There's many great antenna manufactures making antenna's for our band, ZX Yagi now of Germany, DXSR from France, G.B Antenna's of Holland and PKW from Italy, just to name a few.

 I decided to go for a 5 element ( Super ) G.B antenna made
by George in holland.

After receiving and opening the 3mtr long package from Holland, I was really pleased with the quality of craftmanship, but this would be put to the test when building the antenna.

I liked the idea that the boom goes inside the boom sleeve (to join the  2 boom sections together). On beam's I've used in the past, the sleeve is thinner and goes inside the boom. So George's way makes a stronger boom.

While the tower was down,
I decided to upgrade the
 stub pole / rotator bearing and coaxial cable.

After mounting it on the tower, SWR could not be
 better, 1.2:1 all over our band, also 1.7:1 on or around 28.500.

Over all, I am very happy that I purchased an antenna by G.B Antenna's of Holland, instructions accompanying the antenna were easy to understand, all elements were perfectly cut, every hole for the self-tapping screw's lined up true, definitely an easy and straight forward installation.

Finally, George of G.B Antenna's was very helpful, before I ordered the antenna, I phoned him a couple of times with a few questions, we exchanged many e-mails, he phoned me to let me know the antenna was posted, in fact, I received the antenna only 5 day's after sending payment !, 
GREAT SERVICE GEORGE,
THANK YOU !.

I would definitely recommend G.B Antenna's.
