Hello,

If you don't have a highly tuned high dynamic range system, anything that you 
do AFTER the LNA should be OK.

For measuring purposes, a simple resistive (6dB) divider is the best.

If it weren't about measurement, I would say, just splice together the cables, 
the 1:2 SWR on RX wouldn't be a problem just for listening...

But if you want to measure tenths of a dB, you will need a real splitter, and 
the resistive one will be the most accurate.
