According to EZNEC, a 1/2 wave dipole up 1/2 wavelength has a gain of 7.76 dbi at 27 degrees elevation. Most of this is due to ground reflection. My vertical has a gain of 0.72 dbi. So I can run 7db more power (500 watts)!!! 73 Roger On 11/12/2015 7:30 AM, Roy Koeppe wrote: “Kpa500 on 60 is il

“Kpa500 on 60 is illegal unless you have a *measured and documented* VERY lossy antenna that would reduce the effective radiated power to the same as 100 watts on a dipole. The simple 99 percent answer is that on 60m SHUT OFF the Kpa500 and run 100 watts barefoot.” Let’s see, “antenna tuner” loss
