B07G14Q6XX Price: $19.95 Score: 1000.000 Category: Electronics Rating: 4.5 Votes: 216 Find similar products RTL-SDR Blog Wideband Low Noise Amplifier Bias Tee Powered. Includes 1x RTL-SDR Blog Wideband LNA (Bias Tee Powered) and 1x SMA male to SMA male adapter. This is a general purpose SPF5189Z based wideband LNA. Works from 50 MHz to 4 GHz with a noise figure of less than 1dB and a gain of 18.7dB @ 900 MHz. Requires bias tee power, but there is an internal header which can be used to switch to external power, although you won't be able to use the enclosure in that case. If you're looking to improve ADS-B performance we recommend our Triple Filtered ADS-B LNA. Please note again: Requires 3 - 5v bias tee power. The RTL-SDR V3 provides 4.5v so is suitable. IMPORTANT ESD NOTE: If you use this LNA placed close to an outdoor antenna, please ensure that your antenna is sufficiently grounded. There is a fast ESD diode, and GDT on the LNA PCB for dual protection, but if the antenna is not grounded the effectiveness of ESD protection components will be severely reduced, and you run the risk of damaging the LNA.

B01HYO608A Price: $19.95 Score: 5.988 Category: Electronics Rating: 4.3 Votes: 34 Find similar products Adafruit (PID 3072 RFM95W LoRa Radio Transceiver Breakout - 868 or 915 MHz. Sending data over long distances is like magic, and now you can be a magician with this range of powerful and easy-to-use radio modules. Most WiFi, Bluetooth, Zigbee and other wireless chipsets use 2.4GHz, which is great for high speed transfers. If you aren't so concerned about streaming a video, you can use a lower license-free frequency such as 433 or 900 MHz. You can't send data as fast but you can send data a lot farther.' The modules do packetization, error correction and can also auto-retransmit so its not like you have worry about everything but less power is wasted on maintaining a link or pairing. These modules are great for use with Arduinos or other microcontrollers, say if you want a sensor node nework or transmit data over a campus or town. The trade off is you need two or more radios, with matching frequencies. This is the 900 MHz radio version, which can be used for either 868MHz or 915MHz transmission/reception - the exact radio frequency is determined when you load the software since it can be tuned around dynamically. These are +20dBm LoRa packet radios that have a special radio modulation that is not compatible with the RFM69s but can go much much farther. They can easily go 2 Km line of sight using simple wire antennas, or up to 20Km with directional antennas and settings tweaking Range of approx. 2Km, depending on obstructions, frequency, antenna and power output All radios are sold individually and can only talk to radios of the same part number. E.g. RFM69 900 MHz can only talk to RFM69 900 MHz, LoRa 433 MHz can only talk to LoRa 433, etc. Each radio comes with some header, a 3.3V voltage regulator and levelshifter that can handle 3-5V DC power and logic so you can use it with 3V or 5V devices. You will need to cut and solder on a small piece of wire (any solid or stranded core is fine) in order to create your antenna. Optionally you can pick up a uFL or SMA edge-mount connector and attach an external duck.

B00FNITQRW Price: $264.99 Score: 5.882 Category: Electronics Rating: 4.3 Votes: 24 Find similar products MFJ MFJ-1026 Noise canceller, 1.5-30MHz. MFJ Noise Canceling Signal Enhancers are designed to reduce noise or interference, or improve desired signals, before the noise affects sensitive receiver circuits. Unlike conventional noise blankers, these units can be effective on all types of noise (QRN), as well as on interference (QRM) from unwanted signals. From the Broadcast Band to low VHF, these Noise Canceling Signal Enhancers work on all signal modes and can transform difficult receiving situations so you can finally hear, work, and log that rare DX! MFJ Noise Canceling Signal Enhancers allow the user to adjust both phase and amplitude while combining antenna inputs. One of two antenna inputs may be connected to the transmit antenna, and the other to an external receive antenna or the internal whip antenna on the model MFJ-1026. Or both inputs may be used with identical receive antennas to create various directional patterns for optimum results. The signal output to the receiver or transceiver is the vector addition or subtraction of signals from two separate antennas, balanced and phased. This allows unwanted noise to be removed or desired signals to be enhanced. Some other phasing systems provide either a limited phase adjustment range or change the signal's level as phase is adjusted. These MFJ units feature exceptional phase amplitude flatness making adjustments easy. Null out interfering signals or peak desired signals with the adjustment of a few controls, and pull in that station you want to hear! MFJ Noise Canceling Signal Enhancers are optimized over the range of 1.8 to 30 MHz and contain the interface circuitry necessary for operation with most modern HF transceivers. Although these signal enhancers contain internal RF sensing for T/R (transmit-receive) switching, we strongly recommend the use of the external T/R control connector on the rear panel for keying. These units run on 12 Vdc or 110 Vac with an optional adapter, sold separately.
