BevFlex-4X Installation Manual Rev 2.23 November 2019
Feed Unit DC resistance measurements:
The resistance measured with an Ohmmeter from the
center pins of all four of the “F” connectors to their
respective outer shields should measure less than 1 Ohm showing that all the transformer windings are intact.
The resistance measured with an Ohmmeter from the antenna forward “F” connector threads to the antenna
reverse “F” connector threads should measure less than 1 Ohm.
The resistance measured with an Ohmmeter from either the antenna forward “F” connector or the antenna
reverse “F” connector should measure as an open circuit to shield of either the A or B feedline “F” connectors.
Switch Unit DC resistance measurements:
Here are some simple tests with an Ohmmeter to check the functionality of the Switch Unit.
If a transmitter or transceiver accidentally feeds RF power into the Rx port of the control box, a micro-fuse will
open to protect the BevFlex-4X receiving antenna components. You can easily check the condition of this fuse
by measuring the resistance from the center pin of the Rx connector to shield ground. The resistance should
measure approximately 8 Ohms. If this port measures open, the fuse has blown. With the direction switch in the
“Forward” position, the resistance reading from the center pin of the A port to shield should be approximately 75
Ohms. With the direction switch in the
“Forward” position, the resistance reading from the center pin of the B port
to shield should be approximately 1 Ohm. This is the resistance of the transformer winding.
With the direction switch in the “Reverse” position, the resistance reading from the center pin of the B port to
shield
should be approximately 75 Ohms. With the direction switch in the “Reverse” position, the resistance
reading from the center pin of the A port to shield should be approximately 1 Ohm. This is the resistance of the
transformer winding.
