[TowerTalk] Triband directors

[Barry Kirkwood]

Have been fantasizing about next set up when I return to ZL.
Thinking in terms of tribander, need to conserve weight and expense.
Question:
What is opinion on configuration as used in early TH-5 : Trap triband
reflector element at extreme front of beam, additional ten metre director
between DE and triband front element.?
This gives three elements : Ref, DE, Dir on 20 and 15,  four elements Ref,
DE, Dir1, Dir2 on 10.
My concern is that the 15m resonance of the triband director could
compromise 10m operation.
Any thoughts?
