This is my new LPDA homemade antenna for UHF-AIR (225-400 MHz) The design was taken from an old magazine and recalculated for the frequencies of interest.
I'm posting more photos to give a better idea of the construction of this system LPDA. The elements are aluminum Ø8 mm and the two boom are 20 mm with a length of 1.50 m.
This is perhaps clearest example
I have done a mistake by 'stupid', has been the rush to mount the antenna or old age? Thanks for the advice, today I will to move items !!!!!
