Terminator Internal Jumper Settings
The five antenna types supported with the BevFlex-
4X have different impedances that must be matched to 75Ω RG-6
coax. That is the job of the terminator units. Jumpers inside the terminator units select the proper taps on the impedance
matching transformer. Jumpers G1 and G2 must be set for the antenna system type you are building.
The factory default is for Beverage/BOG configurations. You will need to change the jumpers if you are building a Flag,
EWE, or VE3DO antenna. If you are unsure of how the jumpers are set, measure the resistance between one of the
terminator stubs and the outer shell (shield connection) of the F connector with an Ohm meter. A low resistance indicates
it is set for the Beverage/BOG configurations, where the coaxial cable is used as the antenna.
