The T-antenna is an omnidirectional antenna, ... It was a multiwire 'T' with a 50-metre (160 ft) vertical wire and four 120-metre (400 ft) horizontal wires.
160 meters is populated by many dedicated experimenters [citation needed], as it is a proving ground for ingenuity in antenna design and operating technique. It also serves as a "training-ground" for the 630m and 2200m bands, where logistical and technical demands are even more extreme.
With a low power home station and a simple antenna, range would be around 50 km (30 miles). With a large antenna system like a long yagi, and higher power (typically 100 watts or more) contacts of around 1 000 km (600 miles) using the Morse code (CW) and single-sideband (SSB) modes are common. Ham operators seek to exploit the limits of the ...
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]
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 ...
T-antennas have a height between 50–200 meters, while mast aerials are usually taller than 150 meters. The height of mast antennas for LORAN-C is around 190 meters for transmitters with radiated power below 500 kW, and around 400 meters for transmitters greater than 1 000 kilowatts. The main type of LORAN-C antenna is insulated from ground.

Mast radiator of a commercial MF AM broadcasting station, Chapel Hill, North Carolina, USA. A major use of these frequencies is AM broadcasting; AM radio stations are allocated frequencies in the medium wave broadcast band from 526.5 kHz to 1606.5 kHz [5] in Europe; in North America this extends from 525 kHz to 1705 kHz [6] Some countries also allow broadcasting in the 120-meter band from 2300 ...
