Topband: The band sans noise

[ON4GPE]

Hi Bob and all,

I'm also interested in your experience on the waller flag.
i don't know what to build , a single loop (rotatable flag) witch is not 
so difficult of course or a waller flag.
So all info is welcome.

sorry for my english, my home language is dutch hihi
