The MONO-A0099 is an HF whip designed for monitoring applications in the 9 kHz - 200 MHz frequency band. The whip is loaded along its length to control the elevation pattern of the antenna for optimal gain performance on the horizon. The whip is detachable for storage and transport and has a spring to ensure it can survive in harsh operating environments. The MONO-A0099 antenna is well suited for the DF-A0029 and DFA0095 antennas, where it is utilised to improve monitoring sensitivity. Every DF-A0029 and DF-A0095 is already fitted with the necessary internal cables and connectors; this whip antenna is simply connected and bolted on in place of the lifting eye plate
