I just want to use the same antenna (like a 1/4wave as same as 1/2 wave, and maybe 1/8 ware) dipole for 80m and 40m and maybe 160m, and it will have different SWR at different bands.
I don't know how to interpret technically, but it seems to handle SWR to 20:1 with no problem. Am I right ? Is better to use the RD transistors than IRF510 in the aspect of handling SWR ?
I remember from BS170 and a "random wire" there were not much problem about SWR by it's low potency. But I do not know what happens at 5 watts or more.
Hello, I'm going to build my second 5W PA Kit, this time for low bands (80m, 40m and maybe 160m).I need to know how the IRF510 handles SWR ?
I tried to read the IRF510 datasheet and found no information about it. I read also the RH15HVF and the RD16HHF transistors, and found the following information :
Load VSWR tolerance VDD=15.2V,Po=16W(Pin Control), f=30MHz (or 175MHz),Idq=0.5A,Zg=50ohm, Load VSWR=20:1(All Phase) -> No destroy
