The Solarcon Antron A-99 is a fibreglass omnidirectional base station antenna for CB, 10m amateur, and export use — delivering 9.9 dBi gain from a half-wave over quarter-wave design where the entire antenna radiates, not just the tip. Rated at 2000W PEP and standing 18ft tall, it's one of the most popular high-gain CB base antennas available. The Twin Ring Adjust-A-Match tuning system allows the input to be optimised for SWR across a range of frequencies: raising the rings raises the frequency, lowering them lowers it — giving you precise control without additional equipment. Each antenna is individually tested and provides lightning protection up to 14,500 volts. Comes in three sections for straightforward assembly. Add the Solarcon GPK-1 A-99 Ground Plane Kit to lower the angle of radiation and improve range further.
