Haverfordwest transmitting station
|Mast height||154.4 metres (507 ft)|

|ITV region||ITV Wales|
The Haverfordwest transmitting station is a broadcasting and telecommunications facility located at Woodstock about 13 km (8 mi) to the north east of the town of Haverfordwest, in Pembrokeshire, Wales (grid reference ). It was originally built by the BBC, entering service in early 1964 acting as a main transmitter for the 405-line VHF television system, and as a repeater for Band 2 VHF FM radio received off-air from Blaenplwyf transmitting station. It is now owned and operated by Arqiva.
The site has a 155 m (509 ft) guyed steel lattice mast erected on land that is itself about 187 m (614 ft) above sea level. The radio broadcasts cover the majority of Pembrokeshire, except the north eastern part of the county.
When UHF analogue television was added in 1990, those services were provided only at very low power and only designed to cover the small villages of Puncheston, Castlebythe, Little Newcastle and Rosebush, which are all located within about 7 km (4 mi) of the mast.
It currently carries three digital television multiplexes at twice the ERP of the analogue services that they replaced, thus providing digital TV to a much larger area than had been served before.

The 405-line VHF television system closed down permanently across the UK, and from then until Summer 1990, the site transmitted no television signals, just VHF radio.

Colour TV was added very late: Haverfordwest became a UHF relay of Preseli. Being in Wales, this transmitter radiated the S4C variant of Channel 4.

All the remaining analogue TV services closed and were replaced with the standard three multiplexes of Freeview Lite. Notice that unusually, the digital TV services are broadcast at twice the ERP that had been provided in the analogue TV days. At most sites, the digital services are broadcast at a fifth the ERP of the old analogue channels.

As a side-effect of frequency-changes elsewhere in the region to do with clearance of the 800 MHz band for 4G mobile phone use, Haverfordwest's "BBC B" multiplex was moved from channel 48 to channel 47. Additionally, all the transmissions at the site gained a +3 dB power boost.
