[Repeater-Builder] 4 bay folded j pole questions

[chuckmf1135]

 I received a 4 bay (folded j pole or dipole) it has 34" folded elements
and total boom length around 20'. I wangt to use this for amateur radio
use, however no one knows what freq their business was on.
 I havent seen a setup like this before, two folded elements feed 
w/coax - 50 ohm i guess to a tee then the two tees feed one tee which
feeds a single coax w/ N male connector, are the individual elements
50 ohm?
