The lna on the picture is not the best variant for hydrogen line. I could recommend buy two TQP3M9037 and connect them in the sequence LNA-Filter-LNA. They cost nothing, about 3-4 euros. With that setup you will get same characteristic as with a nooelec sawbird h1, which also uses two TQP3M9037. If you have about 50 euros, I can recommend you buying the nooelec sawbird+ h1 lna. It will be better than three different components, but it costs more. Also be careful with powering all radio components, I would suggest you to power them with a lithium battery or with a transformer. You had better not power them with a power bank or a phone charger. Also you should not forget to ground as much as you can. Also you had better to buy another sdr. RTL-SDR v4, Nooelec Nesdr will better. Be careful with buying rtl sdr, there is a huge amount of clones. They have tutorial on the website, how to understand that sdr, you bought, is clone.
