Grazioli MV6 Vertical Antenna HF 6 bands of 20, 17, 15, 12, 10 and 6 meters. The antenna consists of a central radiator for the 20 m band, flanked by 4 side resonators for the upper bands. The mass plan is made up of 4 horizontal radials of length equal to 2.7 m. Side resonators are kept in a parallel position to the main radiator with non -conductive spacers, while the conductive connection is at the base close to the power point. {

For the tubes of the elements, made with particular precision, the resistant AW6063-T66 aluminum alloy has been used. {

Even in details it can be seen that the manufacturer is beating new roads instead of relying on standard solutions: for example, the antenna connector is not a standard SO239 socket such as that used by most manufacturers, but a piece developed and produced by Grazioli herself. This reliable connector has a real characteristic impedance of 50 ohm and is designed for frequencies up to 500 MHz, enduring high levels of continuous RF power. {

The housing is made of nickelated brass CW614N, while the PIN is 24 -carat gold plated to avoid oxidation and is equipped with a PTFE insulator that maintains its centering and elasticity to avoid contact loss. {

The entire group is protected by a special elastomer coating that prevents the entry of water and humidity. {

The supplied anti -corrosion assembly hardship allows you to fix the antenna with poles of diameter between 40 and 54 mm. The antenna should not be connected to a cable, so it is possible to use it in limited spaces and is easy to install. {

The MV6 is powered directly without the use of impedance transformers who would introduce losses and limit the applicable power; It is equipped with a high impedance unit that creates a continuous current short circuit, dispersing on the ground any ailments caused by atmospheric events and/or electrostatic discharges. {

The tuning is carried out by adjusting the length of the telescopic parts of the radiators and the main radiator; Each band is independent and does not interact with the others, with the exception of the 17 m band (18 MHz), which also determines the resonance of the 6 M (50 MHz). We recommend the use of a graphic antenna analyzer that makes tuning much easier and more comfortable. {
