Nevertheless, mismatch losses are a BIG deal to the cellular folks.
They do exist and can easily be seen at much lower frequencies with
cheap connectors that are not correctly designed and also if terminated
incorrectly.
Two UHF connector pairs separated by 155 degrees (worst case) of 50 ohm
cable on 70cm produces over a 2:1 SWR. Now the mismatch loss is .55dB.
This is measurable easily is very real.
