ATN Log periodic
 

Hi all

Was wondering if there is anyone out there who can help? I have just
purchased a 7 element ATN 18-30-7 log periodic that covers 18-30Mhz. I
believe there is another ATN aerial with the same boom length of 6 metres
that covers 14-30Mhz. I was hoping someone with one of these beasts could
advise the element lengths etc so i can convert mine to cover 20metres. I
assume i will need to rearrange the elements, drill alternate mounting holes
and change some element lengths and make some crossover straps for phasing
harnesses but thats just a formality. My aerial comes with a diagram of the
element lengths etc so was hoping someone could scan and send. I could start
from scratch and try and design a unit but this would save me a heap of
time. It appears that ATN is long gone. Any help would be greatly
appreciated. I have quite a collection of amateur radio related service
manuals in pdf and or jpg format so maybe i can return the favour.

email for reference is

Thanks in advance.
Cheers
