By the preceding section, it is seen that a dual band blade antenna can be polarity diverse as well as dual band.
2.
Baseline 8 Rivet Joints ( in the 2000s ) introduced the first major change to the external RC-135V / W configuration replacing the MUCELS antennas with plain blade antennas.
3.
Most aircraft featured a swept blade antenna on the upper fuselage, as well as extra wire antennas between the vertical fin and upper fuselage not found on other C-130s.
4.
For economical reasons the aircraft are not modernized, apart from fitting an additional radio RS-6113-2 C2M with a blade antenna on the top, but they receive a new grey multishade camouflage, similar to other Polish aircraft.
5.
Externally distinguished by the'hog nose'radome, the aircraft also featured spinning " fang " receiver antennas below the nose radome, a large blade antenna above the forward fuselage, a single'towel bar'antenna on the spine, teardrop antennas forward of the horizontal stabilizers on each side, and the trapeze-like structure in place of the refueling boom.
6.
One way to create a dual band blade antenna is to create a slot in a blade antenna that is less than or on the order of \ tfrac { \ lambda } { 10 } so that the lower frequency does not'see'the slot ( it is a rule of thumb that the perturbation created by a discontinuity less than \ tfrac { \ lambda } { 10 } on a structure is negligible ).
