If you are not a regular reader and you have just landed on this site, to follow the thread of why I am reviewing this antenna you can start reading this note and this other one.
If you don't have time or don't feel like it, I'll summarise it for you. I got this antenna for use with a SDR (software defined radio).
Other reviewers claim just the opposite of what's described here; turning the potentiometer inside the box clockwise increases the gain (and noise floor)...
I'm not going to fiddle with it, so have no idea who's right.
Yes, finally I haven't touched the potentiometer either, and I don't plan to do so because I don't want to waterproof the box with the risk of water or humidity getting in.
The truth is that, although I have quite a lot of noise because of the thousand devices around me, the balance between noise and signal is not bad at all.
I'm already using it with the Beas Tee from the V4 and it's a relief to get rid of the power bank and two cables :P
Once again I thank you very much for the comment, I probably would have spent the rest of my life using the Bias Tee on the antenna if no one had warned me.
You do not need the little Bias Tee box that came with the MLA-30+ if you're using the RTL-SDR Blog version 4 dongle, as this has its own Bias Tee built-in. Just connect the long cable emanating from the pre-amplifier box at the antenna and connect it directly to the SMA on the SDR. Then, to activate its built-in Bias Tee, just check the Offset Tuning option in SDR#. If it is active a tiny red LED besides the SMA should light up. This simplifies the setup quite a bit. You can activate the Bias Tee also from the command prompt in Windows, using the 'rtl_biast.exe' executable.
Thank you very much for your comment, Hans
What a great surprise (and joy) you give me.
I didn't know that, and I tried to read as much as possible before buying the antenna.

I'm going to try it out right now.
