Underground Antennas in Russia

 

RN6LIQ

I used the Underground Antenna at the radio- center where I served. However, I do not know nothing about design of the antenna. The antenna works worse compare to usual (placed) on ground antenna. It is a reserved antenna that would be used when the usual stationary antennas were destroyed. However, for survival purposes the radio center and its electro station also should be placed underground….

I constructed one of the Underground Antennas at 1984- 1986 years. It was not so far from Kaluga (Russia). The antennas were placed on a field with several km in (L/W) dimensions. There were installed (in some depth) coaxial cables and copper arrays. Then all were buried and the place was finished to flat surface by bulldozers DT-500 and DT-1000. I do not know for what the frequency band the antenna were designed.

I saw such antenna near Tarusa, Kaluga- region when I served in the Soviet Army. It was Summer – 1987. Soldiers (from unit where I served) for two days did masking of the antenna. It was practically flat filling (near 2 meters height) with size of a football pitch. There were crushed rocks in bitumen and some strange (looks like selicagel) “balls” in the filling Upper the filling there was a grid from thick (near 40- mm in diameter) coaxial cable. We took topsoil from a nearest water meadow and put those one a top of the filling.

When I served in the Soviet Army (it were 1976- 1978 years) I constructed the Underground Antenna near Kozelsk, Kaluga region. It was a grid from a coaxial cable RK-75-24x17. It was very heavy coaxial cable in 60-mm diameter. The antenna was tested from several tens kHz up to 20-MHz.

(Note from I.G.: Russian coaxial cable RK- 75- 24x17 is special steel-clad, water and moldy protected cable that can be installed under the ground.)

At the 80s I was served at a communication unit near Leningrad (today Sankt- Peterburg). There was an Underground Antenna. I remembered that we used to the antenna with radio R-140 for communication with Monchegorsk. (I.G.: Distance between  Leningrad- Monchegorsk is 1200 km.) 

 

Note I.G.: Underground Antennas with fully automatically underground radio- centers were (or are) widely used in the Soviet/Russian military system Dead Hand (also known as Perimeter, Hand from Coffin).
