The 160-meter band is the oldest amateur band and was the staple of reliable communication in the earliest days of amateur radio, when almost all communications were over relatively short distances, and typical operating frequencies were below 20 MHz. In the UK 160 meters was the primary band used for mobile operation for many years.
As an "all-band" transceiver, the TS-2000 offers a maximum power output of 100 watts on the HF, 6 meters, and 2 meters bands, 50 watts on 70 centimeters, and, with the TS-2000X or the optional UT-20, 10 watts on the 1.2 GHz or 23 centimeters band. The (American version) radio's main receiver covers 30 kHz through 60 MHz, 142 MHz through 152 MHz ...
The T-antenna is an omnidirectional antenna, radiating equal radio power in all azimuthal directions, while the inverted-L is a weakly directional antenna, with maximum radio power radiated in the direction of the top load wire, off the end with the feeder attached. Multiwire broadcast T-antenna of early AM station WBZ, in Springfield, MA, 1925.
The antenna used for broadcasting through the 1920s was the T-antenna, which consisted of two masts with loading wires on top, strung between them, requiring twice the construction costs and land area of a single mast. [2] (pp 77–78) In 1924 Stuart Ballantine published two historic papers which led to the development of the single mast antenna.

Rebuilt in 2003, the new tower has almost the same height, i.e. 326.8 m (307.1 m for the structure, but the antenna is shorter (19.7 m)). Angara transmitter, Northern Mast, Angara, Russia June 6, 2001: Guyed steel lattice mast carrying a T-antenna 205 Deteriorated support guys World Trade Center North Tower, New York City, NY September 11, 2001
Practical antennas at these frequencies are much shorter than the wavelength, making it difficult to efficiently radiate much useful power. By current U.S. and Canadian regulations, LowFER transmitters may not have antenna and feed line lengths longer than 15 metres (49 ft), or final RF stage input powers that exceeds 1 watt. [6]
UHF (14-36): 5 MW (5,000 kW) video analog at 2,000 feet (610 meters) above average terrain; 1 MW (1,000 kW) digital at 2,000 feet (610 meters) above average terrain Notes: All full-power analog television station transmissions in the US were terminated at midnight Eastern Daylight Time on June 12, 2009.
