We were using a 100 Watt transmitter! What do you expect? Of course it
worked well 20 miles out when we had line of sight. Still with a dinky
omni antenna. An SFN of such transmitters in NY would work wonders.
And the bit rate could be, with that SFN, above 18 Mbps and with MPEG4
this is not an issue.
