I installed an Inv-L for 160 of about 134ft , ~72 feet vertical , when i 
checked the SWR initially it was about 1.2:1 , then when i connected the ground 
rods it rose to 1.5:1 , today I added the first  2 radials and the SWR is now 
2:1. The antenna is being fed directly , my question is basically what is this 
telling me ?  I assume I need to change the way I am feeding the antenna and 
possibly change its length.

any help appreciated...
