🔌 Enhanced Performance: RTL-SDR Blog Wideband Low Noise Amplifier with Bias Tee Power Review

I only used this thing four or five times before having to go back for a couple of weeks, it was separate from each antenna but in circle with mine RTL SDR unit when I got back home it stopped working, actually hampered reception. and yes, I recorded offset t on RTL SDR. I don't know what went wrong but I don't have the time or equipment to fix it. I'm not sure I would buy this again, but then again I'm not sure what else is compatible with my SDR.

So far this is a working amp that was badly needed in my area. The amp arrived part assembled when offered for sale turnkey, with a few screws in the stationary packaging and another cross-threaded. I needed this so I fixed the amp after the build was complete and I have a re-thread kit so I fixed it quickly and it's running now. However, if you're looking to buy this amp, I suggest going to the manufacturer's website and ordering a kit so you don't have to worry about accidentally assembling…

When I received this LNA, two screws on the case were not installed and were hanging in an anti-static bag. I hope the quality control of the internal electronics is much better than the assembly. However, it works. I'm using it with my RTL-SDR dongle fed from a bias tee and the noise level has gone down and I can now distinguish voices with weaker signals much better. It works as advertised, although I would like the frequency response to cover the highs as well. I could buy one of the Chinese

As there are no instructions, some adjustments need to be made to get the best results.1. Connect it as close to the antenna as possible and as far away from the key as possible.2. If your software supports it, turn off LNA on your dongle if you have one. (RTL-SDR V3 has one) I used it to decode ADS-B and had to switch from dump1090 to rtl1090 and the difference was amazing. dump1090 gave me about 10 planes with a max 50 mile radius, I switched to RTL1090 and now I have an average of 20-30…

This LNA is easily damaged by ESD and should have ESD protection on the input when used with an antenna that does not have a loop that otherwise does could cause a short circuit such as a bent dipole, J-pole or balun in front of the input. Examples of antennas that can have an ESD problem are discons, long wires and dipoles - any antenna where the two legs of the antenna cannot "short". from any electrostatic charge. The static reaches a point where it can arc and burn out the amplifier chip…
