I used 450 ohm LL and trimmed the feed line length to 145ft to get an SWR on 40M of 2.2 without a tuner. There is only one LMR cable as LMR trademark is owned by Times Microwave. The 400 represents the cable diameter. The capacity of a power inverter could be measured by its watts, such as 400, 800, 1000 & more power watts inverter. But if you consider that a vent fan and bathroom light fixture might also be operating at the same time, you can see that a 15-amp bathroom circuit with a total capacity of 1,800 watts might be hard-pressed to handle such a load. required. Allowing these appliances to share a circuit with other devices can easily overload the circuit, since by nature they have a fairly heavy power draw, especially when they first startup. Hence, the amount of watts that a 12 volt 30 amp charge controller can handle is 360 watts, while a 24 volts 30 amps device can handle a maximum of 720 watts. Copyright 2000 -2004 Paul B.
