Description
From the sellerThis rf preamp hasn’t been tested. But it’s +28 VDC power through the co-ax connector on the red/ output side. The came from a company call O.N.I. Offshore Navigation Incorporated years ago. The frequency I believe was around 220 MHz. It has 2 stages of amplification, so it could be 40 db gain. I cannot prove this. It might work or it might not. It does have input protection. Sold as is. Thank you.
