Are they being nice or is their phasor obsolete? Phasors can not be obsolete. They can be badly designed, hi-Q and narrowband, but there is no real change in components (coils and caps and vacuum caps) or design since the first directionals on AM were used at WSUN and WOR in the 20's. The big thing for an Analog AM/MW Radio Station that is going to begin IBOC {Integrated} Analog and Digital Broadcasting : Is will their Single Tower Non-Directional Antenna handle the 30 kHz Bandwidth required of IBOC ? Most single towers are flat enough and don't have a disparate enough reactive component to do HD easily. The problem is with directional systems that were designed for easy tuning and have a high Q. These have to be broadbanded... most larger stations already did that to make analog audio sound better. You seem to have an incorrect understanding. Not surprising. Please set us straight... |
