Looks really tall!
You can visit in the internet other facilities used for transmitting orders to submarines like Torreta de Guardamar:
- DHO38 in Saterland, Germany, 8 masts each 352.8 metres tall (
http://de.wikipedia.org/wiki/DHO38 )
- NSS Annapolis in USA, multiple masts, tallest 365.8 metres (
http://hawkins.pair.com/nss.shtml )
When you look at the basements of the towers, you see that they stand on large insulators. In fact the towers show, when transmitter run, voltages of 100 kV to 300 kV against ground, this is the voltage of a large high voltage powerline!
I suppose Torreta de Guardamar stands also on large insulators. Its guys may be also connected with insulators to the mast structure and/or divided by huge insulators.
The reason of the enormous height of Torreta de Guardamar is simple: it is an antenna for very long waves. In order to work well, it had to be very tall ( in fact, it should be much taller, but this would bring technical problems and by using special measures like feeding the mast over a huge coil and using the guys as part of the antenna system, this is not necessary. One can built facilities for this purposes with lower masts, but then you have to use multiple of them. In Grimeton, Sweden, there is such a facility, look on
http://en.wikipedia.org/wiki/Grimeton_VLF_transmitter . A further possibility is the usage of an antenna spun across a valley )
If possible, please post some pictures made at daytime from Torreta de Guardamar, its basement and its guys.
