Was wondering if someone has a Duplexer? *IE a Box, on 1 nd is where the Coax gets connected, & on other end is 2 short coax cable lengths; & 1 length goes to 2 meters; & the other length goes to 70 CM1) (I have a Kenwwod TS-2000)
That would be a diplexer, not a duplexer.

There *used to be* a very, very good design, easily build and readily repeatable, on that site. It appears that the site owner has had a hissy-fit over criticism of a "magical antenna" design, and has pulled it down. A spot of googling will turn up a copy of the original article, though, which I won't link to directly just in case HB9ABX gets even more upset. Alternatively you could email him and see if he'll sell you a copy.
