WELL worth the low price!!!!!

Just purchased my 4th one. These LNAs are great for general purpose reception. I've added one to my weather sat station, my portable SDR box, a quick attachment for receiving on my HTs and my ADS-B setup! Easy to mod and to integrate into an RF chain. Though it's easy to add an LED indicator, would be great if one were on the board. Or if LED footprint were on the board.

Wide band Amplifier board works perfectly in HDTV applications

The media could not be loaded. This wide band amplifier board works perfectly in my HDTV application. I had good but marginal signal, but found this model and I now have 99-100% signal all the time.Add your own SMa connections anf 12v power supply and battery connection.Less than 1/2 the price of a commercial preamp but does not overdrive TV TUNER. Very wide band performance.Highly recommend .

Works great for h d t v signals.

I like to put my own amplifiers together in this case. This work really good i'm pulling in the weaker t v signals.

Good all around basic amplifier.

it does its job, it is a general purpose amp so do not expect ultra low noise and don't expect a very flat gain curve either. But, as a general purpose amp it is unbeatable for that price.

Good Value and Performance

I have purchased two of these. The first is used for the 137 MHz NOAA weather satellites. I mounted it in a small box and attached it just beneath the antenna. These easily boost the signal to an RTL-SDR V4 software defined receiver for good reception of the NOAA satellites. The second one I am keeping as a general purpose wide band preamp for my discone antenna. I use a homemade bias-T to supply 12 VDC through the coax to these preamps. Would highly recommend.

Shielding of the amplifier preferred

No metal shielding, need to solder power supply wires, so they costs less, and less useful. I haven't tried them, but another one with shielding, and that one does not require soldering of power supply wires. I'm going to get narrow band pass filters first, otherwise too many strong signals would be amplified, like TV, FM brodcast signals, causing saturation of the amplifiers. ( this is not the problem of any amplifiers, but the environment )Shielding of the amplifier preferred, and somehow the input and and output should not cause coupling to avoid internal positive feedback, causing undesired oscillation, making them useless.

Worked, but should be shielded.

Circuit worked well, but needs to be in a metal case.

For less than ten bucks, I doubt you could find anything better.

FORIOT 9-12V Radio Frequency Wideband Amplifier Low Noise Amplifier:The FORIOT RF amplifier comes as an exposed circuitboard with two SMA connectors, one for input and one for output. It also has bare solder pads for DC power input, which can be anything from 9V to 12V. The amplifier supports an operating frequency of 0.1-2000MHz, which covers most of the common bands used in radio communication. The amplification gain is 32dB, which means that it can increase the signal power by about 1600 times. That's impressive for such a small and cheap device.The amplifier also has a low noise figure, which is the measure of how much noise it adds to the signal. The lower the noise figure, the better the signal-to-noise ratio. The FORIOT RF amplifier has a noise figure of less than 2dB, which is very good for this price range. The maximum output power of the amplifier is 13dBm, which is about 20mW. That's not a lot, but it's enough for most applications that require low-power RF amplification.The amplifier is easy to use and install. You just need to connect your antenna to the input, your receiver to the output, and your power supply to the DC jack. You don't need any additional components or adjustments. The amplifier will automatically adjust the gain according to the input signal level. You can also use a lithium battery to power the amplifier, which makes it portable and convenient.The FORIOT RF amplifier is not without its drawbacks, though. One of the main limitations is that it is not a bidirectional amplifier, which means that it can only amplify the signal from the input to the output, but not the other way around. This means that you can't use it for transmitting signals, only for receiving them. Another limitation is that it is not a selective amplifier, which means that it amplifies all the signals within its frequency range, regardless of their source or quality. This means that it can also amplify the unwanted signals and noise, which can degrade the signal-to-noise ratio and cause interference. You might need to use a filter or a tuner to select the desired signal and reject the unwanted ones.Overall, the FORIOT RF amplifier is a great product for its price. It can amplify a wide range of signals with high gain and low noise, and it is easy to use and install. It can be used for various RF receiving front-end applications, and it can improve the communication distance and reception quality of weak signals. Yes, you may need to cobble together some kind of case and do some soldering, but for less than ten bucks, I doubt you could find anything better.
