I went up to Waiatarua in West Auckland to have a look at our transmitter today. It's at BCL's transmission site, one of the biggest in the country. I probably got my annual dose of radiation standing near all that gear but it was impressive seeing all those huge transmitters lined up next to each other with massive cooling and cabling systems linking them to the mast.
Our transmitter is a dinky toy compared to those of the networks, but sometimes small and shapely does the job as good as brute force.
Sorry the poor quality of the pictures, they were taken via cellphone.
