Overview
This sleek new design was developed for Cessna's 182 and 182T aircraft. Impressive with its low-drag and good looks, the CI 248-5 has been credited with adding 2 to 3 Knots on certain aircraft. The first totally new look in VHF antennas in decades, the CI 248-5 was tested to some of the most rigorous requirements outlined in RCTA DO-160D. Rated to 350 Knots for most high powered twins, the antenna is also certified for helicopter applications.
Truly unique, the CI 248-5 is the only VHF antenna with a built-in notch filter, this allows the CI248-5 to be placed in close proximity to GPS antennas without interference issues.
