The Lakihegy Tower is a 314 metre (1,031 ft) high radio mast at Szigetszentmikl├│smarker-Lakihegy. The Blaw-Knox type tower was built in 1933 and was one of Europe's tallest structures at the time of construction. It was designed to provide broadcast coverage for Hungarymarker with a 120 kW transmitter.

Developed in the U.S.A.marker, the cigar shaped mast was specially designed to radiate radio waves in such a way that reduce fading. Thus it was able to serve the whole country.

The mast was destroyed by retreating Germanmarker troops in World War II, but was later rebuilt in 1946. In 1968 the tower was upgraded to serve the new 300 kW transmitter (amongst others, the ceramic base insulator had to be replaced to withstand the higher voltages).

In 1977 the new 2MW transmitter at Soltmarker has replaced the Lakihegy tower as the primary national transmitter. Subsequently, it was nearly torn down in 1981, but widespread objections saved the tower, and later it became a protected industrial monument.

This guyed mast, which is probably still the tallest structure in Hungarymarker, is currently being used for power-distribution control data transmission at 135.6 kHz with a power of 100 kW; the data bursts are at 200 baud with +/- 170 Hz FSK (Frequency Shift Keying).

In Europe there are similar radio masts at Lisnagarveymarker, Northern Irelandmarker, at Rigamarker, Latviamarker, at Vakarelmarker, Bulgaria and at Stara Zagaramarker, Bulgaria.

There are two smaller guyed mast radiators for mediumwave at Lakihegy. They are as Lakihegy Tower insulated against ground, but smaller and from conventional construction type.

The mediumwave frequency of 540 kHz with 150 kW was diplexed (diplex) to the Lakihegy Tower in 2006 by Bernd Waniewski.
