MAINTENANCE 

 

To ensure reliable and repeatable long-term performance, annual re-
calibration of your active monopole preamplifier by A.H. Systems’ 
experienced technicians is recommended. Our staff can recalibrate almost 
any type or brand of antenna. For more information about our calibration 
services or to place an order for antenna calibration, visit our website at 
www.AHSystems.com or call (818) 998-0223.

 

 

CLEANING

 

 

Turn off and unplug the unit before cleaning. 
 

1. 

The outside of the Active monopole antenna can be cleaned with a soft, 
damp cloth.

 

2. 

The ground plane can be removed and washed in warm soapy water 
(not dishwasher safe). Do not use abrasive cleaners as they may 
damage the surface. Dry before replacing in the unit.

 

3. 

The BNC connectors can be cleaned of dust with a small soft brush.

 

 

REPLACING THE BATTERY ASSEMBLY

 

 

Turn off and unplug the unit before changing the battery pack assembly. 
 

1. 

Remove the four 6-32 flat head screws from the bottom of the ground 
plane. 

2. 

Disconnect the battery lead from the PC card. 

3. 

Re-connect the lead from the new battery pack to the PC card. 

4. 

Snug the four 6-32 flat head screws. 

5. 

Ensure that the orientation of the amplifier box is that the input rod 
connector is facing toward the center of the ground plane. 

 
Safety: Please dispose of batteries responsibly; never dispose of batteries in a fire, 
batteries may explode or leak. 

 

Never dispose of used batteries or rechargeable batteries in 
household waste. As consumers, users are legally required to 
take used batteries to appropriate collection sites, the retail store 
where the batteries were purchased, or wherever batteries are 
sold. 

 
Disposal

: Do not dispose of this instrument in common waste. 

The user is obligated to take end-of-life devices to a designated 
collection point for the disposal of electrical and electronic 
equipment.
