John,
Do a Google search (Hidaka+V-33+yagi+manual) on the correct spelling Hidaka.

Here is an excerpt from VK6IA web page:

The Triband Yagi - Hidaka VS-33 is the Japanese version of the Hy-Gain TH3.
It has proved to be a great performing antenna with good gain and a nice
front to rear/side ratio.

Hope for your sake the VS-33 and the V-33 are the same animal!
Maybe an email to him may prove fruitful.

purchased a unit second hand. Working ok except for 14mhz . Anybody
with experience in fault finding on these units ?. How do I know the
guy I bought it off put the correct traps on the correct poles ?.
Are there only two sizes of traps (6 in all) ?. Large one on the
inside and the small one on the outside ??.
Trouble reading the directions in Japanese ...

Thanks
