Racal Antennas Limited has many years of experience in design, development and manufacture of manpack/portable antennas for the military user. They have been developed after consultation with military users and radio manufacturers worldwide.
The 4020-910 ground spike antenna kit is for use with manpack radios and gives the capability to remote an antenna from its radio allowing the soldier to operate from a more secure environment, which could either be a shell scrape, tent, building, or any other protective environment. The antenna can also be elevated onto buildings and trees or used in conjunction with a 5.4m mast kit (model 4025). When the antenna is elevated with the 5.4m mast kit operating range of the radio is significantly improved.
The specifications in this section apply when the Ground Spike Antenna is mounted in the ground mounted role or when mounted in the 5.4 Metre manpack mast
