I think it might be me several have asked about. I used TA 33 jrs because
they were available to me but sr.s are the same basicly.
With a 12-14' boom 3 ele. are not practical. However 2 ele. spacing works
OK. Use ARRL ant. book or Cebik or W6SAI. I used the split fed driven ele. as
Mosley does. I removed the traps and adjusted the lengths. I prefer driven
ele/ reflector design. The 17m ele.s. got a bit droopy so I used a truss of
parachute cord.
It's not a 3 ele Steppir but you can gain an S unit or two on the rest of
the pack using whatever ant. they can get the tuner to match on the WARC bands.
This works with other surplus yagis or quads. An 11m Moonraker can become
several 12m quads/yagis or donor alum. for another band. The tribander surplus
traps might become part of 40m rotatable dipole. Maybe. A 3 ele. surplus
tribander or 11m yagi might become a wide spaced 6m yagi.
Price a commercial WARC yagi and you may not think home brewing is such a
bad idea.
