Abstract
Abstract A method is disclosed for terminating semirigid coaxial cable that is phase matched which is accomplished by cutting a length of coaxial cable to the exact or approximate desired electrical length. A coaxial connector is permanently terminated onto one end of the cable and a phase-matching test connector is positioned onto the other end of the cable. The cable is tested to determine if the electrical length of the cable is correct. If it is, the test connector is removed and another coaxial connector is permanently terminated onto the other end of the cable. If the electrical length of the cable is too long, the test connector is removed, the cable is trimmed to the correct length, the test connector is reapplied onto the cable, the cable is retested, and if now correct, the other coaxial connector is permanently terminated onto the cable.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
177 words
A method for terminating a length of coaxial cable to a selected electrical length comprising the steps of: cutting the coaxial cable to the selected electrical length; permanently terminating one end of the coaxial cable with a coaxial connector; positioning a phase-matching test connector onto the other end of the coaxial cable; measuring the phase angle of the coaxial cable to determine the electrical length of the coaxial cable; removing the test connector from the coaxial cable, and if the electrical length of the coaxial cable is correct, permanently terminating the other end of the coaxial cable with another coaxial connector; or, if the electrical length is not correct, removing the test connector from the coaxial cable, trimming the other end of the coaxial cable to the correct electrical length, positioning the test connector onto the trimmed end, measuring the phase angle of the trimmed coaxial cable to make certain the electrical length is correct, removing the test connector from the coaxial cable, and permanently terminating the other end of the coaxial cable with another coaxial connector.
Claim 2
Independent Claim
177 words
A method for terminating a length of coaxial cable to a selected electrical length comprising the steps of: cutting the coaxial cable to the selected electrical length; permanently terminating one end of the coaxial cable with a coaxial connector; positioning a phase-matching test connector onto the other end of the coaxial cable; measuring the phase angle of the coaxial cable to determine the electrical length of the coaxial cable; removing the test connector from the coaxial cable, and if the electrical length of the coaxial cable is correct, permanently terminating the other end of the coaxial cable with another coaxial connector; or, if the electrical length is not correct, removing the test connector from the coaxial cable, trimming the other end of the coaxial cable to the correct electrical length, positioning the test connector onto the trimmed end, measuring the phase angle of the trimmed coaxial cable to make certain the electrical length is correct, removing the test connector from the coaxial cable, and permanently terminating the other end of the coaxial cable with another coaxial connector.
Claim 3
Dependent Claim
27 words
a method as set forth in claim 1 comprising the further step of measuring the permanently terminated cable to make certain that the electrical length is correct.
Claim 4
Dependent Claim
84 words
A length of terminated coaxial cable having a predetermined electrical length, comprising: coaxial connector means permanently terminated onto one end of the coaxial cable; phase-matching test coaxial connector means removably fitted onto the other end of the coaxial cable enabling the cable to be measured to determine the electrical length thereof; and other coaxial connector means permanently terminated onto the other end of the coaxial cable in place of said phase-matching test coaxial connector means if the electrical length of the cable is correct.
Claim 5
Dependent Claim
84 words
A length of terminated coaxial cable having a predetermined electrical length, comprising: coaxial connector means permanently terminated onto one end of the coaxial cable; phase-matching test coaxial connector means removably fitted onto the other end of the coaxial cable enabling the cable to be measured to determine the electrical length thereof; and other coaxial connector means permanently terminated onto the other end of the coaxial cable in place of said phase-matching test coaxial connector means if the electrical length of the cable is correct.
Claim 6
Dependent Claim
36 words
A length of terminated coaxial cable as set forth in claim 3 wherein said other end of said coaxial cable is trimmed to the correct length whereafter said other coaxial connector means is permanently terminated thereon.
