Re: [WISPA] Transmit Antenna Height

Does that mean if I am more than 68 km from a station I can operate a fixed TVWS Base station at up to 600 meters HAAT? No.  This was what IEEE 802 proposed.  The FCC's Order referenced it, and then simply said that the maximum ground HAAT was 75 meters, full stop.  Such is the differ
