Sirio SY-4

We decided to try a Sirio SY-4 a few weeks back and had nice results.
4 element yagi on a approx 16 ft or 5 meter boom length .
I took it right back down as too much windload with all the other antennas on the ham radio tower .
SWR after minor adjustment was less than 1.2-1 across ch 1-40 on USA band. Nice front to back and side rejection in the 5 hrs it was up. I took it back down till next spring when the Taller tower gets redone after 25 years up in the air . I re did the smaller tower this year and added a HAZER Tram System as seen in pictures.
We was lucky enough to catch a band opening comparing our IMAX 2000 with top at 60 ft to the SY-4 at 51 ft .
4-5 S unit difference in the band opening with SY-4 Superior.

Hi William,

Welcome to the forum. Great username :-).

I have a Sirio 4000 Hi-Power antenna that I used on the CB / 11m bands and it works so well I have kept it for 10m use. They make good quality antennas at very good rates...

Well made the Sirio antennas and indeed if there are any troubles with it then Sirio have a great approach to aftercare. As Dave says, welcome here to the forum and great success with the antenna.
