Hi all,

I just finished setting up my vertical antenna for 160 in 3V8SF 
location. It is 17m (55 ft) long with 2 top loading wires 12m each 
(40ft), angle to vertical about 40 deg. I added 8 radials, 20m each 
(65ft).
With no shunt matching, the SWR at antenna base is 3.2 and at radio side 
is 2.8. Is there any way I can improve the SWR further?

Photos of the antenna along with SWR curve can be found here:
