Decible Products DB224A Wiring Harness

[TeRayCodA]

After doing some extensive cleaning,and checking out the harness,I have found that I have an "Open" short on the bottom harness on the center conductor.The RF is going straight up the support pipe bypassing the bottom 2 dipoles,and only working on the 2 top dipoles.
Can I just order the "bottom"wiring/coax harness for this antenna,or will I have to order the whole antenna harness as one?
I realize this is a mixture of 35ohm/75ohm coax at 1/4wave multiples.The top half of the antenna is good.Put it up on a 10ft pole,and,it works great.If I could find some 35ohm coax with a velocity factor the same as the DB Products,I could make this harness myself,I have a way of making those weather-protected couplings.just wondering if they sell the "bottom"half.I will make this antenna work one way,or another.

Here's a diagram for the Decibel Products DB224 Harness Assembly from the repeater-builder website.

There's a lot of useful information on the diagrams.

I recall some discussion as to whether Commscope (formerly Decibel Products) will sell a replacement harness. Some have been told no, and others have said yes.......so it probably depends on who you talk with.

If you decide to make your own harness, you will need to find a cable matching both the impedance and velocity factor in order for you to use cable lengths specified in the drawing.

The VB83 cable has a 35 ohm impedance, and the VB11 cable has an impedance of 75 ohms. Both have a 65.9% velocity factor.

Thanks,I saw that page a few weeks ago.

After doing more continuity testing,I found a bad solder joint inside the triangular plastic 'weatherboot'.I took a Stanley knife,whittled away,until I got down to the solder(Not Fun),and,there it was.The center conductor of the VB-83 had separated from the main feed coax.It seems years,and,years of the harness 'swaying' on the support pipe caused the center coax conductor to break free,from the main feedline.(I may add,that when I accquired this antenna,it was NOT taped very well on the bottom half) So,I will go ahead and strip the other weather boot down also,and,repair it too.
