does this work in either direction? it is not labeled in and out.

As with all our devices, input is on the left and output is on the right. Thanks!

does this unit pass the bias voltage through or does it block it?

When powering via bias tee or externally, voltage is not passed through to the input of the LNA. There will be voltage present at the output when powering externally (through the micro USB port). If you need any further information about this product as it relates to your specific application, please contact Nooelec directly for support. Thanks!

Is the SMA DC block required for use with this amplifier with a Nooelec RTL-SDR?

In most cases no, but it depends on the NESDR you choose. It would not be required for the NESDR SMArt series for sure. For more information or clarification, please open a ticket at http://support.nooelec.com. Thanks!

Could I use this on a base station ham radio?

Sure, as long as you use appropriate adapters and it is within the appropriate frequency range. Note this is meant for RX only. Thanks!
