One other advantage we saw with the wok is that a deep dish is not as prone to side and rear noise as a conventional sat dish.
The article appeared in our local paper purely as a local item describing over several weeks how each team member had contributed to getting "45South TV" on air. The purpose of the article was not intended to portray that the contruction was anything special. There are many other ways that this could have been achieved. The "45South TV" gets no funding so the tv transmitter was funded by running raffles and everthing else has been funded by several individual digging deep into there own pockets to supply everything else. We are now on air 24hours a day with a loop of local items stored on computer playing to the comunity continuosly, we are also doing a 1 hour local current affairs program 5 nights a week.
The work is pressed steel so it is easy to solder/weld to. The feed cable was kept to less than 1 metre in most versions and is rg219 coax. A 4inch or so, tight fitting piece of thinwall brass tube was placed over the coax and soldered to the wok. The wok feed is a "circular biquad" which is documented elsewhere on the web. The distance from the back of the wok to the feed was determined by measuring the signal recieved at the other end of the link. This shows when the transmit swr is better and is more important than messuring the dish's recieve signal. The wifi units are linksys wrt54g's running ddwrt firmware and the computers are running linux and vlc for video streaming.
