OPERATING INSTRUCTIONS

ASSEMBLY INSTRUCTIONS

To prepare the antenna for operation, attach the shielded loop antenna 
element to the top of the impedance matching/amplifier base. 

 

SETUP INSTRUCTIONS

The antenna can be mounted to any tripod with a 1/4-20 attaching stud. 
Connect the output BNC connector on the side of the antenna to the input of a
