IIRC, Ken Brittain (sp?), father of the "Cheap Yagi", had a mention of this in his CQ VHF column. It was noted that the original design of the Arrow apparently used a formula for insulated elements on the UHF side. This resulted in the elements being about 1/2" too short. I don't have that issue of CQ VHF with me, but it was published about 2 years ago. Jim KQ6EA

Thanks

Stephen,
Check this out:

A duplexer is built as part of the antenna
combination, but could be done
separately if necessary. Any 50 ohm coax and
connectors could be used. This one
does feature inductors wound on a pencil.
