After reception of your Inquiry, we will send you an Option Sheet, depending on the product are willing to buy. In this sheet you have to fill in the dedicated options that will match your configuration requirements. E.g: for an antenna system, you would have to precise the required frequencies, if you want a UHF or VHF system, or if you want a monopole or dipole configuration. After reception of this filled in Option Sheet, we will send you a Quotation. Upon approval and reception of a Purchase Order, you will receive from our side an Order Confirmation, which is a summary of your purchase. The day this confirmation is sent will be taken as the lead time reference date. Usually, you will also get, together with the Order Confirmation, an Invoice including our banking information and allowing you to perform your first payment.
