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 27.555. 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.

just email me.

Re: Syrio 4 element yagi
For nice SWR with 11 Meter Beam (Sirio SY-3 oder SY4...) use this Table:
Less Bandwidth = More Gain
More Bandwidth = Less Gain
I use on my self built Beam 1:1 Balun (Fritzel)

Re: Syrio 4 element yagi
HI, Thanks for the reply, nice photos and a good balun. I am using a none iron ferrite core 1.1 balun, can handle up to 5kw. I have vswr of 1.1 50 ohm and 0 impedence at 27.555.
Andy. I have approx 6 boom to radial syrio brackets if anyone wants them for a project, as new with the grub screws. just email with details.
