Painted my antenna: reception much worse?


Hi All,

I have made this antenna. It works OK, i had no problems receiving digitenne signal with it.
Alan Yates' Laboratory - UHF Log-Periodic Array

Then I decided to paint this antenna white. Now the reception of 618MHz is very poor, while before painting i had no problems with it.
I do not know for sure if the paint is to blame.

I have measured the paint using a multimeter, and the DC resistance is >10MOhm

I have used this paint:
Brillux Halfgrund 850
"schnell trocknend rostpassivierent fur aussen und innen"

Is it possible paint affects the reception?
Best regards,

According to the website you used, that antenna is designed to receive 520-820 mHz, or channels 22-72. However, in the US there are very few remaining stations broadcasting above 698 mHz or channel 51. So, your antenna is not optimized for the current UHF television band.

I am not familiar with the type of paint you used and I don't read German so I can't comment about it. I can say if it was sprayed rather than brushed, its only a couple mils in thickness and it shouldn't affect the antenna significantly.



Hi Jim,

I have re-made the antenna (without paint), and the reception was just as bad. After some trial-and-error I realized my splitter was to blame.
I removed the splitter, and the reception was cristal-clear.

To answer your questions, I have brused the paint, at some places quite thick. :)
I live in the netherlands, to receive DVB-T (digitenne), one channel is transmitted on 818MHz

Thanks for your effort.
Best regards,

As long as the paint is non-conductive its effect on reception should be relatively minimal (I cant make this guarantee in every case)
