I have often found situations where a piece of gorse is touching a fence, a crook insulator is arcing over, or the earth connection is inadequate - all causing a lot of interference to sensitive communications equipment. All too often, farmers have the "She'll be right mate" attitude to electrical things - and fences are no exception. In other words, as long as it's keeping the stock in, there isn't a problem. You effectively have a VERY big long-wire antenna - into which you are dumping a large amount of energy every few seconds. A better spark-gap transmitter there never was! I have a friend up north who recently had broadband installed. Somewhere, within a 5km radius of his house, is a farm with a crook fence issue. The clicking in the phone is distinctly audible - but Telecom's response is "We will send you out a pamphlet which tells you how to deal with the issue - but we won't do anything to help". So, it's up to the consumer to go around all the neighbouring farms and find out whose fence is causing the problem, where it is, and ask the owner to rectify the situation. I am sure that if a shorting fence was interfering with Telecom's own equipment they'd be out there lickity-split and have it dealt to. I can understand it causing problems with the Wi-Fi. Before my friend was on broadband, he had dial-up - and invariably it just refused to connect to the line card at the exchange. Listening to the line, it would simply keep trying to associate, and eventually give up. On the rare occasions when the fence was turned off and the line was noise-free, the dial-up worked just fine. The solution here, as others have already indicated, is to fix the fence system up. You need a "Megger" - which can look at the resistance of the fence line to ground - it should be in the millions of ohms (disconnect from the fence unit first!) If it is low, then you need to walk the miles of fence you have and megger from different points to try to isolate the faulty section. |
