MMANA Antenna design data files

I designed some good performance ANTENNAs for 7/14/21MHz radio stations.
You can use them freely. I believe you will like their performance.

MMANA simulator designed by Mr.Mori / JE3HHT(C)


1. Inverted V dipole for 7MHz/40m band
Optimized for local communication. 
Communication distance between 0km-2,000km. 

Matching section is not necessary.





2. V dipole for 14MHz/20m band
Optimized for local and DX communication. 
Communication distance between 0km-40,000km.

Matching section is not necessary.






3. Optimized 2elements Yagi for 14MHz/20m band
Optimized for local and DX communication. 
Communication distance between 0km-40,000km.

Performance is almost same as 3 ele Yagi or HB9CV 2ele. 
and SWR is better than them.
Matching section is not necessary.
