SAWbird+ NOAA - Premium Saw Filter & Cascaded Ultra-Low Noise LNA Module for NOAA Applications. 137MHz Center Frequency

The best APT filter amplifier available for SDR receivers. Plug & Play with no need for software or hardware adjustment. Can be stuck with other filters to eliminate FM broadcast or pager interference. One caveat, they need to be supported.. do not stack them hanging in mid-air otherwise the connector's may break.

Perfect LNA for 137mhz stuff - sadly most of the NOAA birds are dead, but meteor still works.

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.

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!

Product arrived as promised and works as specified.

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.

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

Bad news first: (1) It's too darn expensive for the minimal amount of use I get from it. (2) The extra gain that it provides over their non-sawbird LNA, wasn't worth it to me. Good news: (1) True filtering, it really cleans up the segment it is designed for. (2) Although not superb amounts of gain, if you're serious about this frequency segment, get this LNA, it works. Honestly, the reason for the 4 stars is the price. Would I buy it again, not this frequency segment, but I am not dead set against purchasing one of their other sawbird+ LNA's.

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

Gebruikt voor de ontvangst van noaa weersateliet niet lang plezier van gehad eerste unit werkte niet bij aankoop weer een nieuwe besteld deed het na een dag al niet meer. Vind het een slecht product behoort gewoon na behoren jaren te werken .

Absolutely awesome piece of electronics 💯👍🇦🇺

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.
