Antenna porn. A tribute to the BBC's 648kHz service.

Tribute to BBC 648 kHz Orfordness - The Enthusiast's Version from Jonathan Marks on Vimeo.



The budget cuts to the BBC are obvious on-air even from here. This video is an interview with an engineer at an amazing transmission site that was used for beaming radio into Europe from a salt marsh with very high power at an ex radar site.

Is running co-ax up the mast, with the mast base grounded and the feed point at the top, common?

Nice glimpses of an old Optimod in there too. It's great to see that the engineers salvaged some valves and coupling coils for a display, it won't be long until these beautiful components are very rare.

Here's a big antenna being demolished:



And another.



Thanks to mate Nigel for these.
