The bucket for the delta loop

Dear Reader,

Today the weather was warm so I was able to raise my delta loop, sadly in very cold weather the fibreglass tubes get stuck together by ice but today early in the morning the temperature was slightly above zero. So I had a go at using the aerial.

I spoke today to a man in Ukrane, A French man, a German, a man in Portugal and some people in Italy. So it was an OK way to spend a hour in the basement.

The fibreglass tubes went up with great ease but I had a problem. To stop the wires getting stuck in the snow I had put them all in a plastic bucket when I put the aerial away at the start of the cold snap. I found today that a big lump of ice had formed and glued all the wires together. So I had to chip the wires out of the ice block.

Now when I went to put the aerial away today I drilled four holes in the bottom of the bucket to stop water and ice building up in the bucket. Sadly I found during the drilling that the bucket shattered, I think it was below its glass temperature. I think that the bucket was polypropylene. If it was isotactic then the glass temperature is about zero degrees centigrade. Before I started to work on the bucket it had been sitting on a pile of snow. Next time I will drill the bucket while it is still warm in the basement before it goes to the garden.


Go on, Have your say !
