The magnitude of the RC without its angle is just another worthless number. It can't be used for anything except to calculate a fictional SWR. Actually, it is pretty useful for a Z0-matched system since there is one and only one unique solution at the Z0-match point. In a Z0-matched system, all forward and reflected voltages and currents are at the reference zero degrees or at 180 degrees so all the phase angles are known without measuring them. The physical reflection coefficient is a function of Z01 and Z02 at a Z0-match point. The sign of the reflection coefficient corresponds to either zero degrees or 180 degrees and depends on whether (Z01 Z02) or (Z01 Z02). Since the great majority of amateur radio systems are close to a Z0-match, this becomes a useful analysis tool for the most common cases. -- 73, Cecil http://www.qsl.net/w5dxp ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 100,000 Newsgroups ---= East/West-Coast Server Farms - Total Privacy via Encryption =--- |
