Foxhunting Attenuators

Foxhunting attenuators can be used to help find a nearby hidden transmitter in the last few hundred feet when a radio's s-meter is maxed out. They have a male and female SMA connection so they can be easily inserted between a radio and an antenna. Avoid transmitting when these attenuators are connected to a radio.

AA1 Active Attenuator

The AA1 is an active / offset attenuator that creates an image of a transmitter on a new frequency. The signal strength of this image can be adjusted to bring it to a useable level. This design is based on the K0OV attenuator.
