There are standards - generally requiring the antenna to be reasonably well behaved +/- 10 KHz or more - is order to support both AM stereo (if used) and "HD (digital) radio" > Small, local, transmitters would have "small" antennas with > much lower bandwidth than a big transmitter and therefore some > additional self-limiting of transmitted bandwidth. Not necessarily. Antenna height is driven to a large degree by the requirement to maintain specified field strength and minimize high angle radiation that causes skywave interference within the coverage area. > Is the transmitted bandwidth part of the measurements > required for broadcast transmitters? Not specifically for audio response measurements. 73, ...
