    eHam TBJ-1 Review [EXCERPT]
    http://www.eham.net/reviews/detail/13520I saw Ed Fong’s TBJ-1 triband antenna in the March 2017 QST issue. It is 6ft long and it is enclosed in ¾ inch 200 psi pvc pipe. Two connector types are available, SO-239 or N type. I chose the SO-239 connector for my version.

    As well as a tri-band base antenna, it is also my preferred antenna for portable and EmComm. With help of a launcher to get the initial nylon cord over a branch, the TBJ-1 makes the ideal Field Day antenna. With no radials involved, hoisting the antenna into place as well as de-installation is a breeze.
    SWR was less than 1.4:1 on all 3 bands. Performance wise, I’d put it up against any 6’ vertical or J-Pole on the market.
