Inspect the board for any bad solder joints, shorts or other problems and correct before use.   Confirm for proper 

orientation of parts.

Install the telescoping antenna using the supplied nut in the location market “ANT”. Tighten the nut gently to 

secure the antenna in place.

Install a 9V battery and press the power switch.  The led should light.  If not, recheck solder joints and component 

placement.  

Usage

 Use a bnc adapter or cable to attach the active antenna to a receiver.  If attaching to a transceiver, use care not to 

transmit into the active antenna as doing so will likely cause damage.

Turn on your receiver and tune to the band of interest.  Press the power switch on the active antenna and you 

should hear a significant increase in background noise and possibly signals.

Tune the receiver and you should hear signals as you would with any other antenna.  

While a short antenna is a compromise, an active antenna such as this can often equal performance of a wire 

antenna.

Performance of  the active antenna can be improved by adding a short 3-5ft section of wire to the telescoping 

antenna.   Just use a clip lead to attach the wire to the end of the telescoping antenna to extend its length.

Always turn off the power switch when not in use to avoid draining the battery. 

Packaging

Packaging is left up to the builder.  The kit can be used as is, built into another assembly or installed in a 

case.

Thank you for purchasing our Active Antenna kit!
