Chapter 2 

The EN1501-EXT is designed to be easily interfaced with your meter or 
product, however integration must conform to the following:

 A. The EN1501-EXT must only be connected at the four pin header.

 B. All cables and wires must be routed away from the component side of the 

EN1501-EXT.

 C. The on-board antenna must not be tampered with; no connection to an 

alternate antenna is provided.

 D. The meter or product must not include an integrated secondary colocated 

radio module.

 E. The EN1501-EXT on-board antenna should be placed so that it is facing 

away, or otherwise isolated from, your device’s ground plane. 

 F. Components that are sensitive to RF transmission, such as high gain 

circuits, should be isolated from the on-board antenna to prevent 
interference.

 G. EN1501-EXTs should not be mounted on metal surfaces or inside metal 

enclosures. They should also not be mounted where sheet metal ductwork, 
wire mesh screens, etc. might block transmissions.
