Continuous Tuning Antenna Mod. D2T

Very new conception antenna, a Giovannini’s " INVENTION " , revolutionary and properly fit for much restricted spaces. The D2T antenna has been designed for all those who have not enough space, or those who don’t want to install, even if they have space, antennas of medium-large dimensions. This antenna permits to connect the whole world, 80 m included. Connections of 1000/2000 Km are possible in 160 m.
D2T is the exceptional compromise always sought for and never found. D2T = 11 antennas in one only ( 160 – 2 m ) plus all intermediate frequency, and with one RF cable.

SYNTHETICALLY THE BEST QUALITIES OF THIS ANTENNA ARE:
MUCH REDUCED SIZES, LIGHT WEIGHT, CONTINUOUS COVERING ON TRANSMISSION AND RECEPTION FROM 1.5 TO 200 MHz, 1 KW PeP, FEEDING WITH ONLY ONE 50-OHMS RF CABLE WITH NO HELP OF REMOTE CONTROL IN 1.5 - 200 MHz SPECTRUM TO CHANGE FREQUENCY.

DESCRIPTION:

Nonresonant high-impedence antenna composed of two dipoles folden fed and dephased by 180°, with non-inductive terminating resistor and broad-band RF transformer for feeding with 50 ohms cable. It shows a bidirectional directivity just starting from 10 MHz with 10 db F/S. When at 21 MHz it gains 3 dbd with 5 db F/B and 10 db F/S to reach a progressive gain of 6 dbd at 30 MHz with 5 db F/B and 20 db F/S. In VHF it shows a daisy-type irradiation lobe. Up to 15 MHz the signals transmitted and received are attenuated according to the graphic yield illustration.
THE ANTENNA HAS AN EXCEPTIONAL EFFECTIVENESS UNDER 10 MHz AND IT PERMITS AN EXCEPTIONAL LISTENING WITHOUT NOISE .
IN ORDER TO ITS OPERATIVE YIELD IN THE CONNECTIONS, THE ANTENNA DOES NOT SUFFER MUCH THE GROUND PLANS AND FOR THIS REASON IT CAN BE INSTALLED FROM A MINIMUM OF 3 m ( 9.8 ft ) HEIGHT.
