Fiber antenna transmitter for sale

Hello, I'm selling a fiber transmitter that I've used for only one month. I bought it for 1200; its performance is truly great. I've used it for just one month and now I want to sell it. Honestly, I don't know the current price of this transmitter. Make an offer, and whoever makes an offer, let him fear God. Honestly, I don't know its price, nor do I fully know its specifications from the device.
