[TowerTalk] Multiple HB9CV on a shared boom

[Rudy Bakalov via TowerTalk]

I was wondering if anyone has experience with building a 3 band HB9CV on a shared boom. Basically, 3 separate antennas nested into each other- 20m, 15m, and 10m.  My thought is to use coax for the phasing lines and a non-conductive boom so that there is no feed/phase line interference.

The antenna will be fixed and suspended by ropes so the non-conductive boom is not a structural issue.

Thoughts?
