General Description The TACO Model D4000 and D5000 series antennas are vertically polarized omnidirectional antennas, specifically designed to provide optimum performance throughout the DOT/FAA frequency band ranging 118-136 MHz and 225-400 MHz. The internal elements or dipoles are enclosed in a fiberglass radome, ultimately resulting in a lightweight, low profile, rugged communications antenna.
