Since your reply (originally an "answer") to Lorenzo included a new photo and clarification of your actual question which will be important to anyone else who is trying to help, and since it was not an actual answer (by Stack Exchange rules), I have moved it to become an edit to the question. There is more explanation of site rules & etiquette in the tour and help center. Also see my comment on Lorenzo's answer here. Thanks. | |

| Oct 14, 2021 at 7:33 | comment | added | Lorenzo Marcantonio | Your best bet is to tune everything up to the SMA to 50 ohm. Then you put a compensating element at the base of your antenna (maybe a simple element will suffice from 791 to 960Mhz) to obtain an 'antenna assembly' tuned to 50 ohm and add coax from there. Otherwise the resulting impedance will depend on the length of the feed line which is ugly (it actually has uses in microwave:D). Search for multi-junction transmission lines for the ugly math | |

| Oct 14, 2021 at 7:15 | comment | added | Andy aka | "Any antenna" does not mean 50 ohm. In fact most antennas will not be 50 ohm. A quarter wave monopole is 37.5 ohm resistive and twenty odd ohms capacitive. A dipole is twice this amount. You need to be clear and think more about this. | |
