| 492519 | 2006-10-19 00:21:00 | Well the title says it all About 6 months ago, after deteriorating picture quality I replaced my connection box (on the roof) (the one that combines the VHF and UHF aerials), I have recently noticed picture quality on prime and maori tv decreasing, so i checked the connection box on the roof and the uhf connection is pretty badly corroded all other connections are fine The uhf cable from the aerial to the connection box loops down to the connection box (same as for the VHF cable) to stop water getting into the connection box infact everything is set up pretty much the same, Any ideas what could be causing this? it is only the UHF connection that is effected, not the VHF (that is still in perfect nick) |

I do and I have no deterioration of over-air antennas or splitters after almost 5 years now. It might be the 240 volt thing again too. :blush: |

The plating on the connectors is probably dodgy enough for 40 kM inland, but your horizontal rain straight off the sea would not help at all. I would suspect that the connector batch was different for the UHF one, and more susceptible. replace, reconnect or clean up and reconnect and apply some anti-corrosive product (grease, as above). |

| 492522 | 2006-10-19 01:29:00 | Anyone know where (in NZ) to get "dielectric grease"? About once a year I go up on the roof and spray aerial connections with:D WD-40. |

You know how much I love WD-40, but this isn't the correct application for it . Dielectric grease can be purchased at most auto parts stores . . if you have such a thing in Upsidedownland . :waughh: It is the same lubricant that is used to make sparkplug boots not stick to the sparkplug when you go to remove them next time . Comes in a tube (or as in the US) in a small package like mustard and other single-use condiments for fast foods (if you have such things in Upsidedownland) . :waughh: Do not however try to use mustard or mayonnaise as dielectric grease . . . it won't work, and I know of what I am speaking here . |

| 492525 | 2006-10-19 02:19:00 | Get an indoor splitter. I have one. Trevor :) Yes but for that i would have to rewire both aerials as the cables wouldn't reach indoors Dielectric grease does sound the way to go, just suprised that one connection was so corroded and the others were fine cheers |

| 492526 | 2006-10-19 07:26:00 | got a pic? depending on where its corroded it can be perfectly fine . i've had it many a time where corroded connections where in fact connection perfectly . what tends to happen is corrision forms over the connection which basicly seals out and water getting into the actuall contact patch . the other thing is you may be getting water in the cable up at the aerial which will suck through to the connection box . i've rewired brand new homes because of this (idiot sparkys leaving the cables out in the weather) . |
