In a radio station, power is generated by a transmitter, usually housed comfortably in a shack, and the RF power is led to the (usually) remote antenna by a cable, or transmission line, which in short wave stations can be several wavelengths long. An antenna tuner is generally placed at the antenna end of the transmission line. Audio power amplifiers are rated as to how many watts they can put out. For example, an amplifier that is used in a home stereo may have a rating of 100 watts per channel. The mathematical equation for power is as follows: P=VI = I 2 R=V 2 /R If the reflected power is zero there will be no standing wave on the line and no excess stresses on it. If the reflected power is zero the generator can deliver its maximum rated power into the load. The difference between the forward and reflected powers is the real power delivered to the load, but:

LMR Coaxial Cable Power Ratings Maximum Power Rating – Kilowatts(KW) at MHz. LMR Peak RF Power = Average RF Power/ Duty Factor. CAUTION: A 1 KW pulsed amplifier must be designed as such. An amplifier rated at 100 watts CW and operated at a 0.1 duty factor will not deliver 1 KW peak. It will deliver 100 watts CW or pulse. Special pulse shapes (Gaussian, etc. ) require non-standard circuit designs. If you consider the whole system including the power supply, the power consumed is even more from the AC line as part of the station operation. A 25 amp power supply is usually considered just min. enough for a 100 watt rated transmitt. The power supply also has an efficiency that should be included for total understanding.

Problem I wanted to use an inexpensive (non-vacuum relay) to insert an attenuator in front of a high power HF amplifier for protection of the amplifier. The attenuator would be hot switched in during times of excessive drive or high reflected output power.
