SAWbird+ NOAA is a self-contained LNA module that allows you to capture beautiful weather images from NOAA satellites. It has very high attenuation outside the 5MHz bandpass range, centered around 137.5MHz, and a minimum gain of 30dB within the bandpass range. The rated current consumption is 180 mA.
The SAWbird+ series contains two extremely low noise LNAs arranged around a specially designed high-performance SAW filter with the desired frequency. Each LNA module has 2 EMI shields to separate each sensitive LNA from external interference. M3 mounting holes are also available to mount the PCB in your custom case or project using standard hardware.
Each module offers 3 different power options, but you should only use one power option at a time! The recommended power supply via the SMA output port (for bias - T - capable SDRs such as the NESDR SMArTee) is 3V-5V DC. If you don't have a bias-T enabled SDR, you can also use the external power options via the micro USB port or the power input head (0.1" socket). The recommended external power input is 3.3V to 5.5V DC.
Although the SAWbird has a protection circuit for surge conditions and voltages of up to 12V DC should continue to work and do not damage the device, use for a longer period of time is not recommended. Conditions would not fall under the standard 2 year warranty.

Good for 136-139 MHz. Good signal from Meteor M2-3, my QFH syncs when it’s 5 degrees above horizon.

Works very well. I use this with my SDRPlay RSP1B for NOAA and Meteor weather satellites. Did have two small issues with it.1. Caused a local FM Broadcast staion near me to overload my receiver. Used a Nooelec Flamingo BCFM filter to resolve that.2. Since its the SAWbird+ it drew more current than my RSP1B would deliver so I had to power it via USB. I would recommend, if you have the same receiver, to get the SAWbird NOAA (not the plus version), its current draw is lower and the SDR has no problem with it.

This performs pretty much as the datasheet that Nooelec publish. Gain is high, and the passband follows what they say. It's very sharp on the lower side, providing strong attenuation to airband and FM broadcast, but rolls off more gently on the other side, still allowing some of the very strong 153MHz pager signals through.Realistically, I'm not sure the LNA is needed. I get reasonable signal strength for NOAA satellites with just a V-dipole. The high gain means I'm brining up the noise as well as signal, and it's overwhelming rtlsdr dongles. Just a filter might work better for me, but your mileage may vary.

It reduces FM radio and air band around 10dB, and now I can receives good NOAA images under 30 degree elevations which is impossible before I install this LNA!

I had another companies wide-band , unfiltered LNA working. I bought this hoping that perhaps some of the noise in my images might bet filtered out. It works. but produced images of less quality than my other LNA. I probably don't have a problem with nearby AM or FM stations and when I use filters my images just get noisier because the signal is weakened. The SAWbird also caused my RTL-SDR dongle to get too hot. I could fix that by clipping a sheet of foil onto it as a heat radiator. I am using a horizontal V dipole, perhaps this would work better for some urban dweller and or a QFH-type antenna.

Low-noise amplifier with the filtering lower-cost SDRs need for best results. Nicely packaged.

I was having problems copying NOAA weather satellites due to nearby strong signals. This SAW filter and pre-amplifier has completely eliminated the problem. I was able to place he Sawbird unit in a weatherproof box at the antenna and power it through the coaxial cable with the bias-t feature. It works great.

I have this installed on my roof (inside a waterproof box). It's been running all summer in pretty extreme heat with no problems. I have it hooked to a Raspberry Pi, RTL-SDR and QFH antenna for receiving NOAA / METEOR weather satellite images. I would definitely buy this again.

De service van Nooelec vond ik goed. Ze hebben erg hun best gedaan.Maar het product maakt niet waar waarmee geadverteerd wordt.

Great preamp. Use it with a RTL-SDR. Get fantastic horizon to horizon images. Must admit I am currently using my 2meter cross yagi. Bought it to replace a blown antenna mounted preamp on my Quadrifilar Helix. As soon as I figure out a good waterproofing technique I will get up on the roof and mount it close to the omni helix. Right now I have it connected directly to the RTL-SDR dongle. WA8EBM

Make sure you install this in the right direction. It isn’t obvious. The white light will go on when it is installed in the right direction.SDR sharp shows significant increase in gain and the images come through very crisp. I use this with RTL SDRv3 and enables bias tee using their Windows application. If using with SDR#, close SDR# before launching rtl_biast.exe. You will probably have to change the device ID from 0 to 1 like I did. If it works then you will get Found Rafael... message then the program quits. Plug in the LNA and the light should turn on. That’s it.
