That is a very nice construction. Do you have a RL measurement for it?
The SO239 socket really needs to be an N-Type socket. The PCB track from socket to 50R element should be 50R (3mm track on 1.6mm FG) so that ought to be OK but the measurement just done (as below) it's not as good as was hoped for, but is most likely down to the liberal use of S0239 and PL259 connectors in this test.
The sweep is 50kHz to 1.5GHz - the green smith chart line.
