Dan,
This is a good thing. Your system is becoming more efficient - this is what
you want. If you desire a better match, you will need to use some sort of
matching system at the base of the antenna. The SWR will continue to rise as
you add more radials, however you will reach a point of diminishing returns.
If you can get to about 16 radials you'll have a decent setup that will
result in fun on topband. Even eight will work with good results.

Subject: Topband: Inv-L swr changing when adding radials
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...
