[Hi-zreceivingarraydiscussions] Cut/nick on feed line

[dan edwards]

i can second that also....my fault had turned the aluminum braid and tape to virtual dust....had to trim back a ways, toward the shack, to find good stuff; then splice with a fresh pair of F males and and f barrel, and some leftover feedline from the original roll back out to the element...
and mine is shallow buried...6" + / -, too !!...pulling that stuff up was NOT fun...

Hello Ray,
  Well I think you better plan on replacing that cable run. I think the
damage was done electrically when the aluminum was exposed to the air for
whatever length of time. Aluminum oxidizes very quickly in open air. You may
not have trouble now but my opinion is you will later just when you need the
array.
  Remember Ray, that the cables connecting the elements were supposed to be
all from the same roll and the same length. If you don't still have some of
that same roll, my best advice would be to change all four cables which will
insure the best performance. Or you can electrically measure the length of
the cables to match them to a single new one if you have suitable equipment.

Hello Lee & All,

I just noticed a cut in one of my Hi-z 4 sq feed lines. It is about 1 1/2
inch long, the outer shield is cut for about 1 in. The inner aluminum shield
was not cut. Think I must have done this awhile back using my rider mover.

Anyway, I laid the shield back in place the best I could, but about 1/2 in
is missing. I then coated the cut with RTV, let it dry, then covered with 2
layers of Scotch 66 tape. After that, I coated the tape with plumbers liquid
tape.

All seems OK, the voltage is 4.93v on that vertical. The voltages range from
4.93 to 4.98v, not enough to be concerned, I wouldn't think.

Any thoughts on this repair? Can't imagine that it would make any
difference... Let me know what you think.

73 & tnx,

Ray,
