MIL-DTL-23806B
4.5.11 Outer conductor flaring. The cable shall be subjected to the flaring of the outer conductor to the
diameter as specified below. The cable specimen length and maximum flare diameter are as follows:
Approximate length (inch)
Flare OD (max.)
Cable size (inch)
.5
24
.700
.875
36
.960
4.5.11.1 Flaring procedure. Cut one end of the sample square with a tubing cutter. Carefully remove
.125 inch of dielectric between inner and outer conductor using a flaring device or standard plumbers tube
flaring tool; flare the prepared end of the outer conductor not exceeding the maximum diameter as
specified in 4.5.11.
5. PACKAGING
5.1 Packaging requirements. For acquisition purposes, the packaging requirements shall be as
specified in the contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-
house contractor personnel, these personnel need to contact the responsible packaging activity to
ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control
Point's packaging activities within the Military Service or Defense Agency, or within the military service's
system commands. Packaging data retrieval is available from the managing Military Department's or
Defense Agency's automated packaging files, CD-ROM products, or by contacting the responsible
packaging activity.
6. NOTES
(This section contains information of a general or explanatory nature that may be helpful, but is not
mandatory.)
6.1 Intended use. Cables covered by this specification are intended for use in Shipboard Radio
Frequency communications equipment.
6.1.1 General information regarding foam dielectric cable. Foam dielectric cables are noted for their low
loss characteristics. Attenuation loss in a foam dielectric cable are as follows:
a. Normally is not quite as low as that in air dielectric cable especially at higher frequencies
(specified in MIL-DTL-22931 and MIL-DTL-3890).
b. Is approximately 15 percent lower than the attenuation of a solid polyethylene dielectric of a
corresponding size (specified in MIL-DTL-17).
c. The average power rating of foam dielectric cables (as limited by temperature rise) is between
solid polyethylene (which has a lower power rating) and air dielectric (which has a higher power rating) for
corresponding cable sizes. Even though foam dielectric cables have a greater attenuation loss than
corresponding air dielectric cables, the foam cable has one major advantage in that it does not have to be
pressurized with dry air or nitrogen.
6.1.2 Type I. Type I cable is unjacketed, and is therefore approximately 10 to 15 percent more
economical than the jacketed version. Type I is not recommended for use in a corrosive atmosphere such
as on shipboard.
