Cable Passage - The radome base is designed with a bottom center cable passage and Roxtec® Multidiameter®
blocks for cable strain relief. Bottom center cable passage is recommended, however, a strain relief kit is provided
with the system if off-center cable entry is required. Note:
Strain relief installation procedure MUST be followed to
assure that the cored holes are properly sealed to prevent moisture absorption and de-lamination of the radome base.
Maintenance – The radome must be kept clean and free of residues that will increase the RF attenuation.
Repair - NOTE: Damage to the seal of the inside, or outside, of the radome can allow moisture to be absorbed.
This will result in de-lamination of the radome, increased weight and higher attenuation.
To maintain the RF transparency characteristics of the radome top, any cracks, scratches or other damage to the
surface seal of the tuned radome top must be repaired and re-sealed by a competent “A” layered laminate, or
cored deck, repair professional.
Cracks in, or other damage to, the radome base can be repaired using typical fiberglass repair techniques and
proper sealing of the inside and outside surfaces. Edges of holes in the radome base must be properly sealed to
prevent moisture from being absorbed into the layered construction of the radome base.
Disposal - Should it ever become necessary to dispose of the radome, it must be disposed of using the same
handling procedures as other fiberglass materials.
