Hi, Thank you for your response. I do not have ladder line and only have the coax basically. Is it acceptable for good results to simply use the coax and then split it out to each direction of the copper wire? And not use the 1:1 balun? I was hoping to simply get the dipole in the air and leave it and simply tune it at the transmitter to acceptable SWR and go from there. Now I only get good SWR on the 80meters because of the length it is cut at. I was hoping also to use the dipole with the tuner on 10, 15, 20 and 40. Is this possible? The tuner is good and I know I will lose the power to the tuner but would still get to use the other bands when needed. Any more advice is greatly appreciated. thanks Bob The 1:1 balun isn't effecting the match on the other bands. If you remove it, there probably wouldn't be much difference at all. You could maybe put traps on the antenna so that it will be able to resonate on multiple bands. Another option would be to make multiple dipoles for the other bands. The impedance mismatch will make the signal tend to go down the dipole that corresponds to the desired band. Think of that sort of dipole as a fan so to speak. If you go this route, You'll want to trim the lowest band first, then work your way up in frequency for the other parts of the dipole. But all of these options are a good deal more work than the ladder line method. But if you won't or can't use ladder line due to your circumstances, I'd try the fan dipole. - Mike KB3EIA - |
