You are welcome to ask questions assuming you intend to purchase, but please refrain from negotiating prices. Immediate purchase is fine. I am busy, so I generally want to leave items listed until they sell. Thank you for your understanding. I have set the shipping time to 4-7 days due to potential business trips, but I will try to ship as quickly as possible when I am not traveling. If you are in a hurry, please confirm the shipping date with a question before purchasing. m(__)m This is a new, unused item. It has only been opened for photography and to check the serial number. It became surplus at the worksite, so I am selling it at a discounted price. If it is compatible, it's a great deal(^^) The text in the title, etc., is for reference only. Please confirm compatibility based on the product number at your own responsibility before bidding. According to the terms of DX Antenna's manufacturer warranty, the warranty ends upon transfer of ownership. Therefore, for this product, the transfer of ownership will be a suspensive sale, meaning it is conditional upon confirmation of no initial defects. In the event of an initial defect, please return the item, and I will handle the manufacturer's warranty claim. Please check the operation within 7 days of arrival. However, if the item has been disassembled, shows signs of overcurrent, or is otherwise ineligible for the manufacturer's warranty, the transaction will be concluded as is. I will only handle initial defects covered by the manufacturer's warranty before transferring ownership. I have two of these items, and I have posted images of one that I opened for photography. If you need two, please inquire via comment.
