@Dave :
Thanks, 1.86:1 was before I put the PCB into its final plastic case. Then within the case it jumped to 2.6. That's when I calculated the corresponding matching values. I've put an 8.2nHload inductor and a 3.9pF series capacitor. The resulting reading is on the 9th picture. It jumped the other way around. I think it has to do with what Roger says.
@Roger : It took me a few reading of your two last replies but I think I got it. If I understand correctly, the shield of my coax is now integral part of the antenna system as it is connected to the ground pad which is the antenna and system ground and also the ground plane. In this case then, how will I ever achieve an accurate reading ?
Thanks
