Such an antenna was developed for professional communication, but then it became popular among radio amateurs.
Depending on the length of the structure, such an antenna can operate in the frequency range up to 2 – 30 MHz, that is, in almost the entire HF range. In this case, any tuning of the antenna to the frequency is not required, it works the same in the entire frequency range.
T2FD antennas are available in various lengths. The most popular lengths are 28 m (regular) and 14 m (short). But there are other lengths as well. The T2FD antenna is 28 m long and operates in the frequency range from 3 to 30 MHz, covering all shortwave amateur bands except 160 m.
But there is also an extended version of the antenna with a length of 56 m. Such an antenna is slightly less popular among amateurs due to its large size. But thanks to its size, it covers the entire HF range and allows you to work both for reception and transmission in all amateur bands. Continue reading Tilted Terminated Folded Dipole
