Syrio 4 element yagi


I have just rebuilt a Syrio 4 element onto a 30mm square boom, Also changed the element positions, junked the Gamma match in favour of a Hairpin match which is easier to tune for the 50 Ohm and 0 Impedence at [sign in to see URL]. Got a much better bandwidth also.
 I have now have spare boom to element clamps if anyone would like these. Or I can give you dimensions for a full rebuild. All elements were insulated on the rebuild.

For nice SWR with 11 Meter Beam (Sirio SY-3 oder SY4...) use this Table:

I use on my self built Beam 1:1 Balun (Fritzel)
