When shopping for LMR-400, care should be taken to avoid purchasing inferior imitations of the genuine LMR-400 Times Microwave cable which can often lead to disappointment with final product performance. Cable length ranges from 50 to 1000 feet, spooled. What is the wattage rating on LMR 400 ??? cant a balun be made for 23cm ? I suppose the better commercial products will have datasheets with freq/loss graphs. This can power your Fridge, Sauna, Bathtub, dishwasher, and laundry machine. But Im no expert on fan dipoles, so read elsewhere to find people with more experience with them. A 400-watts inverter can handle 26.7 to 38.1 Amp power for input, and the output frequency is 60 Hz with a 3.2 to 3.6 Amp current rate. The jacket is bright red in colour which is made from Fluoropolymer. I was wondering if coax frequency plays a role in coax for 10 and 11 meter two way radio? LMR-400 v. Cable Experts CXP1318FX 6. For up to 20 ft of cable length a 10 gauge cable can handle 2000 watt and a 12 gauge speaker wire can handle 1960 watt. The same method of calculation can be used for any dedicated appliance circuit serving a single appliance. The higher quality coax cables do have a specification for their minimum bend radius during install. You need at least 3-4 times the line width of spacing, so for half-inch line youd need insulation 3-4 inches in diameter (0.5 x 4 x 2). less. 2. For example, if you're using 120 volts, multiply that by 200 amps to get 24,000 watts; 240 volts x 200 amps equals 48,000 watts. How flexible is LMR 400?

Hello Everyone, my name is Christian Nartatez, I am really grateful for this site, since I have a better understanding about FM Radio Transmission, thank you all for your comments, I am a pastor of a Baptist church in South America, I have been working with a 150W supposed transmitter, but the thing is that it never gets more than 60Watts of output when I measure with the Wattmeter, and SWR is below 1.5, also it is a strange thing that when setting up bellow 99Mhz dial the power drops to 30Watts, but when moving dial to 106Mhz or above the 105Mhz it goes up to 60Watts, I have tried: Dipole Standard antenna and also Dipole with Gamma Match and in both scenarios I am only registering that 60Watts and no more than that, and the cables I have tried are: RG8X and Times LMR400 and with both even 100Feet and 50Feet, measurements in watts are the same, it doesnt change, is this a problem of the transmitter? Most of the ceiling fan needs 50 to 120 watts of energy to run. Permanent heating appliances also have a fairly heavy electrical load, and most require their own dedicated circuits. To get this answer, pay your full attention to this section. 50 ohms is just a design point to match to 50-ohm coax. Secondarily on extension cord length.
