AntennaDinamica AD introduce sonn the innovative Dinamic antennas AD-Motor AD-Controller

AntennaDinamica “AD” born from the AD-Team passion, a italian group composed of experienced Ham radio Operators. Factory research located in Subbiano, Arezzo (Italy) – - See the Link and Video below !
Nasce AntennaDinamica AD per la passione della squadra AD-Team, composta da un gruppo di esperti Radioamatori. Nella sede di Subbiano (Arezzo) vengono sviluppati e testati gli AD-Motor.

The AD company introduce soon the innovative dinamic antennas products to the marketplace. – The decision was made to determine market viability by participating in the 2012 HAM RADIO trade show in Friedrichshafen De, the largest convention of its kind in the Europe.

The AD-Motor system, powered by a  NEMA 23 stepper motor, can control the element lengths, a long boom is not needed to achieve near optimum gain and front to back ratios on every frequency between 7 MHZ and 50 MHz. – The Stepper-Motor NEMA 23 has a torque 3 times stronger than of a stepper motor NEMA 17 commonly used in other dynamic antennas. – The AD-Motor Unit is a high precision mechanism made of special design and materials.

The adoption of a drive shaft bound by a bering bracket with the slide plate of the elements tapes, who eliminates any tape of oscillation making a precise engagement of the beryllium tape in the motor teeth shaft !
Another great addition is an exclusive contact between the element tape and feed line, we chose Teflon material (most slippery.. opposed to system with slat!), the electric contact between the parts is assured by a calibrated spring which acts to push the element type against one great copper beryllium plate.

The AD-Controller which is directly connected into your computer, driving you controlling all elements lenght, looking on the screen in real time the effective forward power, swr and operative frequency. CAT control included for all HF rigs, allowing great grafphic interface to take control with just one click of all functions.

Watch the AD Video:  Antenna Dinamica Motor Unit Test of 17/feb/2012

In this video we show the speed tests performed on AD Motor, we’ve tried to stress the AD stepper motor by starting from 690 steps per minute untill making him take more than 800 steps per minute – ( 650 steps! …that there was no mechanical failure)
