rg59-vs-rg6.html is one of the more descriptive texts I read. No RG6 that I have found fits the description given there for HF. RG59 does though, as does BT2002. I think I'll be going with that BT2002 anyway, never mind the expense. The waste of time trying to avoid it is alone beginning to look more expensive than the price difference. I must admit I do not understand the theory that foil is worse than braid at lower frequencies, foil gives 100% coverage and is usually in addition to braid. Even if it the thickness of the foil that is in question, I don't see how, according to the article that you linked to, it " don't(sic) have the proper type of shielding ". There may be an issue with terminating foil shields well but that is a different matter. |
