Dear Friends, A few months ago, I asked for advice getting a 40' high center support installed for my random length dipole fed with 450 ohm balanced line and tuned with a homebrew link-coupled tuner.
I would suggest that you think about shortening the length of your antenna (instead of lengthening it). I know that this sounds counter-intuitive, but take a look at L.B. Cebik's article on an 88 foo
ends I am a huge fan of 3-wire dipoles fed with 50 or 75 coax, where there is a center insulator (and balun) and 3-resonant dipoles attached to it. See the ARRL handbook for details. Cut each dipole
I strongly disagree. L.B. bases his recommendation for the 88' dipole on only one factor, the ability to maintain a broadside lobe between 3.5 and 14.5 MHz. That's not the only thing to consider. 1)

Since Derek feeds HIS dipole with 450 ohm line, feedline loss due to mismatch is not really much of an issue. de K1HI. . . Cebik ignored matching and feeline loss in that analysis and ONLY looked at
loss due to That's an incorrect assumption. If you look at the link I posed, it is for "ladder line" with large conductors. We also cannot dismiss or ignore tuner losses when matching short antennas

I would expect the shorter antenna to have a higher current maximum due to a lower radiation resistance. The longer antenna should have a lower current maximum, but the current will be distributed ov
gain and should power as It's possible to build all sorts of antennas in models that won't have the same benefits in real life if you leave feedlines and matching systems out of the model. 73 Tom __
