Hi Shockwave,

Thanks for the fast replay !

...But That is exactly what i am saying....how can you disagree with me ?

In my first answer:

1) I started off by saying it concernes quater wave verticals sitting on the ground.
2) In the attachement you can see the difference on 27mhz.
calculated by Eznec. With different heigths , so with the elevetad radials...
I also mention the difference is less when the antenna is higher in the air.

Now when a groundplane is placed at the ground the radials have the largest influence..
So that is why i would prefer to mention the differece when the antenna is placed at
0 feet. IF they are elevetad difference would be less significant..(as earlier mentioned)

I dont understand why you quote my entire reply and then just say...does not apply at all...
I disagree.... wouldnt the difference between 60 and 120 radials at 3,5 or 27mhz be nearly the same?

To my believe i have given the maximum difference. If you think otherwise please give me some facts.

About your remark about the 4 radials. I am not saying there will be a big improvement.
(not looking at t.o.a. because of differnet heigth)
we are talking about less the 3dB... (when the antenna is at the ground) at heigth as mentioned this is less... so again...why are you saying i am wrong?
Wasnt 6dB 1 s-unit and 2..3 dB of difference in gain is about the first the human ear could notice..

Kind regards,
Henry
