UHF to BNC Adapter
$6.95- Adapts a BNC Female to accept a UHF male connector (PL259).
While UHF connectors are not our favorite at higher frequencies, we also know there are some who will want UHF adapters, so we will sell these for those who want them (see note below *). These will also work fine for the Spyverter.
* Due to the wideband nature of the SDR units, use of UHF connectors is highly discouraged if you intend to use the unit above 500 MHz. Why? UHF connectors act like a brick wall to RF signals at higher frequencies, and we want you to get the most out of your SDR receiver.

Wideband 0.1-4 GHz Preamp
$45.95- Wideband Preamp for general use.
- Fully compatible with Airspy.
- 100% compatible with the Airspy bias-t. (no external power required, but power can be applied via the USB-C connector)
- Approximately 20dB gain.
- Low 0.75dB noise figure (NF).
- Manufacturer's website
- Note: This item was custom made just for Airspy.US.
This is a cost effective SAW based unit which give excellent performance gains.
All Uputronics preamps are compatible with most USB SDR Dongles such as the Airspy. You can power them from either bias tee (This item is 100% compatible with the Airspy bias-tee) or a simple USB minicable (Purchased separately). Bias tee/USB voltage is 5V max.
This unit is a small filter and preamp designed to go between a software defined radio receiver and an antenna. Using a SAW bandpass filter and a low noise amplifier (LNA), it stops out of band intermodulation while providing additional gain for increased sensitivity. The LNA is before the SAW filter. To block strong commercial FM signals a high pass filter is installed before the LNA.

z(DISCONTINUED) 145 MHz Filter/Preamp
$59.95Uputronics filtered preamps for improved reception on 145Mhz.
This is a cost effective SAW based unit which give excellent performance gains.
All Uputronics preamps are compatible with most USB SDR Dongles such as the Airspy. You can power them from either bias tee (This item is 100% compatible with the Airspy bias-tee) or a simple USB minicable (Purchased separately). Bias tee/USB voltage is 5V max.

Using a SAW bandpass filter and a low noise amplifier (LNA), it stops out of band intermodulation while providing additional gain for increased sensitivity. The LNA is before the SAW filter. To block strong commercial FM signals a high pass filter is installed before the LNA.
The LNA used is a MiniCircuits PSA4-5043+ which provides at least 21dB of gain. To stop out of band intermodulation a 145Mhz SAW bandpass filter, which has a 7.6MHz bandwidth is also present. The insertion loss of this filter is approximately 1.4dB, which does increase the overall noise figure of the unit to 0.75dB. Connectors are SMA female both sides.
