The D2T is a non-resonant high-impedence antenna, composed of two folded dipoles dephased by 180°. It has a non-inductive terminating resistor and broadband RF transformer fed with a single 50 Ohm cable. The D2T is bi-directional starting from about 10MHz with 10dB F/S. At 21MHz it gains 3dB with 5dB F/B and 10dB F/S, and progressively it reaches 6dB at 30MHz with 5dB F/B and 20dB F/S. At VHF it shows a daisy-type radiation lobe. Up to about 15MHz both the transmitted and received signals are attenuated
