A question for our scalybacks

Have any of you, ever come across water running down the inside of co-axe cable..like from the top of a mast to the equipment...

Not a "Scaly" as you well know Gordon, but I have seen that in two instances.

One was when a mast was being taken down over here, it was in a UDR base, the other was my own TV aerial in my old house, that one caused a "slight" problem with the TV

The bod who came to look at the TV said that the joint at the aerial must have had broken sealing or the outer sheath was damaged.

I had never seen it before this morning when, i was met by a large puddle on my living room floor.As we have been having rather stormy weather my first thought was the roof.Took me a little while to catch on what it was.Will have to use my media center TV untill i venture on to the roof to investigate.

Can't say that I have and that includes time in amateur radio.

There was a friend of mine whose elderly neighbour complained that his equipment was interferring with his tv. Knowing that he complied with all the regulations he offered to look at his tv. The old guys coax had no sheathing on at all and was just bare. He put a new one on for him

After a while the silicone sealant that is used on and around joints becomes, not actually brittle but can sustain cracks causing water to migrate inside the sheathing, this is more prevalent on mast heads or roof top mounts where wind causes the tower or antenna to move in the wind. Like everything else, periodic maintenance is required.

Len (Ciphers) .. and a Liney from waaaaay back

Needless to say there are silicon sealants and silicon sealants!
I used to make my own UHF antenna and tried several polymer clear adhesives to seal the terminal housings before I found one that withstood the harsh Australian climate. It was one that they use in fish tanks. Does not crack,shrink etc.,

Once the seal does break of course water will run down inside and out!

LOL.

I took my life in my hands,and ventured onto the roof to-day.The problem looks to be birds pecking the aeriel cap (like they did with milk bottle tops,)exposing the cable.Replaced the lot and all is fine..Apart from my nerves....lol

Len ??You intrigue me...Why give up the cushy life of a cipher op with its nice warm waggons and almost virtual anonimity for the hardships of a liney out in all weathers and conditions???????..

I'm not too bright ... I come from Hampshire ... actually in just about all of my yearly assessments the message came through loud and clear ' this man is wasted in brigade Signals he should be put to better use' ... volunteered for Federation of Malay Military Forces but was turned down as too young .. took every weapons and drill course I could wangle on to .. GSO II (Ciphers) MELF even suggested that I should be in the infantry ... just shows what a shitty cipher op I was .. I loathed the trade .. hence the change to a Hairy Ass ...
