Order processing times and shipping times:
Order processing includes: order registration after payment, adding the order to the list of previously registered orders, replenishing the product if it is not in stock, checking the product, packaging the product, preparing a shipping label for the product, and handing over the shipment to the courier.
Orders are generally processed within 3 business days of receiving payment, however, we strive to fulfill orders the same day whenever possible.
Once the goods have been picked up by the courier, it is not possible to change the shipping address or cancel the order.
When will it arrive?
Shipping and delivery times for products entrusted to the courier vary from 1 to 5 business days.
Deliveries are made Monday through Friday.
Delivery times are purely indicative and are in no way binding. Shipments are handled by external couriers (e.g., Poste Italiane Group, SDA, GLS, BRT, UPS, DHL, MailBoxes, etc.), so we cannot guarantee a specific delivery date, only an approximate timeframe.
Deliveries are subject to undetermined variations during holidays, unexpected or planned carrier strikes, shipment management issues with the courier, or significant weather conditions.
Deliveries may be delayed if the shipping company encounters management issues: e.g., misdirected shipments to other regions, lost shipments, adverse weather conditions, locations not served daily, delays during the Christmas period, delays during the Black Friday period, etc.

grazioli fe6v vertical antenna 5/8 from 50 to 54mHz power 2kw. {
{This omnidirectional antenna with a wavelength of 5/8 λ is characterized by the use of high quality and durable materials and a high resilience. The resistant AW6063-T66 aluminum alloy is used for the tubes and radials of the elements, made with particular precision. {
{The details also show 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 component 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 sheath that prevents the entry of water and humidity. {
{The High "q"
The coil plays a fundamental role in the adaptation of impedance and in the transmission of the maximum RF power. {
{q, the quality factor, is determined by the length/diameter ratio, by the distance between the turns, the material, the diameter of the wire and the presence or absence of metal nuclei. {
{In a nutshell, the greater the quality factor of the coil, minors are high frequency losses. {
{The "FE" series uses air core of particularly generous dimensions, without metal nuclei and with largely spaced spires, which allow to obtain one of the most technically possible Q's values. {
{this guarantees maximum efficiency and ability to bear high levels of RF power. {
In addition, the coil is directly connected to the ground in continuous current to ensure a significant reduction in atmospheric interference and background noise. {
{To obtain the desired "gorund plane" effect, 4 robust radials 1.4 m long radials are used with wavelength of 1/4 λ. {
Thanks to the supplied anti -corrosion assembly material, the antenna can be fixed to pylons of diameter between 40 and 54 mm. {
