When modelling antennas and also building them it is obvious that
maximum gain comes about when resistance aproaches zero. Soooooooo
common sence says that the best antenna gain comes about when the anti
resonant point can be easily fed, welllll thats how my antennas work.
Unfortunatelly, the antenna was resonant on top band
but with a very low resistance so I have to start all over again. The
noise level did increase by 7 S units where modelling showed 9 dbi
gain ! Maybe I should use two radiators instead of the single one. O
well, I have to make changes so the anti resonance point is available
at top band. David, IT IS a topsy turvy world
so I am not available to listenning to the wobbly heads on the radio.
Oh shame for shame

Uh, resistance? Are you talking about DC resistance? What about impedence?

You also stated, "Unfortunatelly, the antenna was resonant on top band but

"maximum gain comes about when resistance aproaches zero." Which is it? Is
your low resistance good nor not?
