Subject: Re: Topband: Inverted J antennas?
Okay, over "medium" GND (0.005S/13) it has the same elevation
Hi Dave and thank you. That was quick.
I guess I should’ve been clearer with my question.
What does the elevation pattern look like please?

Hi Mike,
your inverted-J in EZNEC shows a radiation resistance at 1850kHz of 10
ohms. It is resonant at 1800kHz.
With the 50' vertical wire removed it is resonant at 2.7MHz and has a
radiation resistance at 1850kHz of 11 ohms.

Has anyone modeled an inverted J on 160m ? (almost an inverted U, really)
I currently have only one left (the other half of my 2-el array blew down
and I've been lazy to replace it) and it "works" but not as good as it could
I think if I had better supports (ie: taller trees, wider yard). I
