Topband: Inverted L Radials

[james soto]

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
