Down East Microwave model 13ULNA low noise amplifier/preamplifier in good working order. I measured it to be 16.2 dB gain at 2.441 GHz at 13.5 VDC supply voltage. 1 dB down frequencies were measured to be 15.2 dB at 1.592 GHz, and 15.2 dB gain at 2.791 GHz. Covers the 2.3 to 2.45 MHz ham band, 2.4 GHz WLAN channels etc. I don't have a noise figure meter but these are supposed to between  0.4 to 0.7 dB NF, good for DX! The screws are missing from the first photo as I was about to take the inside photo. Manufacturers specifications are at http://01895fa.netsolhost.com/PDF/13ulna.PDF. This one has SMA connectors. They go new for $120.00 and a 4 to 6 week wait they say; http://fwfvq.tehfm.servertrust.com/category-s/1839.htm Shipment only in the USA. Thanks for looking.
