I think the base is magnetic for attaching to the hood of the car...!!!

BI CONE , central feed wide band (base is dielectric)

WAVY response Wide band..
-
I don't think so, anyway the base cone is electrically connected to the reflector.
-
THIS I SEE might be YOUR main problem...(Cut again to eliminate the bridging between CONES , it should be open and the disc is plastic)

,,,for those who want to optimize this antenna... Magnita.cst

RoundPatch.cst

An antenna with dual polarized, dual ports design, unexpected good results!!! RoundPatch.cst
-
,,,yes,it could be covered with a plastic... ,,,sorry for the mistake, D1=70 mm
-
Excellent ... now if I'm going to try JJJJ ... only the measures of the patches are missing on the edge of the reflector. Could it be covered with a specific plastic or can it be anyone? A question ... The square bester D1 would be 99 or 69?
-
D1=99 mm ,,,and because I saw that you like square patches...
-
Sorry, but the D1 measurements were missing.
-
Does it have two connectors...? Reactivity is high and Z should stay closer to 50 ohms... to be ideal...
-
It's pretty simple, you just post there what's here.
-
Hi, don't find a way to do this, please tell me and I'll move it
- Earlier
-
,,,,papagayor....I think your post should be here... Can you move it there...???
-
May the double port cause the lower dbi gain or the whole parts placement, also I did not add a component in this, it's a testing project and someone that knows more than me could modify it
-
You need something like this....
-
Here is the biquad, with what I'm connecting to you right now. The design is based of the model from martybugs.net website. The refletor dimension is about 154mm*143mm, I did it according to what I have. Everything is still experimental, luckily working but unfortunately with a fairly poor result.
-
Yes.. it looks good, I could try... give me more construction details
-
Trevor approach seems the Right on the money! BUT it's using an OFFSET DISH...No SHADOW from feed and different focus F/D ratio spillage etc,
