For an English speaking audience, I will add what I know of this military measuring device,

"Equivalent Antenna"
This piece can be used to measure AC amperes at power-line frequency or RF as an antenna current meter or dummy load for tuning up a transmitter. The porcelain-insulated terminal marked in Cyrillic "ВХОД  (Vkhod) = INPUT is used for RF current measurement. The back of the device has a grid of holes for ventilation. The top has a leather carrying handle and a stencil-painted number.  The other terminals are  ВЧ  for  высокая частота  (vysokaya chastota) =  (high frequency or HF) and З is for земля  (zemlya) = earth or ground)  The meter itself shows 30-50 Hz and up to 7.5 MHz which I assume is the designed upper limit.  The meter also shows сделано в ссср   (Made in USSR)

What's inside?
The unit is very well constructed with a case made of heavy phenolic. It contains five 50 ohm carbon resistors in parallel resulting in a net resistance of 10 ohms. Each of the five resistors can probably handle about 10-15 watts. The net resisance is in series with the meter thermoccouple.

Russian sources have informed me that the device was mainly used with the R-130-M HF Radio.
