Monster coil inductance for pa ham radio
For the powerful amplifier (~10 - 15 KWATT)
Coil will consist of two identical section.
Each section will consist also of two parts.
1 part (external) a constant from 6.5 turns.
2 part (internal) a constant from 6.5 turns.
The design allows to switch coils in any sequence.
It is possible to apply this coil in the amplifier of capacity or the device of adjustment of the aerial to any ranges HAM radio (also 1.8 mHz).
Number of coils 6.5 turns constante (external) + 6.5 turns constante (internal).
Diameter of winding (external) 210 mm
Diameter of winding (internal) 190 mm
The silvered copper tube in diameter of 6 mm.
The second section is identical.
Length (max.) ~ 500 mm (~12.6inc)
Diametr (max.) ~ 260 mm (~6.55inc)
Cylindrical coil for the high-stability powerful amplifier. It has the teflon (between coils ) + ceramic (longitudinal cores in diameter of 20 mm) basis. The device has very exact and stable parameters. Due to such reliability such coils are applied in military radio equipment.
As a result of long storage the copper strip has darkened a little.
However it does not influence working qualities of the coil.
