I have several 1 meter LMR195 pigtails from aliexpress and they all have bad SWR=1.3 at 28 MHz.
One of them has clear marking LMR195, so there is no mistake with cable type.
I tried to heat soldering points on connectors with iron in order to improve soldering quality, but it doesn't help.
Then I tried to measure cable capacitance and inductance.
Capacitance was within LMR195 specification.
But inductance was twice more higher than specification.
So I think this is just defective Chinese coax cable with wrong impedance.

I also bought several 1 meter pigtails with RG58 cable from aliexpress.
But they works ok and have SWR ~ 1 up to 200 MHz.
Just connect 50 Ohm RF dummy load on the end of cable and try to connect it to transceiver output through SWR meter. Try TX with different frequencies at 10-100W and see what is SWR. Also try to sweep it with vector analyzer. In such way you can check if your cable is usable.
