How to connect to RG-6 cable?

I think the best way would be to get an SMA Male to UHF Female (SO-239) adapter or cable assembly. And then put PL-259 (UHF) Male connectors on your RG-6.

I just don't want any additional wires. Will this work with Bias Tee?

1. The Bias Tee needs to supply a minimum of 8v at the LNA. This typically means injecting 9-10v at the Bias Tee unless it's particularly close to the LNA. 2. The RF Out center pin needs to be tied to VCC. The shorter the wire the better.

What amperage would be safe for this device?

The current draw for this device is in the milliampere range, 41 mA is what I measured.

What is the noise figure of this low noise amplifier? The most important specification of a low noise amplifier is its noise figure not its gain!

Don't know the noise figure. But just the amplifier alone (no input signal) raises the noise floor of my SDR receiver by about 13 dBm at 30 MHz. Probably not too good at VHF/UHF but no problem at HF. Hope this helps.
