Thanks, I'm trying to be helpful😁

Hope it's useful.

It's an amplifier..high gain and low noise, one of the best you can find ..of course it will affect RX..it will improve it for sure. A 5V phone charger will do a proper power supply.

@@viocaia ok thanks. Just wanted to make sure whether or not it needed to connect to something else in-between the antenna and radio.

@@GeorgiaRailfanner nothing else..just hook it on..

@@viocaia ok thanks.

Yes, it can be used and it's improving RX. About earnings, that's depend about the network, after my statistic like 10% of the incoming RX is turn to witness.

It's just a compare with the other amplifiers I tested..The floor noise is around -80dB...that's the reference..and peak is the noise added by the amplifier..

Not suitable, it's running from 20MHz minimum...

I'm afraid I can't...is not bidirectional

Very high gain , like 18-20dB..I got more with it and a test about gain too..

I’ll give it a try, I have bought one to see if it’s better than my Acasom RX 17 TX 6

@@Spark5 For RX it's much better..but is not a bi-directional..so it's RX only!

@@viocaia Are these suitable for Helium mining?

​@@Spark5 Perfect for RX..if you want a bi-directional there is a way with a splitter and 2 antennas..check my video about..

Yes it is!

@@viocaia can you use it to boost your cell signal

@@alfredkwawukume630 No, even the frequencies range fits under GSM but it's not bidirectional.

Right! No TX.

@@viocaia Thanks, but I do agree, it has an impressive gain.

@@Tore_Lund Ther eis trick using a spltter and two antennas, so the RX comes antenna/amplifier/splitter/miner and TX goes from the second splitter port to a different antenna out. Check my videos I have one about it.

@@viocaia I have watched a lot of your videos and I appreciate your experimental approach to everything. My interest is not Helium mining, but Meshtastic, however the RF challenges are the same. Same channels and transmit power. I live in a city, not too high up, like you. So I get most contacts max 2 km away, but occasionally from 6-13 km away, so I try to optimize my setup to best use my un-optimal location. Meshtastic is possibly not that useful for anything, but it has become an interesting hobby. The enjoyment so far, is to make QSO with strangers. Like a radio amateur, but without needing a license.

@@Tore_Lund Interesting, I'll check it out, tusen takk og god påske

It's RX only..so far is doing well , I'm still collecting data, need some time..

@@viocaia Ok, I'm thinking about to buy it, thank you Viorel😁

That's for RF signals..

@@viocaia yes I know . One aend to ant. The other to radio. But which end goes to the sdr?

@@leanlafitte OK, if you want to use it with SDR , antenna goes to antenna input of NooELec and output of NooElec goes to SDR's antenna input.You also provide power from SDR Radio if it's got Bias-T function..

Nice! I can say this is really good..For now it's in the attic connected to a miner, but I'll try it soon with SDR radio ..I need a better antenna though...

Tomorow I'll post a look inside..

@@viocaia Yeah, I would love to see real results. Nooelec is a good company but a true LNA needs to meet this criteria at its maximum (for instance the LNA for the old C band satellites was less than 45 Kelvin max at 25 degrees Celsius) is -> A typical LNA may supply a power gain of 100 (20 decibels (dB)) while decreasing the signal-to-noise ratio by less than a factor of two (a 3 dB noise figure (NF)). Although LNAs are primarily concerned with weak signals that are just above the noise floor, they must also consider the presence of larger signals that cause intermodulation distortion.

@@generalawareness101 You lost me here! 🙂 Maestro!

@@viocaia You don't have the equipment to measure how low noise it really is so a lot of companies bank on that. Lab equipment to measure the Kelvin temp added by the LNA is heavily expensive. What that leaves is hoping someone did it who has access to such lab equipment. We can measure the other two items I mentioned with equipment you already have.

Yep..to much to say in a single 10 min video..
