Editing Mendip transmitting station (section)

== Description ==
The station is owned and operated by [[Arqiva]] (which acquired National Grid Wireless, previously Crown Castle).

Until 2008 a [[Glass-reinforced plastic|GRP]] aerial cylinder, containing the analogue television transmitting [[Antenna (radio)|antennas]], was mounted at the top of the mast, bringing the total height of the structure to {{convert|305|m|ft|0}}. With a mean height of {{convert|596|m|ft|0}} above sea level, these antennas were among the highest in the UK. They were removed in 2010, the antenna cylinder being replaced with a new antenna assembly, ready for [[Digital terrestrial television in the United Kingdom#Digital switchover|digital switchover]] later that year. The present assembly is slightly shorter than the previous cylinder, causing the overall mast height to be reduced from {{convert|305|m|ft|0}} to {{convert|293|m|ft|0}}.<ref>{{cite web|title=Mendip|url=https://www.thebigtower.com/live/Mendip/Index.htm|website=The Big Tower|access-date=6 April 2018}}</ref><ref>{{cite web |title=Mendip |url=https://tx.mb21.co.uk/gallery/gallerypage.php?txid=620 |website=mb21 |access-date=26 March 2024}}</ref>

There are red [[aircraft warning lamps]] (six sets of two lights) on the mast, and two lights on top. The mast can be seen from as far away as [[Puriton]] during the day, and the aircraft warning lights make it visible at night from most of the [[Somerset Levels]] and from areas of South Wales, such as the high ground near the [[Wenvoe transmitting station]].{{Citation needed|date=November 2024}}
