>Greetings from Korea. I recently subscribed to the list.
>I installed a half wave length Zepp (over 80m long) for 160m
>on the top of 20th floor aprtment house and I fed it by 450 ohm
>ladder line(ready made one) with end-feed style because
>center-feed is little bit difficult for my location.
>I tried to tune the zepp with my homebrew tuner for all HF bands.
>My tuner has "SPC" transmatch configuration with 4:1 toroid core
>I found out tuning avove 40 meters are impossible.
>I believe this kind of antenna configuration needs real balanced
>tuner with capablity of switching between serial and parallel
>tuning according to the impedance of each bands.
>I tried to find out any references for this situations, but failed.
>Does anyone can comment me? Any Inernet sources for constructing
>such kind of tuner?
