SIRIO SY27-3 10/11m 3 Element Yagi/Beam Antenna,Unboxing & Assembly

SIRIO SY-27 10/11m 3 Element Yagi
This video was in the scrap pile but decided it maybe useful to someone so here it is.The Antenna works unbelievably well and incredibly well locally beam to beam.
Although it is cut for 27.500 i have adjusted the Gamma for UK40 Channel 20 which is 1.1 which moves me into 10m CW with ease and although a little high at 2.1 on 27.000mhz you will find the Gamma match is very tunable for quite a decent bandwidth.
Here are the results and element cutting measurements:
SWR,
26.500mhz 2.5
27.700mhz 2.1
27.555mhz 1.5
27.791mhz 1.1
28.000mhz 1.4
28.100mhz 1.7
28.300mhz 2.6

Each Element length for 27.500 with standard Gamma measurements is:
Reflector 2837mm
Driven 2570mm
Director 2510mm
