[2] On Monday 23 September 1957 a 110 foot experimental aluminium mast was erected to test strength of transmissions around the area, with BBC engineer Colin White of the Field Strength Test Unit.

[4] On Monday 14 October 1957 a war-surplus barrage balloon was flown at 600 ft. Morborne itself was 184 ft high.

Rowridge, North Hessary Tor and Pontop Pike are a similar design, but built two years earlier.

The 560 ft lattice mast would open on Monday 5 October 1959, with 405 line television.

[17] A 154-metre (505 ft) guyed high-steel lattice mast, belonging to Arqiva, is used primarily for FM broadcasting but carries many other services.

In June 1961 the original GPO 328 foot steel lattice tower had reached 100 feet, which weighed 80 tons.

[21][22] The 1961 lattice GPO tower was replaced in September 1970 by a 280 ft concrete tower, built by Monk of Warrington, as more communication dishes were needed, with 9,000 more trunk circuits being needed.

It is used mainly for point-to-point microwave links and forms part of BT's national telecommunications network.
