Yes. 8943. The phasing network is a two stage L-network in each path, stepping the impedance down toward an antenna that is greater than 50 ohms. Seems backwards. What you really care about is minimum S11 at port 1 and maximum S21 if the antenna is port 2. I would replace S1P with port 2. Delete 8943 ports 2 and 3, and adjust TR1 ratio so that port 2 reflects as the antenna real impedance at resonance. Best S11 and S21 should occur when the phasing/matching network is optimum.
