I run a few dongles (NooElec Smart T dongle) off my pc connected to an Electroline EDA UG 2802. I have an LNA amp with bias t. If I mount the LNA @ the antenna, and enable bias t thru either Sdr# or Fmp24, will it work going thru the EDA UG 2802?

Probably not. Most 75 ohm equipment is DC blocking, meaning it won't pass DC voltage through splitters or drop amps, unless they are specifically labeled "Power Passing" or something like that. That is normally reserved for satellite equipment where the LNA needs to be powered over the coax. The Electroline drop amps are designed to accept DC voltage on one port in order to power the amp itself by using a power inserter on the coax before the amp. That's normally the port labeled OUT+PWR

You can put a $5 2-way splitter between the input of the UG2802 and the coax to the antenna+LNA. Then connect the NooElec to the splitters power pass port. It will be a 3dB reduction in signal so you will have to increase the LNA gain by 3dB. Any attenuators inline will have to be powerpass. It's just a simple choke, maybe 100uH or higher and 1 ampere or higher, between input and output of an attenuator that only bypass DC to 10MHz and not higher frequencies.

Well that sucks. Looked at fact sheet and did not see anything about other than how it could be powered unless I missed it or like you said, might be called something else.
That seems like the route to go with and 6 bucks with free shipping too..
Thanks guys.
