Product description

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.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days โ€” so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
