All, This does not seem right..

Powered on??
ANT to XCVR=? -50DBM to -35 DBM? ( 2 Mhz,30Mhz)
ANT to SDR= -2dbm across frequencies 2-30 Mhz??

Power on in TX

Ant to XCVR=? 0DBM
Ant to SDR=?? > -60 Dbm across? band? 2-30 mhz

Question is WHY is there a 2 DB Loss from ant to SDR in RX ?? ? and why is there a -50 db loss to XCVR port..?? Seems that it should also be 0 dbm for both..

HELP?

Please forgive my ignorance, can you explain what this is?

OK? This the loss between the ports..? so power on? (? Not in TX )?

From ANT connection to the SDR? it has 2 db of loss? should have? 0 DB? or no loss ( shorted )

From ANT connection to the radio? its shows -50 db of loss? or you could say open? no connection..

So when the sdr is receiving the radio is not receiving at all .. ?

when in TX? it seems to work right?
Ant to XCVR ( radio) =? 0DBM? or shorted?
Ant to SDR=?? > -60 Dbm across? band? 2-30 mhz? or open

my question is? why 2 db of loss should be shorted .. or no LOSS
