Review on 🔊 Nooelec Lana - High-Performance Ultra Low-Noise Amplifier (LNA) Module for RF & Software Defined Radio (SDR) with Enclosure & Accessories. Versatile Wideband 20MHz-4000MHz Frequency Capability with Bias Tee & USB Power Options. by Joi Thomas

I bought this for use with a scanner with a loft mounted antenna and a long cable. The low noise figure and decent LNA gain had a big impact on reception, for example I can now pick up the control tower of a local airport where I could only pick up planes that were previously in the air. The device is very well made. with an extruded case that houses a very nice PCB with RF electronics in another shielded case. There are options to power the device with DC power via the coaxial cable at the output connector with an external bias tee, or via the USB connector from a local power supply. However, be aware that when using the USB connection, DC voltage will be fed back through the coaxial cable, potentially damaging the connected receiver. When used with a local USB power supply, a coaxial DC power supply should therefore be used on the output side. This isn't a fault of the product and the datasheet says it works that way, but it's something to be aware of - I only noticed this because the power LED went out when I turned on the feeder connected the scanner.
