The CI 268-60 uses the same radome as Comant's multi-function ComDat antennnas. After adding a ComDat combination antenna, many owners like to match the look for their other VHF antenna. This is the answer. Whats more, the CI 268-60 shares the same footprint and offset connector location as the popular CI 238 which is no longer in production. The CI 268-60 features the same super-tough nickel plated aluminum base plate with integral Nitrile O ring for pressurized applications. The CI 268-60 features a built-in notch filter allowing installation in close proximity to GPS antennas without co-sight interference.
