7.2.4 External Filter

Although the Phantom II is capable of filtering-out RF noise in most
environments, there are circumstances that require external filtering.
Paging towers and cellular base stations in close proximity to the
Phantom II antenna can desensitize the receiver. CalAmp's external
cavity filter eliminates this problem.
