[TowerTalk] 40m 4el KLM - replacing linear loading with coils

[Robert Harmon]

How much loss is there in a conventional Yagi match ?    From what I understand the OWA has about a .50 dB loss in forward gain compared
to a conventional Yagi.  If a conventional yagi has about the same .50 dB loss in the match system then they would both have about the 
same forward gain.  Then............. the OWA is winner with its wideband SWR curve.   
Sounds like a   " If it seems too good to be true"   thing :-)
