The Rubber Duckie antennas are omni-directional with 360 degree transmission pattern around the antenna. These antennas are available by frequency range and signal gain measured in dB. RaceAmerica uses 900MHz and 2.4GHz frequency antennas.
Any antenna will work as long as the frequency matches the transmitter. The better ones have a higher signal gain and provide excellent performance at greater distances than standard antennas. Usually the standard Rubber Duckie antennas are 2.1dB gain while the higher performance antennas RaceAmerica sells are 3.9dB to 5.2dB gain. The higher performance antennas are slightly taller but, other than that, look identical.
To maintain the range and performance you have with the antennas supplied with the equipment, purchase the higher gain models as replacements. RaceAmerica part numbers are 45-0675 for 900MHz and 45-0525 for 2.4GHz available from our online store.
