The Longshot External antenna is designed to allow shooters to have peace of mind that their camera will not be shot. With the external antenna, you have the ability to protect your camera with a piece of steel plate or place it behind a berm and to place the antenna far out of the line of fire to relay the signal. The external antenna is completely self contained, wireless, and can be placed up to 75 yards away from your primary camera. External antennas are custom programmed to match your primary camera system and can only be ordered directly from our website, longshotcameras.com. Connection is the same as the LR-3.
