Has gain up to about 1Ghz. Higher than 1Ghz the gain falls off to 0 gain and some loss. 2 out of 2 units same issue. This unit should have a 1Ghz spec.

When I received the LNA it was literally falling apart in the plastic bag. The nuts and washers from the SMA connectors were off and just laying in the bottom of the bag. 4 of the screws that hold the end covers on were also out. The pc board was not being held tight so the mini usb socket was not positioned correctly. I was going to send it back -- but I decided to try to reassemble it and see if it worked and if so how well. I took about 20 minutes to reassemble it. I charged up the battery and connected it in the antenna line. SUPRISE!! I hand not been able to get any audio, only squelch brakes. With the LNA in the line, I was getting several stations clear with just a little back ground noise. I am a happy camper.OK -- Absolutely no excuse for the VERY POOR WORKMENSHIP and inspections, But mine does work!! I doubt most people would try to reassemble theirs if it arrived like mine so you would probable see only 1 star from them.

I tested 2 of the amplifier using a -30dbm signal from the tracking generator flat between 2Ghz and 6Ghz. As can be observed in the picture, there is still about 20db gain at 2Ghz but there is actually loss above 4Ghz. This amplifier is the typical Chinese junk sold on e-bay and Amazon where someone uses sub par parts to clone an original design. An absolute waste of money if someone is looking for an RF amplifier above 2-3 Ghz. Moreover, returns are only good to the seller, that means you have to ship it back to China on YOUR dime. It cost more to send them back than to throw them into the trash were they belong...and I bet the seller knows that and has his business model build around that..Shame on Amazon for permitting this practice.
