Topband: HF-2V

[Thomas Damboldt]

Hi all,

can somebody explain to me please, how the Butternut HF-2V (with TBR-160) actually works? I was able to figure out the "diagram" of those L's and C's but could not work out whether they are traps or what? 

Is there any way of improvement other than adding top loading, e.g. placing the Ls and Cs higher in the structure or increasing the length of the bottom tube? 

Thanks and 73
