Symmetrical T Antenna
A Symmetrical "T" Antenna is recommended for use with a 500 - 1000 watt transmitter if sufficient land is available. This antenna requires a plot of ground approximately 150’ x 400' for a 60 foot high antenna to 150' x 500' feet for a 120 foot high antenna.
The standard Symmetrical "T" Antenna is supported by 60 foot above ground level towers, or poles, placed 300 feet apart and has a 55 foot vertical radiator and a 2 wire 280 foot horizontal top hat. Range depends on the field strength required, the ground condition, and the power radiated.
The power radiated increases with frequency, however, the propagation loss due to ground condition decreases with frequency. For a 70 uV/m field strength, the range over "good" ground varies from approximately 60 miles at 190 KHz to 70 miles at 535 KHz with a 50 watt transmitter and approximately 80 miles at 190 KHz to 90 miles at 535 KHz with a 100 watt transmitter.
Optimal land based antenna system when adequate space is available.
Anti-Ice Insulator is optional with Symmetrical "T" Antennas
