This is normal, but without the radials your RF is  mostly heating up the earth.   If you make the L a little longer, then insert a variable capacitor at the feed point, you should be able to find a higher feed point with the radials connected..   With trial and error 'juggling' the extra wire length and capacitance. you can get very close to 50 ohms, and get a good signal out for DX.

Hi allLast year i install an inverted L antenna for 160 with few radials different lenght.ohms was between 20 to 25 ohms and swr about 2.2 . This past weekend i was checking thethe antenna with the mfj analyser and i proceed to disconnect the radials from the groundrod and just leave the ground portion of the coax attach to the ground rod and the reading wasSWR 1.2 and 50 ohms. are this normal ?
Thanks
