Antenna info needed

I came across a good 2 meter 12 element beam. The boom is aprox 19 ft
long. It has 4 driven elements in a "log" or lattice configuration. I
need info to make the coax connection. Does anyone have an Idea as to
Mfg? The driven elements are spaced about 7 inches apart. It is in
good shape except for the missing connection points.
Thanks, 73's

I would connect a feedline to the mounting screws of the front most DE and
measure the SWR. If you get anything like 4:1 it is 200 Ohms. The KLM 6m
beam with 2 driven elements requires a 4:1 balun. I have not seen the KLM
2m.
According to an old AES catalog, 2m KLM antennas in this range had boom
lengths of 15.33, 21.5, 12.9, 28 , and a circularly polarized 22 element on
a 19 foot boom; nothing with 12 elements, but it could be older.
