Is an LNA needed for Meteor satellites?

I want to receive Meteor M2-4 satellite images with a V dipole antenna tuned to that frequency but I want to know if an LNA is needed for a good image.

I'm in a small town and have a clear view of the sky in my backyard, there is a few buildings around but no weird signals.

If it is needed, does anyone have a recommendation?

Meteor satellite reception issues

I've been trying to get weather satellite images for a few weeks now, specifically Meteor M2-3 and Meteor M2-4. I used a lot of weird antennas:

  • TV Antennas
  • One rod bundled antenna
  • A weird old indoor Metronic TV/Radio antenna (marketed as VHF/UHF)
  • A roof-mounted omnidirectional FM Radio antenna (marketed as 80-100mhz) that works with air controllers rambling, ATIS and even 1090 airplane info

I bought the Nooelec RTL-SDR SMART V5 with the antenna bundle, some of my SDR++ settings as well:

  • 38db gain
  • AGC off
  • 2.4mhz MSPS

I'm in Croatia and dont know what's the problem, it can very likely be my antennas but I'm getting not bad signal but NOTHING at all! Is it the SDR thats the problem?

I tried a lot of passes: 40 degree ones, 80 degree ones, 85 even... (using N2YO)

I did use correct frequencies, but the entire 137mhz band was full of nothing..

I also have a weird setup: TV port>F-type>SMA

All of the antennas mentioned got at least something: FM Radio, airband traffic controllers, ATIS, 1090 plane info...

Can anyone immediately spot a problem or a config issue?

Btw I'm fairly new to SDR...

What to do as a beginner in SDR?

I just ordered a Nooelec RTL-SDR V5 because i wanted to try out SDR for the first time as I explored almost every corner of technology except radio stuff!
I chose the nooelec because the RTL-SDR Blog V3 was unavailable and the V4 was a bit expensive for me, and I've heard that the Nooelec is basically the same as the Blog V3 but with little worse HF stuff

Anyways I'm a total beginner and want to know the project possibilities with my SDR!
I know antennas are really important, I have an "Omnidirectional FM antenna" on my roof, i know it does 80-ish to 100-something Mhz, I also have your typical standard TV antenna on the same roof and I also have a satellite dish for satellite TV which I assume is unusable as it only points to 3 satellites: Astra, Eutelsat 16A and Hotbird... I also got the crappy bundled antennas. Also I checked out my infinite basement and found a so-called "Bunny antenna", basically 2 extendable antennas in a V shape, its a weird Italian indoor antenna that has a dial, the closest i found is this: https://www.epostshop.hr/UserDocsImages/proizvodi/metronic%2041.jpg
At first i thought it was just an amplifier but i think it can be used as a normal antenna if its unplugged from power

So, what projects can i do with this weird setup?
