The COL23E is a high gain omnidirectional collinear antenna suitable for simplex, duplex or multiple transmit/receive applications. The combination of 6dBd gain and a nominal 2° of negative beamtilt results in a vertical radiation pattern that is ideal for almost all coverage requirements, both local and wide area.

The COL23E is a series fed collinear design which is custom tuned to user specified frequencies. The radiating elements are constructed using ROHS compliant Ecofilm plated aluminium, enclosed in a tapered ruggedised fibreglass radome, which is fitted to an Ecofilm plated aluminium mounting tube. The mounting tube is fitted with three radials to aid in decoupling and enhance pattern control.

The antenna is internally DC grounded aiding in lightning protection and the reduction of static noise. Drainage vents at the base allow the antenna to "breathe," and thus prevent condensation build up.
