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? Tnx The electrical performance remains identical to LMR-400. LMR400 VS RG213: How Do They Compare? https://www.commscope.com/catalog/cables/product_details.aspx?id=1348.
